The Johnson Pump Black Basket is a direct replacement strainer basket for Johnson Pump’s 4000 GPH bilge pumps, restoring debris protection once the original basket has cracked or gone missing.
A worn or missing basket leaves the pump’s high-flow inlet exposed to debris that would otherwise get filtered out, one of the more common causes of a bilge pump jamming under heavy load.
It’s a straightforward, inexpensive fix that keeps a high-output 4000 GPH pump protected without needing to replace the whole unit. Shop more bilge pump switches and accessories.
