Todd SURPASS™ 55-Gallon Water / Holding Tank
A heavy-duty, one-piece molded tank built for permanent marine installation. The Todd SURPASS™ 55-gallon tank is engineered for use as either a freshwater potable water tank or a waste holding tank, and it’s built to the standards that matter: FDA-compliant materials that won’t leach odors or affect water taste, and full U.S. Coast Guard compliance for holding tank applications. All openings are female NPT (National Pipe Thread) and are grouped at one end of the tank for straightforward plumbing runs. Plugs are included so the tank is ready to install right out of the box.

Parts Desk Insights
The 55-gallon capacity makes this tank a strong fit for cruisers, liveaboards, and larger offshore boats where extended range between fill-ups or pump-outs matters. The SURPASS™ material is the key differentiator — it’s genuinely odor-neutral and potable-water safe, so the same tank can serve either application depending on how you plumb it. If you’re installing or replacing fittings, the Todd Marine Water Tank Straight Adapter Kit is designed to work with these tanks and simplifies the connection to standard hose.
