Hayward SPX3100D Threaded Strainer Cover

What This Part Is Used For
The Hayward SPX3100D is a threaded strainer cover used on compatible Hayward pump models. It seals the strainer housing and allows access to the pump basket for routine cleaning. This lid sits at the front of the pump where suction water first enters the system.

Why This Part Matters
A cracked or warped strainer cover can pull in air and cause the pump to lose prime. That leads to low flow, noisy operation, and potential seal damage. Replacing a worn lid restores proper suction and helps maintain steady circulation.
