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

Through a comedy of errors, I 'tore' the drains off from my holding tanks...THE BEST NEWS is that I was acting as one of those people NOT using the camper restroom for big potty! (I know folks are sometimes over the top about that, but there's no foul for a quick trip and one person to 'be tough' and go to the campground restroom and save the time of dumping)

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).

Quick question- when I put it all back, is there a 'sealing substance' I should put in the joint? Pipe thread putty? Sink drain putty? Some crazy special camper material?

  • There should be a black compression gasket on the pipe. The tighter you tighten the flange nut, the more the washer compresses and holds the inner pipe. Standard plumbing fare.
  • 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?
