23FB Shower Drain Leak

[Rob Edgerton]

Just am noticing water leaking outside only when using the shower. No water inside on the floor showing. Checked the access to the shower valve, all is dry. I suspect the shower drain is leaking. Thoughts or suggestions?

We bought our trailer used, but it must have had a shower leak at some point. An access hole was cut in the belly pan right under the drain and the flange probably just needed to be tightened.

Might be the same as on the 22, since the layouts of the bathroom is similar. Check the caulking at the bottom especially at the left side.

I recently helped fix (in a friend's Airstream with a corner shower) a similar leak a couple of months ago.

The shower drain is connected to the P-trap plumbing with a "swivel adapter" (https://www.menards.com/main/plumbin...4449188850.htm, https://www.rveparts.com/rv-sewer-ab...adapter-1-1-2/)

The swivel adapter uses a rubber ring gasket to provide a watertight seal. The threaded collar of the adapter compresses the rubber and can easily crack due to continuous tension and from supporting the weight of the P-trap and its contained water. After cracking, the joint then leaks out the bottom of the trailer. Rough roads can "help" crack the collar. The swivel adapter is common for RVs, but not in most plumbing supply stores.

We fixed the problem by cutting a hole in the belly pan to access the plumbing. After repair and leak testing, an aluminum patch and pop rivets covered the access hole.

Just had the exact same problem and fixed at our local dealer. They said it just needed a new clamp. Hope yours is as minor

Oddly enough I just fixed ours yesterday. There was an inspection plate where it looked like some was there before. Ours is a Bambi 22FB. It was a nasty job and had to remove the inside shower drain piece just to get to the nut. Nut was split and leaking. Once I replaced the nut and reinstalled everything seems fine. I suspect everything does not line up exactly and may be stressing the connection. However once I got the lay of the land was a half hour job tops. Good luck!

Mine wasn’t a half hour, more like an hour plus a two hour trip to the nearest Home Depot for parts.

Below are pictures of what was there and what I replaced it with. Now if I need to work on it again it can all be done from below without having to take the floor drain out to get things apart. Poor original design in my opinion, and it didn’t leave any room to flex or for slight misalignment.
