A leaking faucet is an annoyance that produces constant drips of water; if it goes unchecked for too long, it can result in even more serious inconveniences like higher water bills and overflows that damage surrounding walls and flooring. To prevent any of these possibilities, always address a leak sooner rather than later. Below are some of the most common causes behind this issue.

Why Do Faucets Leak? 

1. Worn Cartridge

As their name implies, cartridge faucets contain a metal cartridge that seals the spout and controls the flow of water. Regular use and water sediment buildup inside the cartridge can cause it to become less effective, which in turn produces leaks. Like a damaged O-ring, a worn cartridge is usually a minor repair, but it's best to consult a plumbing professional to ensure you switch out the cartridge with the correct replacement.

2. Damaged O-Ring

The O-ring is a small rubber disc located near the base of the spout where it screws into the sink or the shower wall. Its primary purpose is to prevent fluid from passing through when the faucet is turned off, so this is often the first place to check if you have a leak. Over time, the O-ring can wear out or break. O-ring issues typically cause leaks around the base of the spout or near the handles.

3. Washer Issues

The washer is situated above the valve seat under the stem of the faucet. The washer and the valve seat move against one another when the taps are turned on and off. Washers are also essential in stopping the flow of water. Since they are often made of either rubber or plastic, washers can erode with long-term use of the faucet, or if they aren't installed properly, they won't be able to fully stop water flow. In either case, leaks will result.
