Sewer connection repair 64 ambassador

I have a before and after picture of my sewer connection on the back of my ambassador. We were using the original caps and sewer connection. They always leaked and were a source of perpetual frustration. Finally one of the prongs on the male side of the connection broke and would no longer hold the Or sewer connection. I had made a decision to cut off all of the prong since they were now worthless and try to put a coupler here and modernize the fittings.

I took a simple extension and hose clamp setup, and with a little bit of gasket material made a great connection/seal. I was quite pleased. However this morn, the clamps had slipped off the original connection.

Anyone know a good cement or product to "lock up" this new connection?

I do see (and have ordered) a 3" termination adapter, but the original sewer tube is about 1/8 shy of 3". Not sure how to cement this "gap"

Sewer connection repair 64 ambassador

OK it is sorted! I would imagine this post could be helpful to anybody experiencing frustrations with older airstream sewer connections. While I would not recommend cutting off the tabs like I did in less you absolutely needed to this seems like an amazing solution:

The original plumbing coming out of the airstream measures 3 1/4 inches outside diameter. The new piece of material is 3 1/2 inches.

The coupling for 3 inch PVC with two hose clamps works great as long as you're not trying to fill the 1/4" little gap -- the hose clamp does that work with the coupling. Tightened up a good bit and Viola!! Updated plumbing!!! I even added in in-line twist on valve so I don't have to deal with the nasty trips from the original valve.

Hope this helps someone else in the future

They make this super hard tape now you can buy at Lowes back in the plumbing section. cures with air or something. I would wrap that a couple times around near the end, and then put the clamp on the other side of that stuff. Maybe sand the plastic a little to make it rough, then use acetone to clean it, then wrap the tape, let it cure, then slip the rubber over that. For using the pvc adapter size issue, you could try ABS grind to slurry it in, or I bought 1/8 plastic abs weld rod. You could tape an end on, the wrap it using a heat gun to make it plyable. Then, abs cement to fill the gaps, then abs again for the finish fit. If tight, you could sand it.
