Worst Case Scenario - Black Water Tank Leaking

There are repair kits on Amazon, depending on the type of plastic. Some have slapped on eternabond tape for a temp fix. And there is plastic welding. I'd look at the options before buying a new tank, especially if you are thinking of upgrading the unit.

How bad is this?

Oh, it's BAD! ;) Real bad! :D So bad, you REALLY should consider a new camper now! :B I think your old one has seen it's better days and now only doom and gloom are foreshadowed in it's future. :@

So, seize the moment there my friend and just do it! :E

Once is over, you'll so glad you did! :)

Um... about fixing it? um ... I have no idea. :(

Do you know where the tank is leaking? Possibly you can make the repairs without dropping the tank.

I would definitely try to repair the tank before you buy a new one.

Black is probably ABS. Had a leak on my first rig. Used JB Weld and it held for 5 years and still no leak after 5 years

Not sure if you're a dealer trying to get me in to buy? Lol

I have some problems. Black water tank, slide broken, all cabinet doors have needed fixing, no shelves in the closets, don't like the settee and need a couch.

I was thinking of getting a new RV anyway but I'll try the fix in place as soon as I can get into the bottom of the TC and pull it all apart.

Noob question. Are there RVs that have the tanks built in well enough to drive with them full? Truck campers? Class C or B+?

Wow. That's a pretty good result. It's black.

I'll take a look and try the jbweld.

No, not a dealer, just love to see folks get new campers!

A, B, C, TT, and 5er are made to travel with full tanks. But sometimes, folks do report tanks falling off. But it is rare. Unless traveling for boondocking, I think most travel with partial filled tanks. Even though they are suppose to be able to be used full, most folks never trust them with that much weight. I also travel with just minimum water. Just enough to flush the toilet when traveling (5 to 10 gallons of water), and try to always dump the black tank before getting on the road. Never had one fall out on me, hope I never do.

I've heard of folks using JB Weld on ABS plastic and had good success. It's something you might try. But ... if it fails... well... here's your chance to convince the Mrs. it's time for a new camper! :)

Ha ha ha. Thanks for posting in my thread. You turned it from a stinky worry into something fun and entertaining.

Thanks to everyone else as well. JB Weld is my first try. I'll post back with results.

Unfortunately sewage is now all inside the basement and soaked into the insulation. I'm going to have to replace a lot of stuff just to get the stink out.

I do travel for boondocking and don't pull into a campground often so... I travel with full water and let that go to gray and black until they're getting up there then dump. When in the truck, the 50 gallons water tank does fine. Supported by the bed.

REAL men don’t fix no stinking black water tank. REAL men buy a new RV.

Hopefully it works for you. I made 2-3 layers of buildup. It was cracked where the outlet nozzle attaches to the tank. Because of that there was nothing to cut out and replaced. We were on a long trip and parked in a friends yard and I believe that the tanks, nearly full, added stress to that area. On my first unit it looked like my fresh water tank was sagging, I travel with as little water as possible, I added a piece of pipe bolted to the frame. Flattened the ends. Others have used unistrut or solid or perforated angle
