The connection between the holding tank and the drain...

Yup. Some Canadian campers with a rental came into the store this summer with the dump piping dangling from a pipe hanger. They run over something on the highway and it kicked back. Grabbed a 3 inch flexible coupling from the black pipe shelfs and had them back of the road in a half hour.

I did feel bad for the people on the road behind them.

Years ago I noted a tiny black water drip and tracked it down to the connection I think your referring to - didn't take it apart (tank was full) but did tighten the hose clamp and the drip stopped. I would't be surprised if there was a rubber gasket at the end - but maybe not. Shouldn't be hard to test without gasket and see what happens. I have an older Fleetwood so maybe the same setup?

The true power of a discussion forum... amidst a lot of pure, unfounded, spewed opinions, someone with directly-applicable experience.

Thank you.

There is a standard "hose clamp" around the flange at the end of the tank. The black PVC slipped up in there about an inch, and there is no evidence of glue on the pipe. Same set up on gray and black tanks (different diameters of course).

Camper is a 15 YO Fleetwood Terry. The true bad thing is that it's 27 ft but has the axle over the springs...very little clearance for the drains at the far rear...

AND for the record, this set up has been water tight for 15 years...

Anyway- I was amazed to learn that both the black and gray tank connections were not glued, but 'slip in' and 'hose clamp' and I didn't actually TEAR it off, it simply pulled out (more luck).

That sounds like a standard plumbing fix. Been there seen that! :B

I had the holes on where the valve blade screw in break on the side going to the tank. That pipe and valve holder was one molded piece to the whole tank.

The fix (to my surprise too) is to put a standard residential plumbing fix. They cut the pipe after the tank and before the valve blade holder, added a new piece of pipe with new valve holder and inserted what looks like a rubber sleeve and hose clamps to join the pipe/repair it. NO glue what so ever is needed. And yes it IS water tight.

The previous owner must have done this to both pipes gray and black when maybe he replace the entire y connection.

I would just unscrew hose clamps and re insert your pipes and then put hose clamps back on.

RTV silicone - Wikipedia
https://en.wikipedia.org/wiki/RTV_silicone
RTV Silicone (Room-Temperature-Vulcanizing silicone) is a type of silicone rubber made from a two-component system (base plus curative; A+B) available in a hardness range of very soft to medium--usually from 15 Shore A to 40 Shore.

Ditto on the acronyms; second time I've seen "rtv" used. I give up-what is rtv?

Sorry, I don't do acronyms.

there should be a gum tape around the pipe. if not just use some rtv and slide it in tighten the clamp

I would think they should be glued. I have never heard of an "approved" plastic system that would be just "pushed together". I wonder if you would not being going through this in the first place if it had been glued at the factory?

If it had been glued at the factory, I anticipate it would have broken IN the tank and then I might be SOL....literally.
