The short answer: A pool pump basket is a part-number purchase. Do not order by appearance alone, because a basket that is slightly too tall or narrow can damage the housing or leave debris around the impeller.
Our picks
The pump basket sits under the clear lid and catches debris that made it past the skimmer. It is simple, but it protects a more expensive pump part. Most replacement mistakes come from assuming baskets are interchangeable. They are not.
The Pentair 070387 Strainer Basket was checked on a live US Amazon listing. It has a rating above 4.0 stars, thousands of substantive reviews, and repeated owner notes about matching compatible WhisperFlo and IntelliFlo pumps. This recommendation is based on listing and review research, not a hands-on fit test.
Read the pump label first
Turn off power at the breaker before opening the pump. The label on the motor or housing gives you the pump family and model. Write it down, then use the manufacturer part number where possible. A photo of the old basket helps, but it is not enough on its own.
For compatible Pentair pumps, the 070387 basket is a common genuine replacement. It is not a universal basket. If the label says Hayward, Jandy, or another Pentair family, stop and check that model's parts diagram.
Look for damage that actually matters
A small stain is not a reason to replace a basket. Cracks, broken ribs, a missing handle, or a warped rim are. Those faults let debris slip around the basket or prevent the lid from sealing correctly.
Empty the basket before it is packed. Pulling a jammed mass of wet leaves out by the handle is a good way to break an otherwise usable basket. Rinse it with a hose and inspect the bottom where cracks can hide.
Open the lid safely
Switch off the pump, release pressure according to the equipment manual, and wait for the system to stop. Open the lid, lift out the basket, and remove debris. Inspect the lid O-ring for grit or flattening before putting everything back.
Never force a replacement basket into the housing. If it does not drop in naturally, you likely have the wrong part or debris caught in the seat. For a related pressure check, see our pool filter pressure gauge guide.
Do not confuse it with the skimmer basket
The skimmer basket catches debris at the pool wall. The pump basket catches what gets past it. They have different shapes, locations, and part numbers. If you need the wall-side replacement, see pool skimmer baskets.
Bottom line
Replace a pool pump basket when it is cracked, warped, or no longer fits the housing correctly. The Pentair 070387 is a dependable OEM option for its listed Pentair pump models. Check your equipment label before ordering, clean the lid seal, and never run the pump without a basket.
