1. Travel: The Distance from the initial offset to the second fitting
2. Advance: Distance parallel to the pipes between the offset fittings
3. Offset: Distance the pipe is offset from original position to new position
4. Rolling offsets formula: Travel = Rise x 2 = Spread x 2
5. What are the three ways water is present?: Solid - Ice
Liquid - Water
Gas - Steam
6. Pressure formula?: Pressure= Head x .434
7. Head Formula?: Head = Pressure x 2.3
8. Calculate the travel of 45 degree offset with a rise of 8" and a spread of
20": Travel = 21.54 x 1.414 = 30.45
Answer = 30 1/2"
9. Pressure is 60 psi, you must run a water service to a house built on a 30 foot
rise. What is going to be the pressure at the house?: Pressure = Head x .434
30 x .434 = 13.02 loss ( Uphill )
60 - 13 = 47
Answer = 47 psi
10. Volume of a pipe formula?: .0408 x D^2 x L
11. Calculate the volume of a tank ( pipe ) 20 feet in height, with a diameter of
48": Answer = 434,294,78 cu inches
* when we have cubic inches, must multiply volume by 231
(1880.06 gallons x 231)
12. Calculate 1 1/2" pipe with an advance of 48": Answer = 64 7/8 "
Travel = 1.414 x advance
1.414 x 48 = 67 7/8 "
Minus 3 ( 1 1/2 for both fittings )
= 64 7/8"
13. Payment formula?: Payment = Base x Rate
14. Rate formula?: Rate = Payment divided by Base
15. You estimated a job at $2195, you need $900 upfront, what is the percent
you collect upfront?: Answer = 41%
Rate = 900 divided by 2195 = 41%
16. When calculating offsets, what must be given?: Offset(Base) and Ad-
vance(altitude)
17. When can you use PVC schedule 40 water pipe?: Cold Water distribution
systems
18. When can you use CPVC water pipe and fittings?: Cold + Hot water distrib-
ution water systems

than 5 stories high tested?: You test each 5 story section with a 10 ft head of water
28. What prevents a chemical sink from being damaged?: Continually running
water and being manufactured out of chemical resistance materials
29. What is the purpose of a dip tube on a water heater?: Transfers water from
inlet to bottom of tank and helps prevent backsiphonage by having small hole at the
top of the dip tube
30. Air test on water supply lines?: 1 1/2 times the working pressure or 150 psi,
which ever is larger
31. What is the type of heating element used in electric water heaters?: Resis-
tance heating elements
32. Primary purpose of vent line in a water closet is?: Prevent loss from trap seal
33. What are the 2 primary water sources for public potable drinking water?: -
Surface and ground water
34. What is a cross connection?: When 2 separate piping systems one potable
and one undesirable flow into each other
Example: Garden hose attached to a silcock with the other end lying in a cesspool
35. What is the hydrologic cycle?: A continuous exchange of water among atmos-
phere, the earth, and water bodies
36. What device can be used to add a small amount of water to a floor drain
