Product details

The Pleatco PSR137 is a replacement filter cartridge for the Sta-Rite Posi-Flo II family, listed for the PTM 135 and for the 35 TX and 35 TXR.

Checking the fit

The element measures 8-11/16 inches across the outside diameter and 31-1/4 inches long, and the open end carries 12 concentric slots. Pulling the old cartridge and measuring it is the surest way to confirm the match, because Sta-Rite housings of similar size take different elements.

When to replace

Cartridges do not last forever. Once the pleats stay grey after a proper soak and rinse, or the pressure climbs back to where it was within days of a clean, the media has loaded past recovery. A tired element drives filter pressure up, cuts flow through the pump and lets fine dirt back into the pool.
