Flooding under bathroom floor

[nettepdx]

the trailer: 1975 Land Yacht, rear bath, 25'.
the problem: water under floor - a lot!

no leak from toilet or sink.

due to water problems in the park the pipes in the trailer sometimes get filled with air and it feels and sounds as if the whole trailer is coming apart until all the air is blown out. could all this rattling have shaken a pipe loose? it seems that the water under the floor happened after i showered. could a drain pipe have jiggled free?

some nice guy from the park is going to take a look at it through the access panel under the trailer but i'm afraid, very afraid. and i'm in mexico so can't run out to an RV parts store.

please, someone calm my beating heart.

Just a thought. A few years back on my 1976 Sovereign center bath. I had a leak coming out the bottom of the trailer about where the bath area was. Like yours it really leaked when the shower was running but also when the kitchen faucet was on. Turn everything off no leaks. I searched for a busted water line but could not find anything. So I took off a strip of wood at the bottom of the shower door that covered an opening from the lip of the shower pan to the floor. I could then see under the shower. What had happened over time is that the shower drain line had come loose where it connected with the main drain line before the P-Trap. The only thing holding it was a pipe clamp that had come loose. I was able to reconnect and tighten the clamp and no more leak. The reason it leaked when the kitchen faucet was on is that the drain line for the kitchen sink connected in this area as well. I know you have a rear bath but check under the tub when the tub drain connects. Good luck.

Don, you may've nailed it. manuel checked through the panel under the trailer and said that the shower drain was the problem. he thinks he fixed it with silicone sealant. we shall see. at least now i know how to get to it should it keep leaking. and i wondered why it also seemed to ooze when i turned on the kitchen sink. so that wasn't my imagination! many thanks...
