1. How do you calculate GPM for a pool pump? - Correct Answer: Most
pool pump specifications are expressed in gallons per minute (GPM). So, to
convert from GPH (gallons per hour) to GPM, divide your GPH by 60
minutes - 2531 GPH / 60 = 42.2 GPM
ex: 14400 gallon pool turn over in 6 hours is: = 40 gpm
2. When establishing the elevation of a swimming pool bond beam on a
residential pool, which of the following must be considered? - Correct
Answer: Deck drainage and coping thickness
3. Which of the following pipes is approved for underground gas lines? -
Correct Answer: Polyethylene pipe (thick yellow plastic piping weve used for
BBQ's)
4. why? Poly pipe has all of the advantages of Flex PVC, with greater chemical
and bacteria resistance, it doesn't attract hungry insects, and can withstand
some freezing or ground movement without breaking
,5. what is bond beam in a pool ? - Correct Answer: A bond beam is a thick
course of concrete that fills in the space along the top of the pool, all the
way around the perimeter. It creates a barrier between the pool and the
surrounding dirt
6. Joints for copper tubing may be - Correct Answer: brazed, soldered, and
made with compression fittings.
7. If you overdig while excavating for a Fiberglas pool, what would be the best
backfill to use? - Correct Answer: Concrete
8. how do you measure concrete? How many cubic yards of concrete will be
required for the 4" thick slab deck surrounding the spa shown below? -
Correct Answer: 11.7 what is the formula
9. What is the minimum height of a fence around a commercial swimming
pool - Correct Answer: 4 FT
10.Capacity formula - Correct Answer: Pool volume(Cubic feet) x 7.48 =
pool capacity in gallons
11.First you'd need to figure out the pool volume, so simply plug these
numbers into the volume equation and multiply: 40 x 20 x 5 = 4,000 cubic
feet (pool volume).
,12.What size high-rate sand filter is needed for a 30,000 gal swimming pool?
- Correct Answer: 3.1 sqft at least 1 square foot per 10,000 gallons pool
capacity.
13.Which type of copper water pipe is best to use underground? - Correct
Answer: k
14.what is type k copper ? - Correct Answer: Type K, soft copper tubing,
remains free from rusting and is highly resistant to corrosion and scale
formation. Type K has a heavy wall thickness for underground ser- vices
from the water main to the house connection. It is conductive to enable
thawing and its flexibility allows it to conform to underground trenching.
15.If pool water has a low pH, what is a concern? - Correct Answer: eye
iritation
Aim for a pH level of between 7 and 7.6. If the water pH is higher than 8,
anyone who swims in the pool is at risk of skin rashes, while a pH of lower
than 7 can sting swimmers' eyes.
16.In fountains, all lighting fixtures must be installed for operation at _____ or
less between conductors. - Correct Answer: 150 volts
17.Chlorine should be added to a pool: - Correct Answer: in the evening.
since liquid chlorine will burn off quickly in direct sunlight, it's best to add it
to your pool in the evening.
, 18.What maximum slope is specified by the Building Code for a required
handicap ramp? - Correct Answer: 1:12 (8.3%)
19.Doubling the diameter of a pipe will produce: - Correct Answer: 4 times
the water flow capacity of the pipe.
although, it will flow more water the result will decrease ion velocity
20.How do you remove scale from gunite? - Correct Answer: drain, power-
sand, and acid-wash
21.Add _____ to the pool water if the phenol-red indicator turns the water
sample red. - Correct Answer: acid
22.There is loose fill on a hillside. What should the pool contractor tell the
owner? - Correct Answer: a subgrade foundation to support the pool is
needed
23.Ground pressure can cause pool walls to crack or split. What can be done to
prevent these problems? - Correct Answer: Keep the pool filled all year
round.
A drained pool can crack or be pushed upward because of it offers little
resistance to underground water pressure.
24.Elemental Chlorine aka Gas Chlorine - Correct Answer: It is stored in a
pressure tank and fed into the recirculation system via an automatic feeder.
