C. WATER SYSTEM TESTS
Has your water supply had a chemical analysis?
Please see page A on the inside of the front cover.
CHECK YOUR WATER PRESSURE -- For your
softener to work right, a water pressure of no lower
than 20 pounds per square inch (psi) is needed in the
house water pipes. The highest pressure allowed in
the water pipes is 125 psi. If pressure is over 125 psi,
buy and install a pressure reducing valve in the wa-
ter inlet pipe to the softener.
Note:
If water pressure during the day is 100 psi or more,
pressure during the night may go over 125 psi. Ad-
ding a pressure reducing valve may reduce the flow.
If you have a well water system, look at the pressure
gauge to find the water pressure. Call your local wa-
ter department if you have city water. They will tell
you what the water pressure is where you live.
CHECK YOUR WATER FLOW RATE -- A water
flow of at least 3 gallons per minute is needed. A
lower flow will keep your softener from working as
well as it should. To make an easy check of your flow
rate, do the following. You will need a one gallon
container (can, jar, pail, etc.).
_1_ Fully open two cold water faucets close to the
point water enters the house.
_J_ With both faucets open, fill the gallon container
at one faucet while looking at a watch or clock to
see how many seconds it takes.
_ Empty the container and go to the second faucet
(be sure BOTH faucets are still on). Fill the gallon
container at the second faucet and see how
many seconds it takes.
_Turn off both faucets. Now add the number of
seconds it took to fill the container at both fau-
cets.
_JA total of 90 seconds, or less, means the system
flow rate is good.
