Water and Waste Holding Tanks & Fittings

Water / Waste Holding Tanks & Fittings - Defender offers parts galore and a selection of marine holding tanks for waste holding, black water tanks and marine water tanks that will fit just about any boat and application.

What size marine holding tank do you need?

Consider first the boat's needs. Defender offers a full line of marine holding tanks that will fit below any and all decks. The shape and size of your new marine holding tank, the location of the intake and the construction of the tank itself will more accurately determine how many gallons you need.

Boat holding tank construction ABC's.

Rigid tanks are built from polyethylene plastic that is super strong and holds odors inside. Sealed pipe fittings and plugs offer easy conversion from waste storage to water storage on most tanks at Defender. If flexible tanks are a necessity due to boat storage limitations look for 3-layer construction with welded seams.

How long do marine waste holding tanks last?

High quality marine holding tanks from Defender should last as long as your love affair with your boat! High strength plastic with pre drilled fittings and sealed plugs ensure that the chance for leaks are minimal and a holding tank placed under the deck will stay put for quite some time!
