Wholesale Marine carries Waste Holding Tanks, holding tanks can be used to store either freshwater supplies or marine toilet waste. Our Tanks are made from one piece molded durable polyethylene and meet Coast Guard standards. Our Tanks feature heavier walls and openings molded to eliminate stress cracking and leaking.
Appropriate for use as either water or waste holding, Fitting Relocation Kits are available to plug up existing threaded fitting openings and to custom position new fitting openings anywhere on the tank. Hose kits are also available separately.
