Product details

The Pleatco PSR100-4 is a 100 square foot replacement cartridge for the Sta-Rite Posi-Flo cartridge filters. It is a single cartridge element, so one of these fills the housing.

Fitment

It covers the Posi-Flo 100GPM-TX, 100TX, 100TXR, II PTM100, T-100TX and T-100TXR. The body measures 8-11/16 inches across and 25-11/16 inches long, with both ends open and twelve concentric slots. Measuring the old cartridge is the fastest way to confirm you have the right one, since the Posi-Flo range shares a family look across several sizes.

Getting the life out of it

A cartridge holds its rated flow only while the pleats are open. Rinsing takes the surface dirt off, but oils and scale need a soak. When a soaked and rinsed cartridge still runs high pressure, or the fabric has gone thin and slack where it meets the end caps, it is done and a new element is the fix rather than another cleaning.

Questions and answers

What people ask about this product, answered by our pool techs.

Which filters does this cartridge fit?
Sta-Rite Posi-Flo models 100GPM-TX, 100TX, 100TXR, II PTM100, T-100TX and T-100TXR.
What are the dimensions?
8-11/16 inches outside diameter and 25-11/16 inches long, with open ends carrying twelve concentric slots.
How many cartridges does my filter take?
One. This is a single cartridge system, so the housing holds this one element rather than a set.
When should a cartridge be replaced rather than cleaned?
Once the pleats stay gray after a soak and rinse, or the fabric is thin, torn or flattened where it meets the end caps, cleaning stops recovering flow and it is time for a new one.
