Todd Water & Waste Tanks

Todd Water & Waste Tanks: Versatile Marine Storage Solutions

Todd has earned a reputation in the marine industry for producing robust, dual-purpose tank systems that simplify boat plumbing installations. Their water and waste tanks stand out for their innovative design approach: each Todd Tank comes with the necessary pre-drilled and threaded openings so that it can be configured as either a Water Tank or as a Holding tank. This versatility makes Todd tanks particularly valuable for boat builders, retrofitters, and DIY enthusiasts who need flexible storage solutions without maintaining separate inventory for fresh water and sanitation applications.

Construction and Compliance Standards

Constructed of one piece molded durable polyethylene, these tanks comply with FDA regulation CFR 177.1520 and meet Coast Guard standards. The manufacturing process involves rotational molding, which creates seamless tanks without weak points or seams that could fail over time. Manufactured from SURPASS® polyethylene, these tanks meet or exceed US Coast Guard (Type III CFR 177.1520) requirements, ensuring they're suitable for both potable water storage and waste containment aboard recreational and commercial vessels.

One of Todd's key design advantages is odor and taste neutrality. Todd waste/water holding tanks are tough and durable and will not emit waste odors or change the taste of fresh potable water. This characteristic is critical for marine applications where the same tank model might be used for drinking water on one vessel and sanitation on another, depending on configuration needs.

Standard Features and Configuration Options

Standard tanks include two 1 1/2"fill/drain ports and two 1/2" vent/supply ports-which enables use as a sanitation holding tank or for potable water storage. All openings are female NPT (National Pipe Threads) and are located in the same relative position one end of the tank, which simplifies installation planning and ensures consistent mounting across Todd's product line. The tanks ship with plugs installed, allowing installers to open only the ports needed for their specific application.

For custom installations, Todd offers fitting relocation kits that provide additional flexibility in plumbing layout. Holding tanks have a heavier wall thickness than water tanks and feature (2) 1.5" and (2) .5" openings, with the enhanced wall construction providing extra durability for waste containment applications. Todd specifies that flexible hose connections must be used rather than rigid piping to maintain warranty coverage and allow for the slight expansion and contraction that occurs in marine environments.

Why Marine Professionals Choose Todd Tanks

The dual-configuration capability eliminates the guesswork when ordering replacement tanks or planning new installations. Boatyards can stock fewer SKUs while still meeting diverse customer needs, and boat owners appreciate the straightforward installation process with clearly marked, pre-threaded ports. Whether you're replacing a failed fresh water tank or upgrading your vessel's sanitation system, Todd's water and waste tank lineup provides Coast Guard-compliant solutions built specifically for the demanding marine environment.
