BEFORE INSTALLING CHECKS AND TESTS
:
1C. WATER SYSTEM TESTS
HAS YOUR WATER SUPPLY HAD A CHEMICAL ANALY­
SIS? Please see page 2.
CHECK YOUR WATER PRESSURE - For your filter to
work correctly, a water pressure of no lower than
20
pounds per square inch (psi) is needed in the house wa­
ter 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 water inlet pipe and pipe
to the filter,
NOTE:
If water pressure during the day is 100 psi or more, pres­
sure during the night may go over 125 psi,,,Adding 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 you local water de­
partment 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
5-1 /2 to 7 gallons per minute is needed, A lower flow will
keep you filter 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,
2. 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,
3. Empty the container and go to the second faucet (be
sure BCTH faucets are still on). Fill the gallon container
at the second faucet and see how may seconds it takes,
4. Turn off both faucets. Now add the number of seconds
it took to fill the container at both faucets,
5. A total of 35 seconds, or less, means the system flow
rate is good.
