Hayward Pump Housing With Strainer, 1-1/2" x 1-1/2" | SPX3100AAZ Afras the sandstone brick panels addWhat This Part Is Used For The Hayward SPX3100AAZ is a pump housing with integrated strainer listed as 1 1 2 inch x 1 1 2 inch connections. It forms the main wet end body and collects debris before water reaches the impeller. This assembly mounts directly to the motor and plumbing lines. Why This Part Matters Cracked housings can cause suction leaks and loss of prime. Damaged threads or union ports may lead to water loss at the equipment pad.
