I just found the cabinet underneath my bathroom sink to be completely soaked and this is the second time its happened, first time was a couple months ago. After first time, I shut off both valves and checked all the fittings and nothing seemed to be leaking. I turned the water back on and everything was fine. However, today I came to find the same thing happen. I've shut the water off again at this point, but I'm guessing none of the fittings have a normal. Could there be some sort of back up in the pipes?? I'm in Ohio so it is fairly cold right now and was also a couple months ago. Possible that something is freezing slightly and backing up the system? I also have young children who could have clogged it with something. Please help
If its periodic it could well be the waste pipe or trap
yea if it's periodic it prolly ran down the faucet sides from splashing. run some caulk around the base of it & see if that changes anything.
Hi, Jeholman. I have to suspect the big pipes under the sink, the drain lines. But let's look at the whole thing. Take out any and all stuff in the cabinet, get a flashlight, turn on the faucet full-blast, and have a look for leaks. Feel free to poke and prod things while this is happening, as it may disclose a weak or loose fitting. Go for any found. Also look for leaks where there shouldn't be any with good parts - like just behind the handle on the shut-off valves (non-repairable, just replace). Finally, with kids, it may be possible that enough water has been splashed up top, around the faucet base or the edge of the sink, to have leaked down into the cabinet, even with connections underneath OK. Just be thorough, and you'll find it.
