Valterra Bladex 3" waste valve
I have to replace the dump valve for my black tank. It looks like a fairly simple job. There are 4 bolts keeping it in place. I have a new one but the problem is the 2 rubber seals that came with it. ...

"Caryite...So here's my question:
All of the Valterra and YouTube videos online show the seals as being mounted on the outside pipes on each side and THEN sliding the valve into place, not having the seals inside of the valve itself. That seems to ensure the valve is fully around the new pipes on each side and there's nothing that isn't fully around them and being crimped or not fully circular. The problem is this is nearly impossible in having the seals move once I put the valve in. I'm at the point I'm considering putting some minor non-permanent glue on the seals to the outside pipes (Elmers to keep it in place?) that will allow them to stay in place."
You will be mounting the seals onto the valve assemble then sliding that into place and fitting the bolts/nuts. I would NOT suggest adding any glue. If you are worried about slippage, perhaps a dab of Vaseline. But that seal just sits right in the valve assembly.
