Bathroom floor is flooded but the tanks aren't full

Hmm..well, my monitors are telling me the tanks (both black and grey) are only 1/2 full..wouldn't they be showing as full if this was a leaking issue?

Do you have your hose connected to a shore water source? If you have a water filter, check under the sink and make sure it is not leaking. I had a similar problem. Make sure you also don't have a secondary water filter under the bathroom sink. The pressure of the water coming in caused a very small leak in the water filter, which overnight, filled up the bottom of my kitchen cabinet. Yours may be doing the same thing, and leaking over to the bathroom floor. The tanks are normally under the floor, so you shouldn't have a leak above them. Also check to make sure your water pump is not on and perhaps leaking.

I just had an issue where the flushing mechanism was broken and leaked water each time I flushed. Check the back of the toilet where the water goes into the bowl, and scope the whole mechanism to see if it is leaking.

Where is water coming from?

How do you know tanks aren't full.........because level monitor doesn't show full?

Water is either leaking from a fitting under sink, leaking from toilet water valve, coming up thru shower drain, coming up thru toilet and leaking from ceiling exhaust fan if heavy raining is going on.

Locate where water is coming from.....then you can figure out how to stop/fix.

black, grey or both?
