How to Fix a Leaky Bathroom Sink
Due to the myriad of connections, there are several places where a bathroom sink might leak. Fortunately, all are relatively quick fixes. Even the ones that might seem likea big project are often fixed with a simple twist of the wrist.
So what we are going to do is shore up all the usual suspects/ problem areas.
Before you get to work, you should turn off the water supply.
If your leak is coming from under the handle, take a knife and gently pry the cap off the top ofthe handle. This should expose a screw that keeps the handle in place. Undo the screw and then lift the handle off. You should find a valve underneath; use a wrench to tighten the valve.
If your faucet is leaking from the base, you will either have to:
1) tighten the faucet to the sink top by using a basin wrench to tighten the nuts on the faucet’s stems located underneath the sink. This will be the case with faucets that are not designed to swivel, and have the handles and faucet mounted on one piece.
2) If the faucet is independent of the handles and designed to swivel from side to side, you will probably be able to have to start by removing the ring that screws onto the base of the faucet and into the base on the sink top. You can start the process with a wrench and then finish twisting the ring off with your hands. Once you have removed the ring, you should be able to jiggle and slide the faucet stem out of the sink top.
Check the rubber O-ring on the base of the faucet stem; if it is worn or broken it needs to be replaced. If this is not the problem, use a Brillo pad to scrub the inside of the faucet, and the area where it meets and slides into the base on the sink top. This should clean off any buildup. Then, you are ready to put your faucet back together, tightening every connection snuggly.
If your faucet is dripping, you should try both procedures explained above. If your faucet is still dripping after tightening the handles and cleaning out the faucet head, your problem is probably the gasket.
The gasket can befound inside the faucet head, the removable piece at the very end of the faucet, where the water comes out. The gasket looks like a flat, black rubber donut. You can find a replacement at the hardware store. Before screwing the top back into the faucet, scrub the inside and the area where it meets the faucet. You probably want to use a wrench to tighten the cap back on; the slightest gap will cause a leak.
