Tourmaster - plumbing question

[Kate P]

I had a valve replaced in the mid cabin toilet. Shortly after that, as a result, or by coincidence, I noticed a buzzing sound from behind the toilet (which is over the hot water heater) whenever hot water was turned on anywhere in the coach. I had someone check it out and they replaced the check valve. I still had the sound. Now, it appears that I have water seeping in under the mid cabin shower (yes, i have two showers in this coach). But, I have no idea of where it is coming from. Does anyone have any ideas???

It could be several things, but I had the same problem, but I sealed it right away. On mine it was that the caulking where the shower door meets the shower body, the caulking had cracked and when taking a shower, water was seeping in through there. I bought a small tube of caulking and resealed it. No more water seepage.

But it could also be the shower drain seal, but I doubt that.
