A leaky faucet, if left unrepaired, can become a major problem beyond the money it’s costing you on your water bill. A faucet dripping can be indicative of a larger problem that could cost you hundreds of dollars.
The location of the water leak will give you a good idea of what the problem may be.
You may have a loose or damaged O-ring, which is a small rubber ring around the valve stem. If your O-ring is the problem, you may be seeing leakage from beneath your faucet’s handle. If this is the case, a simple O-ring replacement is all that you need to do.
If your faucet is dripping after it is shut off, this may be indicative of a loose or damaged seat washer. The seat washer screw can become loose from repeated use, causing the faucet to drip or chatter. Newer faucets may have plastic valve cartridges that occasionally need to be replaced. The seats for these newer faucets are typically made of plastic and have springs. These may need to be replaced as well.
A corroded valve seat may also be the issue. The valve seat is the connection in the compression mechanism that the valve / cartridge seats against. The older seats were made of brass and could be resurfaced and made new again. but that’s not the case with the new plastic seats. You have to replace the entire unit.
Water leaking from around the kitchen faucet spout base is a very common problem that requires removing the spout and replacing usually the two O-rings. Often, the faucet spout is pitted too badly from hard water or a neglected leak and the new O-rings won’t be able to seal. In this case, typically it's time to replace the faucet. However, if it is not too badly pitted, new O-ring should resolve your leak. Plumbers grease should be rubbed onto the O-rings before sliding the faucet back over the base. This is also a repair that may require professional assistance to get right.
If you have a disc cartridge faucet, the inlet and outlet seals may have become worn out. Cleaning water sediment from the faucet seals is one of many maintenance actions a plumber will take during a scheduled visit.
