Pentair R38004 Pump Strainer Basket (5" Style) for AquaFlo / Premier / Sta-Rite Applications
The Pentair R38004 is an OEM replacement pump strainer (trap) basket designed for select Pentair AquaFlo-style pump strainer pots. It sits inside the pump basket chamber to collect leaves and debris before they reach the impeller, helping maintain strong flow, protect the wet end, and reduce clog-related strain on the pump.

What This Basket Does
- Captures larger debris before it reaches the impeller to help prevent clogs and loss of prime.
- Helps maintain steady suction and flow for better filtration performance.
- Reduces wear caused by debris restriction and cavitation inside the wet end.
When to Replace
- Cracks, splits, or broken ribs that allow debris to bypass the basket
- Warping or deformation that prevents the basket from seating flat
- Basket collapses under suction or repeatedly pops out of position
- Debris consistently reaches the impeller area
Installation and Maintenance Tips
- Turn off power at the breaker before opening the pump lid.
- Remove the old basket, clean the strainer pot, and ensure the new basket seats flat and stable.
- Clean and inspect the pump lid O-ring; lightly lubricate with pool-safe silicone lubricant if needed.
- Empty the basket frequently during heavy debris seasons to keep suction strong and reduce motor load.
