Water under linoleum

As a starting point, what have you done so far to find the leak?

Do you ever noticed the water pump randomly turning on for a second or so without having opened any faucets?

Shower or bathtub drain. Bet you find it there. Leaking and spreading where the pipes come through the floor. Check there. I bet there is nothing wrong with your water pipes.

I would first check the P trap under the shower. The RV flexes, the shower pan flexes, it is probably the most common plumbing joint to loosen in an RV.

I also had a problem with water leaking from the refrigerator. It's easy for the water to get under the tile from there.

Good luck!

Where exactly is the water beneath the linoleum? Kitchen, bath, toilet area?????

Thanks to everyone for your ideas on our leak. We have checked under all the cabinets and drawers on the curb side of the coach. Did find a leak under the sink last night - repair guy coming on Monday. Hope that is it! P trap is dry. The overflow drain from the refrigerator defrost has been rerouted so that it now drains outside rather than in the little cup provided but haven't seen any water on the ground outside.
We are hooked to city water so water pump not coming on. The water has been mostly in the hall between the washer/dryer and the bathroom. Just had some on the top of the floor in the kitchen, thus found the leak under the sink. I will tell the repair guy all of your ideas. Is this something that he should be able to fix? We were told if we have to take the floor up we may have to go to the factory -- really hoping its not that serious!

If your floor is still solid, and not spongy, there's no reason to take it up. If the floor is particle board, it may come apart if it stays wet long enough. If you can get everything dried out, you might be just fine. There again, if the floor is not spongy or soft, give it time to dry completely. Even if it's spongy under the cabinets, as long as you are able to walk or stand in the middle on solid, you can probably get away with that. Trying to fix may do more damage than just leaving it the way it is. AND, even if the area you walk on is a little spongy, even that's OK, as long as it's not getting softer and softer and crumbling. I'd wait and see how everything dries out before jumping in and tearing the floor out when you may not need to.

If you need to remove some of the floor around the various drains, I'd just cut out only enough to open a hole to make it easier to work, and plan on replacing. Especially if it's under a cabinet. Personally, I think your floor is fine.

Turn the outside water off and run off the pump only turning the pump on when you need water. No use risking leaking water all night making matters worse. If you leave the water pump on and it runs with no tap open you will know you have a leak in the pressure side of the water system

This is where I found my leak. Spilled out of the catch tray
