Waste plumbing

[Fdnavy]

I have a 2016 264bhw. This weekend I broke my grey pipe and the black pipe came free of the thankfully empty tank. I think when pulling out in the dark a caught it on the fire ring. I was left with my valves and discharge port sitting on the ground. Undamaged other than a broken grey pipe. I am planning on fixing my self. I am going to replace a section of the grey pipe and use nohub connectors will this work or should I use abs fittings and glue? I do have a couple of questions. First the pipe into the black tank just seems to be a friction fit with a hose clamp. Is this correct? Should I use silicone or something like that to help seal it? Next is there supposed to be a pipe hanger holding the valve assembly to the frame? I am assuming there should be one someplace. Thanks in advance.

I believe you are referring to what i call Fernco fittings. I would not use them. I would cut it apart as needed and replace with abs glued fittings.

I would like to see picture of the black pipe fitting with a hose clamp. That does not sound right.
