SECTION 2 BEFORE YOU START TO INSTALL
HELPFUL INFORMATION
If you know little about plumbing skills, we suggest
you get a book on the subject. There are many good
books for do-it-yourselfers on the basics of plumbing.
You can get a low cost book from Sears Plumbing and
Heating departments that will help you. If you have
soldered before, some basic sweat soldering tips are
on page 20 of this manual.
WATER SYSTEM TESTS
HAS YOUR WATER SUPPLY HAD A CHEMICAL
ANALYSIS? Sears has many kinds of water treating
units {see page 6) to correct different water problems.
To know the kind and size of unit you need, you must
first know what elements are in your house water
supply. A chemical analysis shows the type and
amounts of elements in water. If your water needs
analysis, call or write your nearest Sears store for
help.
CHECK YOUR WATER PRESSURE - For your fitter
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 water inlet pipe
to the filter. NOTE; If water pressure during the day is 100
psi or more, pressure during the night may go over 125
psi.
If you have a well water system, look at the pressure
gauge to find the water pressure. Call your local water
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 5'/2 to 7 gallons per minute is needed. A lower flow
will keep your filter from working as well as it should.
To make an easy check of your flow rate, do the
following. You will need a 1 gallon container (can, jar,
pail, etc.).
1. Fully open 2 cold water faucets close to the point
water enters the house.
2. With both faucets open, fill the gallon container at
1 faucet while looking at a watch or dock to see
how many seconds it takes.
3. 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.
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.
