I have water pooling in bottom of bathroom sink cupboard

Question

The pool of water is close to drain and water pipes, but cannot find source of water. All connections are tight and have no 'drips' visible. ( This is a Manufactured house, so nothing would surprise me!) Any suggestions will be greatly appreciated!

Susan · Answer

I am by no means an expert, but my father lives in a manufactured home, so I will venture a guess. My first thought is that the seal around the taps or the sink drain are allowing water through. If water is splashed up onto the top of the sink, it might leak into the cabinet. My bet is on the seal around the sink drain or the sink itself. Good luck!

Jim Grossman · Answer

If all else fails just put a bucket below the drip. In a new home it may even be a porous spot in a pipe allowing the water to come thru. Maybe condensation? Try using a fan to totally dry the area and then see where it develops first. If the place is new do you have a warranty?

Dry it, run the water, watch what happens. The idea is to closely identify where it comes from. Then go to a plumbing store (big box store may not have the experienced personnel) or talk to a professional plumber for opinion.

I used to work in maintenance and this was common. All of the above answers except the bucket to catch the water are good. Here is what I have experienced. There is a gasket where the faucet seats to the sink. It could be worn and the overflow water is getting by. If the faucet assembly is old, replace it. Very easy to do. The most common leak occurs when the PVC pipe for the drain gets hit and you don't even notice. Try to tighten all of the joints. Do it by hand only. If you have a metal drain, the very bottom of the trap could have a tiny leak. Replace it with PVC all the way from the sink to the pipe that comes through the wall. If you feel underneath the very bottom of the trap put some pressure against it with your fingers but be sure to have a shallow pan under it because it will surely disintegrate with your touch.

Wrap toilet paper around all of the pipes and fittings, that way you will see the wet spot and be able to find trouble spot

Susan · Answer

We just had the same problem in our kitchen and had no idea as to where the water was coming from. Eventually, we discovered there was leak in a pipe attached to the dishwasher. The water filtered under our wood floor all over the kitchen and flowed into the living room. Once the leak was repaired, our problems were solved. We were afraid the repair would be in the $$thousands of dollars; to our surprise, our total cost was under $200. What a relief!

Ivy · Answer

Newspaper to locate leak. dry out everything and make sure the paper is against the back wall. Turn on water with the drains stopped up, and start watching for drips. If none, open drains, if none seen at this point, start dishwasher and check again. If it only occurs when it rains than it is a vent problem. (roof) That way you can distinguish whether it is clean water or dirty water.

Janice · Answer

The toilet paper test is awesome! You'll learn almost immediately where the leak is and can then take appropriate action. Most hardware stores can advise what parts you need to make the proper repairs once you know where the leak is occurring.
