Before Starting Installation
Tools, Pipe, and Fittings, Other Materials

Pliers

Screwdriver

Teflon tape

Razor knife

Two adjustable wrenches

Additional tools may be required if modifi-
cation to home plumbing is required.

Plastic inlet and outlet fittings are included
with the filter. To maintain full valve flow,
3/4” or 1” pipes to and from the filter fittings
are recommended. It is important to main-
tain the same, or larger, pipe size as the
water supply pipe, up to the softener inlet
and outlet.

Use copper, brass, or PEX pipe and fit-
tings.

Some codes may also allow PVC plastic
pipe.

ALWAYS install the included bypass valve,
or 3 shut-off valves. Bypass valves let you
turn off water to the filter for repairs if
needed, but still have water in the house
pipes.

5/8” OD drain line is needed for the valve
drain.
Sizing Requirements
Water Pressure
The water system must have a pump large enough to deliver the recommended backwash
rate with a minimum pressure at the inlet of the filter of 30 psi. If the existing system cannot
do this, it must be upgraded to do so. Whenever possible, the water system should be ad-
justed to deliver at least 30 psi for even more satisfactory results
.
Backwash Flow Rates
The most important criteria in sizing a filter is the capacity of the pump. The water must pass
through the filter media at the proper service flow rate. The filter must also be backwashed
at a flow rate sufficient to dislodge and remove the captured particles. Failure to provide
sufficient water will cause a build-up of particles in the filter media, impairing its ability. In
order for your filter to backwash and rinse properly, your pump must be capable of providing
the backwash flow rates indicated on page 4 & 5.
