Water in bathroom floor from toilet??? Help!

[plh869]

Ok...need some help! We have a 2014 FR Wildwood DBUD travel trailer. Last camping season, our bathroom had some water in the floor that seemed to come from our toilet. It’s not a lot of water, just enough to wet the floor. Not flooding or anything like that. The weird thing is, that we mostly emptied our black tank before leaving to come home from each trip, and only leave just enough water in the bowl to cover the seal and a very little in the black tank for the water treatment pod between camping trips. It only leaks when we’re traveling on our way home, never traveling on our way camping or during our camping stay. It’s happened a couple of times. My husband can’t figure out where the water is coming from. We don’t leave enough water in the bowl to splash out on the floor and we close the lid. He even took off the cover to look at the water lines to the toilet and connections, but everything was bone dry. Any suggestions or ideas would be greatly appreciated!!!! We are beyond stumped!!! Thanks!!!

There was just a thread on this exact thing. They did find that the little bit of water in the toilet was splashing out, even though they didn't think it was possible. Try removing all water from the bowl next time and see how it goes.

Is it possible that it's coming from the shower head or the sink? If it's not the toilet, I'd suspect leftover water from the shower head. I'd put a towel around the showerhead and the sink faucet to see if that's the problem.

It's also possible that you've got a leak in the toilet seal and it doesn't show up until you're on the road.

Ah, finally found the previous thread, lots of ideas plus the final outcome.

Mine had a small split from water that froze over the winter. It would spray just a tiny amount against the back wall each flush where you don't notice until enough gathers and becomes visible. Sort of like a high pressure leak in an engine hose. Cheap and pretty easy to replace if you stand on your head a bit...

we had a similar problem. Is there a plastic shroud around the base of the toilet. Ours did and behind the shroud was a large gear clamp gear clamp that attached the bowl to the stand. Carefully tighten the gear clamp and that might stop the leak, at lease it did for us.
See pic on link below, you'll be able to see the gear clamp.

What kind of toilet? If it is a Dometic 300, there is a known problem. They made the bowl in two pieces and water gets between them. Dometic will send you a complete 310 for a small fee if that's the problem.

Since you mention that it happens on the way home, but not outbound, think about this:
On the way outbound the water system is not pressurized.

On the way home, the water system is pressurized; either you were running the pump or hooked up to "city water" before you pulled out. There are check valves on both sides that prevent water from "going backwards", so you still have pressure. Now, as you ride along and the trailer bounces, the line flexes and a little water squirts out. So pressurize the system and reach behind the toilet and wiggle the line around gently. You may find a joint that's not quite tight enough, or that the valve is not fully inserted into the toilet, or even a tiny crack in the line or valve. (The toilet valves are known for cracking in freezing weather if they are not fully winterized.)

Be sure to let us know what you find.

Have several trailers in our rental fleet and have found a couple of the Dometic 300 or 310 toilets to leave into the base between the floor piece and the upper bowl area. Liquid seems to build up due to a leave between the two pieces. My fix has always replace the toilet as trying to fix this has never worked. Pain the butt to fix as usually removing the toilet with the issue is a stomach turning event due to the bolts being rusted from the moisture. Once you replace it things are great. The last one I did I literally had to split the base with a chisel to remove the bolt on the inboard side...out she came. Cleaned up the mess and replaced with a new Model 300. All good now.

As I get it, the 300s have the two-piece bowl and are prone to leak at the seams. The 310 is a one-piece bowl and does not have this issue. For a while Dometic was giving free upgrades, then switched to a $75 credit towards the price of a 310. 310 is dimensionally equivalent to the 300. As you said, a drop-in fit.
