What Causes Bathroom Sink To Drip

A dripping bathroom sink can be a major annoyance, and it can also lead to water damage if left unchecked. There are a few different possible causes of a dripping sink, so it's important to identify the cause before you attempt to fix it.

The most common cause of a dripping sink is a worn-out washer. The washer is a small rubber or plastic disc that sits between the faucet stem and the valve seat. When the washer is worn out, it can allow water to leak past the valve seat and drip out of the faucet.

Another possible cause of a dripping sink is a damaged O-ring. The O-ring is a small rubber ring that sits between the faucet handle and the faucet body. When the O-ring is damaged, it can allow water to leak around the handle and drip out of the sink.

Finally, a dripping sink can also be caused by a loose or damaged faucet handle. If the handle is loose, it can allow water to leak past the valve seat and drip out of the faucet. If the handle is damaged, it can prevent the valve from closing all the way, which can also lead to a drip.

If you're not sure what's causing your bathroom sink to drip, it's best to call a plumber to take a look. A plumber can quickly identify the cause of the leak and make the necessary repairs.
