Hayward SPX1705AA Pump Housing With Cover

What This Part Is Used For
The Hayward SPX1705AA is a pump housing with cover for compatible Hayward pump models. It forms the main wet end body where the strainer basket and water chamber live. This housing connects to the suction and return plumbing and mounts to the motor assembly.

Why This Part Matters
A cracked housing can leak under pressure or allow air to enter, causing priming problems and unstable circulation. Housing damage is common after freeze events, overtightened fittings, or prolonged UV exposure. Replacing the housing restores a solid foundation for the pump’s internal components.

About the Hayward Brand
Hayward builds complete residential pool systems including pumps, filters, heaters, automation, cleaners, chlorination, and service parts. Their pump wet ends are designed to be repairable so housings and internals can be replaced without reworking the whole pad. Keeping the pump body sealed and structurally sound protects circulation performance. Genuine Hayward housings help maintain proper fit with internal components.

Common Service Context
Techs usually replace housings when they see visible cracks, persistent leaks at fittings, or freeze damage around the strainer body. It is also a common repair when a pump is being rebuilt and the existing housing is worn or warped.
