Hayward SPX5500C Strainer Housing

What This Part Is Used For
The Hayward SPX5500C is a strainer housing used on compatible Hayward pumps. It is the pump basket housing where water enters before the impeller, catching debris to protect the pump. This part is located on the front wet end of the pump at the equipment pad.

Why This Part Matters
Cracks in the strainer housing can cause persistent leaks, air intrusion, and prime problems that get worse over time. A compromised housing can also prevent the lid and O-ring from sealing correctly, even with new seals. Replacing the correct housing restores structural integrity and consistent suction sealing. It is commonly replaced after freeze damage, overtightening, or impact during service.
