FILTRATION SYSTEMS
Your filter system could be called the heart of your pool, as it is integral to maintaining water
quality. It is the filter, along with a good chemical routine, which enables you to experience clean,
clear, healthy pool water with minimal effort. The filter system consists of the filter tank, pump and
motor. More details on the pump and motor can be found in the
Pump & Motor
section.

Cartridge
Diatomaceous Earth
Sand
There are three types of filters: Cartridge, Diatomaceous Earth (D.E.) and Sand. Each system offers
specific advantages, and differ slightly in operation and the type of media that actually filters the
water (media refers to the sand, cartridge or D.E. inside the tank). Your

professional will
assist you in selecting the best filter type and model for your pool. The following pages provide
instructions for each type of filter.
Regardless of the type, your filter system should run 8 to 12 hours per day, or 24 hours a day on low
speed. When starting the filter for the first time make a note of the reading on the filter’s pressure
gauge once media has been added.
The initial reading is referred to as the normal starting
pressure, which can vary from system to system. As dirt and debris accumulate within the
filter the pressure gauge on the tank will rise, while simultaneously the return flow of water
going back to the pool diminishes. When the pressure gauge rises 7-10 psi above the
normal starting pressure it is time to backwash or clean the filter. Refer to instructions on
the following pages.
