Overview
The Attwood Marine 99202WS1 is a waste deck fill with a plastic neck and a stainless steel cap for boats that use a 38 mm sanitation hose. It is a non-vented fitting, uses a 54 mm deck cutout, and has an 85 mm cap diameter, so the key fit checks are hose size, deck opening, and the flange footprint on the surface of the deck.
This fitting is for waste service, not fuel or freshwater, and the cap is marked accordingly to help keep deck fills clearly identified. That matters on boats with more than one fill point, especially when fuel, water, and sanitation access points are grouped in the same area.
Key features
- Waste deck fill for sanitation pump-out systems.
- 38 mm hose connection size for matching existing waste hose runs.
- 54 mm deck cutout requirement for replacement planning or new installation.
- 85 mm cap diameter for checking flange coverage at the deck surface.
- Plastic neck with a stainless steel cap.
- Non-vented body for systems where tank venting is handled through a separate vent line.
- Waste marking on the cap helps avoid confusion with fuel or water fills.
Installation and fit
On a replacement job, the practical checks are straightforward: confirm the hose is 38 mm, measure the existing deck opening, and make sure the 85 mm cap will sit cleanly over the area on deck. It also helps to check clearance below the mounting point so the hose can run without a sharp bend right under the fitting.
This is a good match for cruisers, fishing boats, and sailboats with an onboard head and holding tank where you need a clearly marked waste pump-out point on deck. If your boat already has a separate tank vent and you are matching a non-vented waste fill in this size, this fitting lines up with that type of setup.
