10" Filter Kit - Clear Canister Housing with 10" Filter

Your pump is a PRECISION MACHINE. Traces of sand, clay, rust or other solids will cause rapid wear or immediate damage, just as they would in your automobile engine. If your water is CRYSTAL-CLEAR ALL THE TIME, our Fine Intake Strainer will provide sufficient protection. If you have an intake strainer already, it is probably not fine enough -- openings must be no more than several hairs wide, or additional filtration is required. Since water conditions are subject to change, it is good insurance to use a filter regardless. Many dealers refuse to sell our pumps without a filter since it minimizes call-backs.

A filter cartridge may look clean and still be clogged, due to fine silt embedded in the fibers. If the pump becomes increasingly noisey over time, it is usually due to a clogging filter cartridge. On the other hand, a cartridge that looks discolored may not be clogged. As long as your pump runs quietly, the filter is OK. Use pump noise to indicate the need to change cartridges.
