Mysterious Bathtub Water

hurly23 · 09-22-2011, 10:30 PM

Ok, So I went camping this last weekend, and on our way there we had the tanks empty (So to save on weight through the 5000 ft pass). Well on the way back we had left about half a tank in the fresh water tank, just in case of bathroom breaks and what not. None in the grey or black tanks. Anyways, we get back and I find my bathtub is 1/4 of the way filled with water. We didnt use the shower at all that weekend (stinky people i know) so it was not accidently left on, and the toilet as well had filled nearly all the way up. I have no idea how this happened. Has anyone else ever encountered anything of the sort? We are going again this weekend and i am going to leave water in fresh tank both ways to see if it happens again. The only thing i could think for the tub was that when we left the campsite and drove to the dump station there was a significant incline and maybe the water backed up into it or something. I didnt check after i had dumped. But that doesnt explain the toilet. Thanx for input!!

Could you have had enough change in altitude from where you last used any water to where your home is to have caused the air in the water tank to expand causing water to leak out? I once opened and resealed a water bottle while flying and then noticed if was pressurized when we landed.

FYI It's helpful if you put the year and type of RV in your signiture so you can get more detailed info. Just go to "user cp" in the top left corner of any irv2 page and then click on signiture to add yours. That way you won't have to type it in every post.

Turn off your water pump while traveling.
I had mine on and a bar of soap fell down and hit the water handle in the shower and turned on the water. Pumped the fresh water tank empty and flooded the trailer.
The toilet is a mystery though.

Let us know what you find.

Prolly a dumb question.. but do you have TWO grey water tanks and possibly one was not drained? On my last RV we had a Black, Grey and Kitchen tank.

I only have one grey tank. I thought I changed my signature. Maybe doesn't do signature frm phone. But yes I did change altitude significantly frm 2k-5k ft. That may be the case. Rig is keystone sprinter 27ft tt

I had the same thing happen to me once and could never figure it out. Of all the miles we put on it never happened before or after..... go figure.....

I would definitely sanitize the fresh water system, just in case that mysterious water flow was able to travel in both directions.

Okmunky had it right. Change in pressure due to altitude expanded the air in the water lines and made water come out.

Well, that can't be true for mine. I was in FL the whole time.... Stopped to get fuel and the tub was filled with water and the toilet was almost over flowing...

Im pretty sure i figured it out. I overflowed the grey tank, since i didnt check the tub before i emptied the tank. Not sure how other tanks work, but when mine is full it fill back into the bathtub. Not sure about the toilet, but im pretty sure thats how the tub got water into it. It happened again this weekend. Except i caught it early thank god.
