Basic
Principles
19
Basic Principles
The department is directed by KRS 318.130 through the State Plumbing Code Committee to adopt and put into
effect a State Plumbing Code. This code is founded upon certain basic principles or environmental sanitation and
safety through properly designed acceptably installed and adequately maintained plumbing systems. Some of the
details of plumbing construction may vary but the basic sanitary and safety principles desirable and necessary to
protect the health of the people are the same everywhere. The establishment of trade jurisdictional areas is not
within the scope of the code. The inclusion of a material even though indicated as approved for purposes of this
code, does not infer unqualified endorsement as to its selection of serviceability in any or every installation. As
interpretations may be required, and as unforeseen situations arise which are not specifically covered in this code,
the Department has traditionally used and will continue to use the following twenty-two principles to define the
intent
Principle No. 1. All occupied premises shall have potable water. All premises intended for human habitation,
occupancy, or use shall be provided with a supply of potable water. Such a water supply shall not be connected
with unsafe water sources, nor shall it be subject to the hazards of backflow or back-siphonage.
Principle No. 2. Adequate water required. Plumbing fixtures, devices, and appurtenances shall be supplied with
water in sufficient volume and at pressures adequate to enable them to function properly and without undue
noise under normal conditions of use.
Principle No. 3. Hot water required. Hot water shall be supplied to all plumbing fixtures which normally need or
require hot water for their proper use and function.
Principle No. 4. Water conservation. Plumbing shall be designed and adjusted to use the minimum quantity of
water consistent with proper performance and cleaning.
Principle No. 5. Safety devices. Devises for heating and storing water shall be so designed and installed as to
guard against dangers from explosion or overheating,
Principle No. 6. Use public sewer where available. Every building with installed plumbing fixtures and intended
for human habitation, occupancy, or use, and located on premises where public sere is on or passes said
premises within a reasonable distance shall be connected to the sewer.
Principle No. 7. Required plumbing fixtures. Each family dwelling unit shall have at least one water closet, one
lavatory, one kitchen-type sink, and one bathtub or shower to meet the basic requirements of sanitation and
personal hygiene. All other structures for human habitation shall be equipped with sufficient sanitary facilities.
Plumbing fixtures shall be made of durable, smooth, non-absorbent and corrosion resistant material and shall be
free from concealed fouling surfaces.
Principle No. 8. Drainage system shall be designed, constructed and maintained to guard against fouling,
deposit of solids and clogging, and with adequate cleanouts so arranged that the pipes may be readily cleaned.
Principle No. 9. Durable materials and good workmanship. The piping of the plumbing system shall be of
durable material, free from defective workmanship and so de3signed and constructed as to give satisfactory
service for its reasonable expected life.
Principle No. 10. Fixture traps. Each fixture directly connected to the drainage system shall be equipped with a
liquid seal trap.
20
Principle No. 11. Trap seal shall be protected. The drainage system shall be designed to provide an adequate
circulation of air in all pipes with no danger of siphonage, aspiration, or forcing of trap seals under conditions of
ordinary use.
Principle No. 12. Exhaust of foul air to outside. Each vent terminal shall extend to the outer air and be so
installed as to minimize the possibilities of clogging and the return of foul air to the building.
Principle No. 13. Test and plumbing system. The plumbing system shall be subjected to such tests as will
effectively disclose all leaks and defects in the work or the material.
Principle No. 14. Exclude certain substances from the plumbing system. No substance which will clog or
accentuate clogging of pipes, produce explosive mixtures, destroy the pipes or their joints, or interfere unduly
with the sewage-disposal process shall be allowed to enter the building drainage system.
Principle No. 15. Prevent contamination. Proper protection shall be provided to prevent contamination of food,
water, sterile goods, and similar materials by backflow of sewage. When necessary, the fixtures, device, or
appliance shall be connected indirectly with the building drainage system.
Principle No. 16. Light and ventilation. No water closet or similar fixture shall be located in a room or
compartment which is not properly lighted and ventilated.
Principle No. 17. Individual sewage disposal systems. If water closets or other plumbing fixtures are installed in
buildings where there is no sewer within a reasonable distance, suitable provision shall be made for disposing of
the sewage by some accepted method of sewage treatment and disposal.
Principle No. 18. Prevent sewer flooding. When a plumbing system is subject to backflow of sewage from the
public sewer, suitable provision shall be made to prevent its overflow in the building.
Principle No. 19. Proper maintenance. Plumbing systems shall be maintained in a safe and serviceable
condition from the stand point of both mechanics and health.
Principle No. 20. Fixtures shall be accessible. All plumbing fixtures shall be so installed with regard to spacing
as to be accessible for their intended use and for cleaning.
Principle No. 21. Structural Safety. Plumbing shall be installed with due regard to preservation of the strength
of structural members and prevention of damage to walls and other surfaces through fixture usage.
Principle No. 22. Protect ground and surface water. Sewage or other waste shall not be discharged into surface
or sub-surface water unless it has first been subjected to some acceptable form of treatment.

815 KAR 20:071. Storage and installation of Schedule 40, ABS and PVC plastic pipe and fittings.
RELATES TO: KRS Chapter 318
STATUTORY AUTHORITY: KRS 318.130
NECESSITY, FUNCTION, AND CONFORMITY: The office is directed by KRS 318.130 through the
Kentucky Housing, Buildings and Construction Advisory Committee, to adopt and put into effect a State Plumbing
Code. This administrative regulation relates to the method needed for storage, handling and installation of schedule
40, ABS and PVC plastic pipe and fittings. This administrative regulation is being amended because new fittings are
now available which allows for expansion when connecting plastic pipe to metal as well as a new means of
connecting different kinds of plastic pipe.
Section 1. Storage. (1) Pipe. Pipe shall remain in lifts until ready for use. Lifts shall not be stacked more than three
(3) high and shall always be stacked wood-on-wood. Loose pipe shall be stored in racks with a minimum support
space of three (3) feet. Pipe shall be shaded but not directly covered when stored outside in high ambient
temperatures to provide for free circulation of air and reduce the heat buildup due to direct sunlight exposure.
(2) Fittings. Fittings shall be stored in their original cartons to be kept free of dirt and to reduce the possibility of
damage. If possible, fittings shall be stored indoors.
(3) Solvent cement and primers. Solvent cement and primers shall not be exposed to ignition, sparks, open flames
or heat during storage and shall not be used beyond their marked shelf life.
Section 2. Handling. Care shall be exercised to avoid rough handling of pipe and fittings. They shall not be dragged
over sharp projections, dropped or have heavy objects dropped on them. Pipe ends shall be inspected for cracks in
the event of abuse prior to installation. (If transported by truck or trailer, piping shall be reasonably supported.)
Section 3. Installation. (1) Underneath concrete floors. Pipe and fittings shall be laid on stable earth conditions and
have four (4) inches of grillage on its bottom, top and sides. If ground is unstable, it shall be removed and the
excavation filled with grillage to the underneath side of the piping. Soil or waste pipe shall not be placed in a concrete
slab except those pipes that pass vertically through it.
(2) Above concrete floors. Horizontal piping shall be properly aligned and installed without strain. Piping shall not be
bent or pulled in position either before or after solvent welds have been made. It shall be supported at intervals not
to exceed four (4) feet and at the end of the branches and at the change of direction and shall be so installed as to
permit freedom of movement. Vertical piping shall be supported at their bases and all upward movement shall not
be restricted. Closet flanges shall be securely fastened to the floor through which it passes.
Section 4. Hangers. Hangers and straps shall be at least one (1) inch wide and shall not compress, distort, cut or
abrade the piping to allow free movement at all times.
Section 5. Making Solvent Cement Joints. (1)(a) Cement shall not be thinned. Cement that has thickened shall
be discarded. Cement shall not be used beyond its shelf life and shall not be subject to temperatures below thirty
(30) degrees Fahrenheit.
(b) Installers shall avoid prolonged breathing of vapors. Prolonged contact with skin is harmful. Install only with
adequate ventilation. Avoid contact with eyes and skin. Solvents are also flammable.
(2) Socket fit. ABS and PVC fittings are manufactured to a close tolerance. Joints shall be an interference fit between
pipe and fittings. Additional cement shall not be permitted for the correction of loosely fitted joints.
(3) Joining techniques. Piping shall be cut square with a saw or pipe cutter designed especially for plastic pipe. Pipe
and fittings shall be protected from serrated holding devices or abrasions.
(a) Burrs shall be removed from both inside and outside of the pipe. Dust, dirt and moisture shall be removed from
the surfaces that shall be cemented.
(b) Solvent chemical cleaner recommended by the company whose product is being installed shall be applied inside
the fitting and on the outside of the piping shall be joined.
(c) A paint brush shall be used to apply the solvent cement in a moderate, even coating in the fitting socket as well
as covering the pipe on the joining surfaces.
(d) Joints shall be assembled as quickly as possible before the cement dries. Insert the piping into the fitting socket
turning the pipe slightly to ensure even distribution to the cement. Hold the piping in a firm position so it does not
"back out" of the joint.
(e) Remove excess solvent cement from the exterior of the joint with a clean dry cloth. The joint shall not be handled
for a two (2) minute period. A fifteen (15) minute period shall be allowed for the joint to develop hanging strength.
(f) A Cemented pipe joint shall not be made in conditions of excessive moisture (ninety (90) percent humidity level)
or when the temperature is below forty (40) degrees or above ninety (90) degrees Fahrenheit.

815 KAR 20:072. Installation standards for cast iron soil pipe and fittings.
RELATES TO: KRS Chapter 318
STATUTORY AUTHORITY: KRS 318.130
NECESSITY, FUNCTION, AND CONFORMITY: The office is directed by KRS 318.130 through the
Kentucky Housing, Buildings and Construction Advisory Committee, to adopt and put into effect a State Plumbing
Code. This administrative regulation relates to the proper installation of cast iron soil pipe and fittings. This
amendment is necessary to bring the administrative regulation into technical compliance with KRS Chapter 13A. No
other substantive changes were made.
Section 1. The installation of cast iron soil pipe and fittings shall be made according to recommended
procedures, since care taken in installing will assure the satisfactory performance of the plumbing drainage system.
Section 2. Instructions for Cutting Cast Iron Soil Pipe. (1) During installation assembly, pipe and fittings shall be
inserted into the hub or into the gasket and firmly seated against the bottom of the hub or against the center rib or
shoulder of the gasket. To provide a sound joint with field cut lengths of pipe, it is necessary to have the ends cut
square and as smooth as possible with metal cutting saw or snap type cutters.
(2) Cast iron soil pipe, which may vary somewhat in toughness and resiliency, shall be cut with a twin-lever snap
cutter or a ratchet type cutter equipped with a chain which contains equally spaced beveled cutting wheels. The
following cutting procedure has been found to produce consistently good cuts:
(a) Position chain around pipe so that a maximum number of wheels are in contact with the pipe. Excessive space
between the first and last wheel in contact with the pipe is almost certain to produce a poor quality cut.
(b) Score the pipe before final pressure is applied to complete the cut. Apply only enough pressure to the lever or
ratchet handle to make the cutter wheels indent the pipe.
(c) Release the pressure and rotate tool a few degrees; then apply a quick final pressure to complete the cut. If a
piece of pipe is unusually tough, score the pipe several times and a good cut can be made. If the cutter wheels
become flattened or dull, it will be very difficult (if not impossible) to obtain a satisfactory cut. The life of the chain can
be extended by reversing the chain to obtain equal use of all the wheels. The mechanical features of a cutter shall
be kept in good working order.
Section 3. General Installation Instructions. (1) Vertical piping.
(a) Secure vertical piping at sufficiently close intervals to keep the pipe in alignment and to support the weight of the
pipe and its contents. Support stacks at their bases and at sufficient floor intervals to meet the requirements of local
codes. Approved metal clamps or hangers shall be used for this purpose.
(b) If vertical piping is to stand free of any support or if no structural element is available for support and stability
during construction, secure the piping in its proper position by means of adequate stakes or braces fastened to the
pipe.
(2) Horizontal piping, suspended.
(a) Support ordinary horizontal piping and fittings at sufficiently close intervals to maintain alignment and prevent
sagging or grade reversal. Support each length of pipe by an approved hanger located not more than eighteen (18)
inches from the joint.
(b) Support terminal ends of all horizontal runs or branches and each change of direction or alignment by an
approved hanger.
(c) Closet bends installed above ground shall be firmly secured.
(3) Horizontal piping, underground.
(a) When trenches are dug too deep, support the piping with approved grillage laid on firm ground as denoted in 815
KAR 20:130. To maintain proper alignment during backfilling, stabilize the pipe in proper position by partial backfilling
and cradling.
(b) Piping laid on grade shall be adequately secured to prevent misalignment when the slab is poured.
(c) Closet bends installed under slabs shall be adequately secured.
60
Section 4. Lead and Oakum Joint Installation. (1) Insert the spigot into the hub which has been properly cleaned.
(2) An oakum strand shall be inserted into the joint which is of a diameter that can be pressed into the joint by hand
and sufficiently long to make three (3) turns around the pipe. Drive the strand of oakum to the bottom of the joint
using a yarning iron. Pack the oakum solidly and evenly using a packing iron and hammer.
(3) Place additional strands of oakum into the joint until it fills the hub to within one-half (1/2) inch of the top, and
using a packing iron and hammer, pack this oakum until it forms a uniform surface one (1) inch from the top of the
hub.
(4) Pour molten lead into the joint at one (1) spot between the hub and spigot until it arches up slightly above the top
of the hub.
(5) When the lead has cooled, drive it down at four (4) points around the hub using a caulking iron to insure uniform
caulking.
(6) Caulk the joint on the inside and outside edges using a sixteen (16) ounce ball peen hammer and appropriate
caulking irons.
Section 5. Compression Joint Installation. (1) Fold and insert the one (1) piece rubber gasket into the hub which
has been properly cleaned.
(2) Apply special gasket lubricant to the spigot and inside of the neoprene gasket.
(3) Push, draw or drive the spigot into the gasketed hub with a pulling tool or suitable device.
Section 6. No-hub Joint Installation. (1) Clamp and gasket installation. The following procedures shall be taken to
insure a proper joint:
(a) Place the gasket on the end of one (1) pipe and the stainless steel or cast iron clamp assembly on the end of the
other pipe.
(b) Firmly seat the pipe ends against the integrally molded shoulder inside the neoprene gasket.
(c) Slide the clamp assembly into position over the gasket and tighten the bands or clamps as described below.
(2) Torqueing bands. A properly calibrated torque wrench, set at sixty (60) inch pounds shall be used. The following
procedure for applying torque to the band assembly shall be used: The stainless steel bands shall be tightened
alternately and firmly to sixty (60) inch pounds of torque.
(a) Step 1. The inner bands shall be tightened alternately and firmly to sixty (60) inch pounds of torque.
(b) Step 2. The outer bands shall be tightened alternately and firmly to sixty (60) inch pounds of torque.
(3) Torqueing clamps. A properly calibrated torque wrench, set at 175 inch pounds shall be used. The following
procedure for applying torque to the clamp assembly shall be used: The stainless steel bolts shall be tightened
alternately, gradually and firmly to 175 inch pounds torque. (9 Ky.R. 657; eff. 12-1-82; Am. 10 Ky.R. 1010; eff. 3-31-

Section 1. Storage and Handling. (1) Chlorinated polyvinyl chloride (CPVC) pipe, tubing, and fittings shall be
stored under cover to avoid unnecessary dirt accumulation and long-term exposure to sunlight. Pipe and tubing
shall be stored with continuous support in straight, uncrossed bundles. Care shall be used in handling to avoid
unnecessary abuse such as abrasion on concrete or crushing.
(2) Solvent cement and primers, because of flammability, shall be stored in an area where there shall be no
exposure to ignition, sparks, open flames, or heat. Solvent cement and primers shall not be used beyond their
marked shelf life.
Section 2. Installation. Correct assembly shall consist of the following steps:
(1) Cutting the pipe square;
(2) Removing burrs;
(3) Cleaning both pipe end and fitting socket with a recommended CPVC cleaner, unless using an approved one
(1) step cement;
(4) Applying a liberal coat of CPVC solvent cement to the pipe and apply a light coat of cement to the fitting socket;
removing all excess cement from the interior which may clog the waterway;
(5) Assembling immediately by bottoming the pipe in the socket and rotating one-quarter (1/4) turn as the joint is
assembled;
(6) Removing excess cement from the joint; and
(7) Determining if the joint has been properly assembled by looking for a small bead of cement to appear at the
junction between the pipe or tubing and the fitting.
Section 3. Installation Temperature. Extra care shall be taken if installing in temperatures below forty (40)
degrees Fahrenheit or above 110 degrees Fahrenheit. The manufacturer's installation instructions shall be
followed carefully.
Section 4. Hangers and Supports. Support shall be provided at each floor level for piping installed in vertical
runs. For horizontal runs, support shall be provided at three (3) foot intervals for pipe one (1) inch or less in
diameter and at four (4) foot intervals for larger pipe sizes. Piping shall not be anchored tightly to a support but
secured with smooth straps or hangers allowing for movement caused by expansion and contraction. Hangers
shall not have rough or sharp edges that come in contact with the piping.
Section 5. CPVC-to-metal Transitions. CPVC threaded adapters shall not be used to transition from CPVC to
metal. Union type fittings that use gaskets or O-rings to seal dissimilar connections shall not be used. Compression
type transition fittings, over-molded transition fittings and push-type fittings that meet the ASSE 1061 standard

To find the length of a forty-five degree offset: Multiply the distance between the two parallel lines by the
constant 1.414.
For offsets that are not greater than 3 feet: The following is a good rule for 45-degree offsets, but not close
enough for long offsets. Add to the distance between the two parallel lines pipe, 5 inches for each foot of such
distance, and at the same rate for fractional parts of a foot. This would mean the addition of 5/12

The weight of one US gallon of water is 8 1/3 lbs.
One cubic foot contains 7.48 US gallons.
Pressure per square inch of a column of water is 0.434 X height in feet.
To find the pressure in pounds per square inches at the base of a column of water: Multiply the head or
height in feet by .434.
To find the head, when pressure per square inch is known: Divide the pressure by .434.
To find the volume of any rectangular or a cylindrical tank: Multiply the area of the base X height.
To find the volume of a rectangular tank: Multiply length X width X height.
To find the volume of a cylindrical tank: Multiply R² X 3.1416 X Height or D² X .7854 X height.
To find the volume of a rectangular or cylindrical tank in US gallons: When dimensions are given in inches,
divide the number of cubic inches by 231.
To find the volume of a cylindrical or rectangular tank in US gallons: When dimensions are given in feet,
multiply the number of cubic feet X 7.48.
To find the cubic contents of any length of pipe of any size: First find the cubic contents of one foot of pipe,
and then multiply that amount by the number of feet of pipe. If these dimensions are in inches, the result will be
in cubic inches. If the result desired is gallons, as it generally will be divide the result in cubic inches by 231,
there being 231 cubic inches in one gallon.
A short method of finding the number of gallons in a foot of pipe of a diameter: Multiply the square of the
inside diameter of the pipe by .0408.
Rule for Estimating the Pitch of a Pipe: Divide the total drop or fall of the pipe, measured in inches, by the
horizontal distance between the two ends of the pipe, measured in feet. The result will give the pitch per feet in
fractions of an inch.
To find the circumference of a circle: Its diameter being given, multiply the diameter by 3.1416. The product
will be the circumference.
To find the diameter of a circle the circumference being known: Divide the circumference by 3.1416. The
result will be the diameter.
To find the area of a circle when the diameter is known: Square the diameter and then multiply by .7854.
Circumference of Circle = 3.1416 X Diameter
Area of Circle = 3.1416 X Square of Radius
To find the cylindrical area of a cylinder: Multiply the circumference of a circle by the length of the cylinder.
To find the cubic content of a cylinder: Multiply the area of its circle by the length of the cylinder.
To change a common fraction to a decimal: Divide the numerator by the denominator, and point off the right
number of decimal places.
To add decimals: Arrange the numbers so that the decimal points are in line, and then carry out the addition as
for whole numbers.
To multiply two decimals: Arrange the two numbers regardless of the location of their decimal points. The
multiplication of the numbers proceeds exactly as in the case of multiplying two whole numbers together. The
proper location of the decimal point in the answer is determined by the following: In the product of the two
numbers the decimal point should have as many numbers to the right of it as the sum of the numbers to the right
of the decimal points of the two numbers that are multiplied together.
119
To divide two decimal numbers: Divide the two numbers without regard to the two decimal points. Just as in
the division of two whole numbers, subtract from the number of decimal places in the dividend the number of the
decimal places in the divisor and the remainder will be the correct number of figures to the right of the decimal
point in the quotient, which will be the answer required.
To change per cent into a common fraction: Write the number expressing the per cent as the numerator with
100 as the denominator. Often such a fraction may be simplified by reducing it to its lowest terms.
To change a number written with a per center sign into a decimal: Omit the per cent sign and move the
decimal point two places to the left.
To change a decimal to per cent: Shift the decimal point two places to the right.
To change a common fraction into per cent: Reduce the fraction to hundredths, omit the denominator and
place the per center sign after the numerator.
To find a required per cent of a number: Multiply the number by the given per cent.
In this method, the number below the line shows the number of equal parts into which the whole is
divided and is call the denominator. The number of equal parts taken is shown above the line and is
called the numerator. According in speaking of ¾ of a pound, the denominator, 4 shows the pounds
divided into four equal parts and the numerator, 3 shows that three of these four parts are taken or set
aside for some special purpose.
A fraction can be changed to higher terms (without changing its value) by multiplying both numerator
and denominator by the same number and to lower terms, (without changing its value) by dividing both
numerator and denominator by the same number.
To reduce a mixed number to an improper fraction: Multiply the whole number by the denominator of the
fraction, then add the numerator to the result and place the result over the denominator.
To reduce two or more fractions to fractions having a common denominator: After deciding what the
common denominator is to be , multiply each of the several numerators by the number of times its denominator
is contained in the common denominator.
To add two or more fractions: Reduce the fraction to fractions having a least common denominator. Then add
the numerators of the fractions and place the sum over the common denominator, this fraction will be the
answer required.
To subtract fractions: Reduce them to fractions having a common denominator. Then, if necessary reduce the
result to its lowest terms and in the case of an improper fraction reduce it to a mixed number.
When mixed numbers are to be subtracted: Subtract the fractions and the whole numbers separately.
When the smaller mixed number is a larger fraction than the larger mixed number: Borrow 1 from the
whole number of the larger mixed number and add it to its fraction and then proceed to subtract.
When the larger number is a whole number and smaller is a mixed number: Borrow 1 from the whole
number.
In cancellation, any factor above the line may be divided (if without remainder) into any factor below the
line and any factor below the line may be divided into any factor above the line Multiply together the
numbers remaining above the line for the numerator and the number remaining below the line for the
denominator. If no number remains above the line, use 1.
To multiply a fraction by a fraction: Multiply the numerator together for the numerator of the answer and the
denominators together for the denominator of the answer. Cancel whenever possible.

Method of Making a Square
Nail together two straight pieces of 1 x 2 board to form an L as shown in
Figure 25.
Mark off a point 3 feet from the corner on one of the boards.
Mark off a point 4 feet from the corner of the other board.
Cut another board exactly 5 feet long. Line up this board with the points marked
on the other two boards.
NOTE: These measurements can have doubled to make a larger square or they may be cut in half to make a
smaller square.
Capacities of Tanks
Cylindrical Tanks
Formulas:
C = capacity in gallons
D = diameter
L = length
When measurements are in inches:
C = D x D x 0.7854 x L
231
When measurements are in feet:
C = D x D 0.7854 x L x 7.48
Example:
How many gallons of water will a tank hold which is 3 feet in diameter and 12 feet long?
C = D x D 0.7854 x L x 7.48
C = 3 x 3 0.7854 x 12 7.48 = 634.477 or 634 ½ gallons
121
To find the volume of a rectangle tank: Multiply length x width x height.
Formulas:
C = Capacity
L = Length
W = Width
H = Height
Example
10’ x 3’ x 5’ = 150 cu. ft.
150 x 7.48 = 1122.00 gallons
To find the volume in US gallons: Multiply the number of cubic inches by 231
7.48 gallons = 1 cubic foot 231 cubic inches = 1 gallon
Mechanical Engineers and Architectural blueprints usually give the city sewer main and the building
drain invert elevation (inside bottom of the barrel) in feet and decimals of a foot.
Plumbers work with feet and inches of a foot; therefore, plumbers must change feet and decimals of a foot to
feet and inches.
Rules for estimating the pitch of a pipe:
Divide the total drop or fall of the pipe, measured in inches by the horizontal distance between the two ends of
the pipe measured in feet. The result will give the pitch per feet in fractions of an inch.
Pitch to Grade
Pitch Grade
1/16” 1/2 %
1/8” 1%
1/4" 2%
1/2" 4%
Total Drop 3 ¾” or 3.75
3.75 divided by 30 = .125 or 1/8” per foot
122
To find the pressure in pounds per square inch at the base of a column of water:
Multiply the head or the height in feet by .434
Example
15’ x .434 = 6.51 lbs. or 6 1/2 lbs.
