Hi all. I'm back with another 5th wheel doozy. First of all, a big thanks to everyone who helped with my electrical questions on my newer trailer. Good luck with this one.

This is an older model trailer. 82' 22ft Sportking. It was free from a family member. We started restoring it when we noticed the freshwater tank is leaking. From where we aren't sure. before we started the restoration we used it regularly without issues. When we found water damage in the roof in the corners we decided to restore. That's when we got the new trailer. Anyway....the water tank was always filled once we got to our destination. We never filled it at home. One of our kids stayed in there for a bit and I hooked up the hose to the tank inlet fill and left it on. I was told I should have had a regulator on it because the camper floor became a puddle.

Pretty sure its the tank....but from where....I don't know. Here's the kicker.....it was installed and then the counters and kitchen area were installed over it. So it looks as if I'll have to tear all that out to get to the tank to see if it's leaking at a top connector or what....

Thoughts?

Typically tanks are one of the first items installed. Usually their under the floor. But if yours is above the floor then your only choice is to start taking things apart. Assume you will find black mold so work accordingly.

Could also be plumbed with water pipe, and finally rusted thru........my folks trailer did that, and I redid it all with Pex....

450Donn: Yeah....what's what I figured just by looking where it lay. Was hoping to not rip out the kitchen. The wood is in great shape and has a classic vintage look. It would be a shame to ruin.

As another option, just get a couple of 2 gallon water jugs to use. In years past for a quick camping trip we would use the jugs instead of de-winterizing the RV water system. Keep a jug in the bathroom to flush the toilet and kitchen for dishes.

I've had trailers where the fresh water tank was inside sitting on the floor so understand why the leak is inside. But before you do anything make sure the leak is not on the drain side of things, like a loose P-trap. Second, since you left the hose running to fill the tank and the fill inlet is likely just above the tank, you should check that as well. Due to age, the fill hose or the exterior fill port could be cracked or just a loose hose clamp on either the fill hose or the small vent hose.

Otherwise, if you are sure it is the tank, you should still be able to remove the cabinet w/o destroying it. Disconnect all the water and drain lines to the sink, unscrew the countertop from the base, then unscrew the base from the wall, floor and adjacent cabinet.

Grindstone01: Thanks but going for a permanent fix.

Dayle1: The water hadn't been used in the trailer. I connected the hose and left it on at the fill spout. I can only assume it over filled or busted a line out. I won't know until I get dig into this.

That was my point, the exterior fill spout could be cracked. But most likely just a loose vent hose or fill hose. The rubber looses its compression and clamps get loose, then the weight of water in the hose pulls it off the fitting.
