The most common thing we find is corroded O-rings, gaskets or valve seats that cause faucets to leak. Together, these components are what hold back the water until the faucet is opened, so if one of them is corroded, you’ll get a leaky, dripping faucet! To stop a faucet leak, shut off the water to the sink and open the faucet to let the water drain out. Next, use an Allen key or screw driver to remove the faucet handle. If it has a nut holding the internal parts in place, check to see if that’s loose – tightening it with pliers may be enough to stop the leak! If not, remove the nut and disassemble the faucet (just make sure you can put it back together again!). If the faucet contains a cartridge, don’t take that apart – just replace it with a new one.
Inspect all the components of your faucet – you should see a washers, O-rings or seals and possibly springs – and figure out exactly what you need to replace. Find the precise parts at a hardware store and put the faucet back together. If all goes well, your faucet should be back to normal. If not, call Len The Plumber for faucet repair!
