Hayward SPX4000FG Drain Plug and Gasket
What This Part Is Used For
The Hayward SPX4000FG is a drain plug and gasket set used on compatible Hayward pumps. It seals the pump drain opening so the wet end holds water during operation, and it allows controlled draining for winterizing and service. This plug installs at the pump wet end drain port.
Why This Part Matters
A worn gasket or cracked plug can cause steady dripping under the pump and can also pull air if the drain port is not sealing correctly. During winterizing, a damaged plug makes it harder to drain the pump fully and increases freeze risk. Replacing the correct plug and gasket restores a reliable seal without overtightening. It is a common small part that prevents a lot of nuisance leak calls.

Installation and Fitment Guidance

About the Hayward Brand
Hayward builds an integrated lineup of pool equipment including pumps, filters, heaters, automation, cleaners, chlorination systems, and service parts. Their pumps are widely installed on residential pads, and small service parts like drain plugs keep winterizing and maintenance straightforward. Keeping seals intact helps the rest of the system run consistently without air issues. Hayward replacement parts are widely supported across the pool industry.
Common Service Context
Techs typically replace drain plugs when they see water under the pump or when the plug is stripped after repeated winterizing. It is often identified at spring startup when the pump drips from the drain port as soon as it fills.
