Overview

The Attwood Marine 001001668 is a small replacement lid and gasket assembly for Attwood 4142-series gray water shower sump boxes. It uses a snap-in cover that can be removed for cleaning, and the gasket seats around the box opening to help keep gray water contained at the top of the sump.

This is the cover portion of the sump, not a complete box or pump. It is a practical replacement when the original lid is cracked, no longer sealing well, or has been removed often for filter access in a head, shower compartment, or other onboard drain area that feeds into a gray water sump.

Key features

• Small replacement cover assembly for Attwood 4142-series gray water shower sump applications
• Snap-in lid design for quick removal during cleaning and routine inspection
• Gasket included to help seal the sump box opening and reduce the chance of water escaping from the top
• Restores lid function without replacing the full sump box or pump

Compatibility and fit

This cover is the small version, so size matters before ordering. Match the part number on the existing lid or confirm the sump box is the Attwood 4142-series style, since Attwood shower sump systems have also been offered in larger box formats with different lid layouts.

For boats where the sump sits under a sole panel, behind a service hatch, or below a shower tray, the snap tabs make service work simpler because the lid can be lifted off without disturbing the rest of the drain plumbing.

Installation and service

When fitting a replacement lid, seat the gasket evenly on the box edge and press the cover down until the tabs snap fully into place. A properly seated cover helps the sump stay easier to service, especially on installations that collect hair, soap residue, and other shower debris over time.

Use on board

This part suits boats with a compact gray water sump that is opened regularly for filter checks or cleaning. It makes sense for owners who need the original cover function back without replacing the pump, wiring, or the sump box itself.
