Hello, there! Thank you for posting your question concerning the Delta B512LF single-handle centerset lavatory faucet. There are several factors that cause the faucet to leak. But the most common reason is corroded O-rings, gaskets, or valve seats. To stop the faucet from leaking, shut the water supply off and open the faucet to let the water drain out. Inspect all the components of your faucet – you should check for worn-out or broken washers, O-rings or seals, and possibly springs too – and figure out exactly what you need to replace. If all goes well, your faucet should be back to normal. If not, we recommend finding a local plumber to do the repair. We hope this information helps. Should you have further questions, let us know by contacting our customer support specialists at 435-868-4020 or through support@plumberssstock.com.
