TODD’s 9-gallon tank is designed for tight spaces where space is at a premium. It provides a compact solution that is easier to install on smaller boats. Best for: vessels with restricted deck or bilge space. Caution: capacity is limited, which may require more frequent pump-outs on actively used head systems.
Todd 851626WH Water/Holding Tank 13 Gallon
The Todd 13-gallon holding tank offers a middle-ground option for owners who need more capacity than 9 gallons without stepping up to 20 gallons. Best for: mid-sized boats with moderate wastewater flow. Limitation: select appropriate fittings and venting to prevent odors from escaping into living spaces.

Buying Guide
What tank size should I choose?
Choose capacity based on boat size, number of occupants, and typical voyage length. Small boats benefit from 9- to 13-gallon tanks, while larger boats or frequent pump-outs may require 20 gallons or more.
What material matters?
Most marine holding tanks use polyethylene for durability and odor resistance. Ensure the tank is compatible with your hull fittings and has secure mounting points to minimize movement and noise.
Why consider odor control and treatment?
Odor control is essential for comfort and sensor reliability. Consider integrated deodorizer options or enzymatic treatments to maintain tank cleanliness and easier pump-outs.
How important is pump-out compatibility?
Dockside pump-out compatibility simplifies maintenance. Check that the unit supports standard pump-out fittings and that the macerator or pump is appropriate for your discharge system.
Installation considerations
Assess bilge space, venting, and access for maintenance. Plan for secure mounting, hoses, and clamps to prevent leaks and reduce noise during operation.
Maintenance essentials
Regularly inspect seals, vents, and hoses. Use an appropriate deodorizer or enzymatic treatment as part of routine maintenance to keep tanks functioning well between pump-outs.
Safety and compliance
Follow local boating regulations for waste disposal and pump-out procedures. Ensure your system is integrated with your vessel’s safety and navigation equipment where applicable.
