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.

It says for the 19 gal waste tank, the holes are drilled. It doesn't say if it comes with the fittings?
Yes, it does come with the fittings.
It does not come with any fittings.
The tank doesn't come with fittings, I provided the needed fittings for the install.
Yes it comes with fittings some you may need some you may not need depends on what you have already.
comes with fittings
No fittings come with it. Just plastic cap plugs.

hidoes anyone know where the original holding tanks were located and capacity on chris craft 38 commander express ?thank you
Hi Rob G, I don't know that boat specifically, but I owned a 1976 Chris Craft 32 express, and it was located on a plywood platform built over the top of the rudders in the stern area. I used the 13 gallon holding tank from Moeller, and was pleased with the fit and suitability. I wouldn't say that's a great location for a holding tank, in case you need to access the steering mechanism - it was a bit tricky to reach things without removing the tank first.. . . nevertheless, that was my experience. Someone else may know your boat better.
I believe they were under the bench seat. Ask on the Chris craft commander club or the Chris craft commander forum. They have a wealth of information.
I don't know anything about a Chris Craft.
Does the 13 gallon come with a 3" clean out?
my 25 gallon came with all the fittings needed.
I HAVE THE 77 GALLON TANK, IT WAS 3", NO IDEA ON THE 13 GALLON.SORRY
That tank does not come with a clean out.
the intake and discharge openings, what size are they?
i AM NOT SURE BUT THE ONE MATCHED EXACTLY WHAT I TOOK OFF, THE OTHER REQUIRED AN ADAPTER EASILY FOUND AT HOME DEPOT OR WEST MARINE. COMMON THREADS, ADAPTED VERY EASILY. NICE TANK.
1 1/2 in. IPS
Inlet and pump out are 1 1/2" the vent is 1/2"
how much does the the 9 or the 13 gallons tanks weight ? thanks !
I can't tell you exact weight but I bought the 30 gallon and it weighs next to nothing. Small children could play catch with it. That's how light it is
I bought the 13 gallon tank from Jamestown in June, and the shipping weight was 16.4 lbs. So, I'm guessing the tank itself would be around 15. Hope that helps.
Well I had 30 gallon tanks so not sure of the smaller one's, however they are not heavy ( a relative term) and easy to move around.
what size holding tank do you recommend for 40 ft sailboat?
IMO, it depends on a couple of factors: how large and what shape is the area that can hold your tank? This may limit the tank you get. Also, how do you intend to use it - as a liveaboard with frequent use? Or a rare, occasional head use when other facilities are unavailable? If liveaboard, go as large as will fit. I have a 30 ft motor yacht and bought the 13 gallon one - we use the boat almost every weekend. Hope that helps.
I see the intake, outlet and vent ports on this tank. Ho hard would it be to install a monitoring sensor?
Well there is a large port on the top 4" I think on mine. I was replacing a tank with sensor so I used the 4" opening and pvc fitting to make it work with my system. Hope this helps.
I would use one of the external foil systems, like Profile .float type Monitors don't work well over the long term
Very simple, I used the "Sensa Tank" that goes on the outside. They stick on and have a very nice panel to monitor levels of the grey water and fresh water levels. Very nice and easy and surprisingly inexpensive. Very happy with all of it. I did my boat and my brothers in about 4 hours. Hope this helps.
MOE 041230*****28"x23"x11 1/2" I want to lay this tank on its side so that the 11 1/2 " is its base . Will the tank properly empty in this position ?
I stood it on end with the outlets pointing up and added a pickup tube to the pump out waste discharge opening and it works fine ... That's not quite what you asked but hope it helps ...
If you can position one of 1 1/2 ports at the bottom it should empty fairly well
no it will not it has to be mounted the way it is pictured with the vent on top
The outlets are centered in the tank so turning it on the "side" would not allow the larger opening to drain the last 3rd of the tank if it's used for waste. Now if you're using it for water the smaller vent opening would get most of the water out. Dan
Short answer no. The outlet hole would then only allow half of the waste to be dumped. If you had a macerator pump you could try to put a pick up hose on the inside, however this may prove to be very difficult to rig up permanently.
What is the thickness of the walls of the tank? I've read there a thin-walled and thick-walled tanks and obviously the thick ones are better....
The walls of the tank were thick, at least 1/4 inch and very durable.
I weigh 147# and I'm able to stand on the tank with barely noticeable sagging. It is plenty thick for whatever it's intended use.
The tank thickness is more than adequate for holding waste. I bought a 40 gal and it was easy to install. Just make sure you measure your space and if you have to make one out of cardboard box to see if you can maneuver it into position.
The tank I bought was relatively small, but seemed to have a wall thickness of about 1/4". I was not able to measure this as I did not have to drill any holes.
how do you install these?
I had to measure the space where the old tank was installed and purchase the tank that fit this space. I used existing strapping and mounted the tank in the aft enging compartment.
I fiberglassed two wooden cleats to the hull and centerboard trunk on a sailboat and installed a 17 gallon tank using stainless steel straps across the top and front of the tank...works great.
It fits and works great
a replacement holding tank on a house boat. Works great.
Perfect for a small houseboat, except louder than expected
We put this in our houseboat. It was easy to install. The instructions included were helpful and covered everything we needed.
Nice heavy weight molding...
Nice fit, good construction
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.
Great product, and customer service was above and beyond. Shipped quickly.
Exactly what I expected - QUALITY!
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!
Nice solid tank
This is a solid tank with good placement of the fittings and no problems at all.
Excellent waste tanks - very rugged
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.
