Product Details

Moeller holding tanks can be used to store either freshwater supplies or marine toilet waste. Tanks are molded from rigid FDA approved linear polyethylene which meets the CFR 177.1520 criteria. Heavier wall thickness for strength and a 3" inspection port on larger capacity tanks.

Each tank features standard NPT (tapered) fill, drain, and vent openings. Polyethylene construction ensures that the tank will not emit foul odors when used as black water holding tank. Designed for waste or water holding, and available in capacities from 4 to 76 gallons. Translucent design enables visual tank level readings.

Nice fit, good construction
By Twinspire from Baltimore MD

Used as our waste tank, great with the three outlets to use for installing a macerator pump as well as a deck pump out line. We were able to even install a vent line with absolutely no problem at all. We had to use some adapters to get the size down to the one we needed but it all worked out very well, this was a well designed tank, very durable, meets USCG recommendations as well as this liveaboards, I installed it in two days with the first day being dedicated to making a custom mount for it as close to our bilge as I could get it.

Bottom Line Yes, I would recommend to a friend

Exactly what I expected - QUALITY!
By Purebredirish from Minnesota

I am new to house boating and am replacing my marine head by myself. Yes, I'm a woman! So far I have nothing but positive things to say about this product. Easy to install. Most importantly, I'm confident that I have chosen the right product. And when you're talking "sewage holding tanks," confidence is paramount!

Bottom Line Yes, I would recommend to a friend

Excellent waste tanks - very rugged
By Delbert from Merritt Island, FL

Moeller makes a line of superior holding tanks. I bought one- installed it and have been very satisfied. Naturally, I used new heavy duty white hoses, clamps and fittings. Leak free and odor free. The tank is the key component. Don't skimp here.

Bottom Line Yes, I would recommend to a friend
