There’s water all over your bathroom. It appears to be the dreaded “leaking pipe under bathroom sink” you’ve Googled so many times. Left alone, it can cause a lot of damage pretty quickly. How do you fix it?

Assessing the Leak

You know a pipe is leaking, but where is the leak and what kind is it? Is it the “leaking pipe under bathroom sink”? Look in the cabinet underneath the sink to see where the water seems to be coming from. Is it the dreaded “leaking pipe under bathroom sink”? If it’s from a pressurized hose, the water will likely be spraying everywhere. However, if it’s from the drain line, the water will instead pool slowly underneath the pipe.

If the water is pooling, look to see where in the cabinet it seems to be centered. If it’s at the back, the problem is probably the connection between the faucet and the hose. If it’s in the center, it may be a leak in the sink-drain assembly. If you can’t see where the drip is, fill the sink with water, let it drain, then watch the pipes underneath.

Fixing the Leak

If water is leaking, a connection is probably loose somewhere. Look wherever you’ve determined the leak to be and see if any of the nuts need to be tightened. If you can’t locate it, check the shut-off valve and tighten it with a wrench. Then check behind the sink, for the connections between the pipes and the faucet. Use pliers to tighten those. They may be difficult to reach.

There may also be a problem with the P-trap. If it’s clogged, you can remove the trap and clean it out with a bottle brush or a piece of wire. If the P-trap is metal, the “leaking pipe under bathroom sink” might be due to corrosion, in which case you’ll have to replace it.

If you still can’t find the problem, or if it turns out to be a more difficult fix, call a plumber.
