Bathroom floor is flooded but the tanks aren't full

[k8devin]

I have a 2003 Chinook Concourse and I'm distressed that my bathroom floor is flooded but my tanks aren't full...they're maybe half full, so they shouldn't be overflowing. Could this be a clog? And how do I get rid of it?

To the original poster _ although I have been guilty of this myself a few times in the past it could really be helpful to others if you would respond to the advice given. Namely, what did you find out about where the leak came from and what you did to fix it. This is especially helpful when someone else has a similar problem and does a search to look for help. Obviously a leak or standing water in your bathroom could be a very serious problem which needs urgent attention.

Even if your problem has not yet been solved someone else can then offer more advice if necessary. Good luck and let us know.

K8devin must have found the problem and/or won't bother to respond.

Where is the water coming from?

k8devin, even if the tanks are empty, when you are hooked up to a water source, in most motorhomes, it bypasses the tanks and the water flows directly to your faucets. The tanks are only filled from the fill point outside the motorhome. This is where you have a small door that you unlock and insert the end of the water hose and let water flow in until you determine the tanks is full. Since you did not say if you are indeed connected via a hose to a water source like a spigot, I have to assume that is what might be causing the leak because it would create a constant flow of water into the motorhome, which would occur irrespective of whether the tanks are empty, or half empty, or full.

I think most newer MHs have a valve that switches to fill the tank and the hookup is the same position for everything. I haven't had a separate spot for filling from a hose since my '76 Fireball.

Not true...think it depends on the manufacturer....ours has two sepearte connection points on opposite sides of the rv.

HEY OP.........

Find the source of leak?

I have the same arrangement. I use a 45" long flexible plastic tubing, that I attach to my hose, and push it all the way into my freshwater tank. I can fill it at full flow.

Bobbo, if you only have a gravity fill, how do you hook up to a water source when at a campground? Do you stand there and hold the hose each and every time you have to fill the tank? Kind of tedious, I would think! On my 2008 Tioga, and on a 1994 class C I had, both had gravity fill spouts, plus a hose coupler. That is why the sell the pressure regulators, so you can leave the hose connected to the water source.

When I said "And yet my 2007 Winnebago has a gravity fill opening, but no way to fill from the shore water inlet", I assumed that it implied that I HAD a shore water inlet.

Yes, it is time to engage your semi automatic "leak detection system". :B Disconnect from city water and turn on the pump.

BTW, the toilet water valve is one of the weakest links IF you have subjected your unit to freezing temperatures without winterizing.

Like others have said you have several possible sources of flooding. First thing I would do is flush the toilet with clean water and if the black tank is full you should see water "backing out" of the toilet. The toilet is sealed up so unless water is coming out of the top of the toilet then you should not have a leak there. After that I would start checking all the plumbing under the bathroom sink to check for loose connections, busted pipes, etc. Again if the tanks were overflowing you should see standing water in the sink or shower. Sounds more like a plumbing problem than a tank problem. Let us know what you find.

[Bordercollie]

Look down into toilet with flush valve open to verify fullness of black water tank as recommended. LED indicators may be defective or just way off, if covered up by waste stuff. Investigate carefully and report back about source of water so you can get useful recommendation on fixes.

My 2015 Winnebago View Profile has both a gravity fill for the fresh water tank along with the valve to fill it while it is hooked to my city water hookup. I would think Bobbo has the same setup as I do on mine.

To the OP, I would take my rig to a dump site and empty both the black and grey tanks before I tackled anything else. The readings on tank monitors are known to be off especially after a rig has been used for a period of time. At best they are somewhat accurate when new.

Keep it simple. Open the flush valve and look inside (flashlight?). It should be obvious if the level of the black tank is too high. More than likely though, the water connection on the toilet has worked loose with time and is leaking (or the sink faucet nearby). Not an unusual occurrence.
