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.
