Water damage under shower.

[Baseballwife02]

Hi all! My husband and I just purchased a 2019 Forest River Salem 32 rlds. I was doing dishes and heard a noise.. ran to the bathroom and water was coming from under the shower. Turned everything off and opened the little panel to find my WORST nightmare. Water damage. There’s a hole cut under the subfloor that’s under the shower that apparently has been collecting water from longgggg before it was ours. I don’t even know where to begin with replacing this. Any suggestions or help would be appreciated. This is our first RV and we’re only 2 weeks in.

Also to add... I checked all closets, cabinets, floors around the area and the subfloor does not look to be damaged at all in those areas. Just the area that was cut under the shower.

If water isn't coming from that area anytime the supply side is pressurized, it is the drain side. You will have to check the drainage pipes and all connections. Don't forget to examine the traps closely. If they didn't get antifreeze in them they could have cracked.

RV plumbing leaks are common, easily fixable and usually show up before much damage is done.

Pressurize the system, run the shower and find the leak.

I'd also check all fittings and hand tighten, only takes a few minutes.

In the future, listen to your water pump.
If it cycles without water demand, there's likely a leak somewhere.

And yes, when the grey tank reaches capacity, it shows up in the shower 1st.

^This. Then dry it out. I have had several plumbing leaks for various reasons that caused no lasting damage. The trick is to get the leak stopped first, then access the damage.
Good luck.

Some have the floor hacked out under the shower so bad that there is little support. Then the drain pipes might take the load and crack, ask me how I know. If you can't find the problem, then pull the shower base and do it right.

Don't panic.

It's hard to tell what you mean but, first, fix the leak ! Then dry the floor. If the only place that got wet is under the shower, the shower floor is still firm, and the rest of the camper floor is still solid then I would not worry about it.

But, that's just me. Little things happen. I don't worry about them.

I just had the same issue with my Forest River. Remove the p trap and remove the drain. Then stick a blow dryer into the hole.

Will take a pic of mine. Its drying right now.

My first thought when ever I read this sort of thing is whether the manufacuter used plumbers putty fo rthe drain. If so, it wont last because it is not for use on plastics(sais so on the container). Use only 100% silicone.
I've seen numerous leaks in RV's and homes because of this mistake - often made by professional plumbers.

Sounds like you have some loose compression fittings in the drain line plumbing, pretty typical. I don't thing the Amish craftsmen know how to tighten fittings up. Had the same deal with my new one but I checked all of them before I ever used it. They were all either loose or had inadequate blocking under them or both.

Very typical, what I never buy used, only new but I go over everything before using the first time, I dislike surprises.

X2 on hondapro’s comment. PRONTO!

It’s not clear if you were hooked to city water. Were you using a pressure regulator? This is why I fill the tank and use the pump.

Can you tell where the leak is coming from? You need to do that first before you do any repair.

How long ago did you buy it? Is it still under warranty? If so I would start by contacting the dealer where you bought it. Also you need to get the water dried up asap.
