Shower drain leaking

[bandmbrown]

Had some water on the bedroom floor so took a look at the most
Likely item ...the shower ....and put a light down the drain. Well, the gasket that connects the surface drain to the drain pipe has spun and there is a huge gap ...thus the wet floor. The surface drain is seated with a nut spun up the drain tubing from the underside
I guess the only solution is to remove the pan. I think I can remove the drain fromthetop by putting pressure or cutting the existing drain...but...can't see how could ever get a permanent seal when replaced with no backing nut.
Anybody got any experience in pan removal...please chime in.
Thanks
Bob

I think I posted my above question before thinking the problem thru. The best approach seems to access the plumbing from the underside. Calling the manufacturer now to find out how...does not appeartobe easy.
Thanks

That is a very short and tight space, and very hard to work. Hmmm.... Does anybody know if maybe there is a product that could be applied to the outside of the drain piping between the shower pan and the coach floor to seal the piping?

Called Fleetwood. Rep said there ia an outside access panel. Found it. Pogo is 100 per cent correct. What Fleetwood thinks is access is a far cry from what I think is access. Panel is located spanning the rear two battery compartments.
Half in one...half in the other. Started removal and it started to rain..so...I'm done today.

Had the same problem on my old Coachman. Had to pull the outside radio panel and reach through a roundabout access. Lucky I have long arms but I did get stuck a couple of times and thought I would need the jawsnof life to get my arm out. Good luck and keep a six-pack in reach.
