I have a bulge in my kitchen floor, I first noticed it about two years ago. It is about a foot in diameter and seems to spreading in one direction. It not soft and spongy, it is hard I can jump up and down on it
without any give. I tried tracing water lines and as near as I can figure there isn't any there ( I could be wrong). However, the heating ducts run through there and the floor gets warm there when ever I run the furnace, could that be the problem/connection. It will be a major project to tear up the floor to see what the problem is. Any thoughts?

Can't discount water as it could be coming from somewhere else. Turn on the pump and see if it runs over an extended time period But it could be rain. Could be under a top hard layer. Can you view frame members etc from underneath?

Maybe Jimmy Hoffa?


That is the only thing I can think of. Is there any way you can check it out from underneath? Maybe remove the heat ducting to get a better view of the problem area?

I had the exact same problem on my Coachman that got progressively worse (bump/hump kept getting bigger). Lucky for me I have a good freind that owns a carpet cleaning/repair business and has a Master's Certification. We pulled up the carpet, which was the BIGGEST part/PITA of the job. As the hump had gotten quite bad we had to pull it back all the way to the couch and remove the passengers seat and pull that area back also. We then cut the plwood where the bulge was and unscrewed enough to look underneith it and there were a couple small holes that must of let enough moisture into expend the wood although there was no VISIBLE damage. We filled those holes and one guy stood on the now cut piece and we screwed it in (using los of screws), same with the other half. Then sealed the seams with liquid nails and it's been great for two years now.
I was certainly lucky to have my freind help me, if I'd of taken it in I'm sure it would of been major $$$$'s. The wood part was easy but the carpet sure took a pro. Good Luck hope this helps.

Captain I don't like saying this but your going to have to pull up the carpet or remove tile and take a look. During the winter is a good time to do it! Sorry and Good Luck!

Have to agree with J-Rooster. My suspicion might also be the wood expanding because of moisture. But you'll never really know unless you pull out the carpet and have a look.

Hi All.

Not knocking you down. But wonder why have you have waited 2 years to post for help now?. If it would have been our Motorhome, I would have found the problem when first noticed.

Kind of sounds like you do have a small leak of some kind, somewhere. As it has got larger over time, and is heading in one direction. That sounds kind of exactely like a leak would do over time if left unchecked.

As already stated, a water leak of any kind could be coming from almost any where. As water can easily travel over distances where you wouldn't even think possible. If its not a water line leakiing some where, then you probably have a roof leak some where and its traveling. Or maybe leaks from under the Motorhome and mositure is enterning when driveing in the rain.

Is your Motorhome covered in the winter time, or in a RV Port or just stored outside in the weather?. It might be time to reseal everything on your Roof.

Also, check as mentioned, if your water pump runs at anytime when no water is truned on. A sure sing of a problem in your water system. I wouldn't stop until I did evertyhing that I could do to find it.

After re-sealing the roof, and checking for any leaks inside of your Motorhome. If you still can't find it, maybe you should have a pressure test done to find any leaks that you might have and just can't find on your own. It just may be time for an RV Tech.

We wish you good luck and hope its not to big of a job or to expensive to repair. Good Luck. Happy Travels. Dan & Jill
