Causes for the kitchen sink leaking are various. The following 7 causes are common for the kitchen sink leaking.
1. Leaking faucet
The faucet leaks may be distributed to the worn washers or gaskets. It happens either at the top of the sink or under the counter, which is quite easy to spot. In this circumstances, you usually just need to replace the old washer or gasket.
2. Leaking drainage
The leaking drainage is another common reason for the kitchen sink leaks. Dry putty around the drain or the worn out old drain may lead to drainage leaking. Therefore, you need to replace the reseal drain or change the old drain with a new one.
3. Loose water supply connection
Leakages are most common at connections. It will take some time to spot the leakage point since the connections are mostly hidden inside. Leakage happens if the water supply connection is loose. In this situation, you only need to tighten the loose water supply connection.
4. Corroded valve seat
The valve seat serves as the connection between the spout and the faucet. The accumulated water around the valve seat will cause corrosion to it, which finally leads to the leakage.
5. Damaged O-ring
An O-ring is a screw that holds the faucet handle in place. If the O-ring is damaged, leakage occurs around the faucet.
6. Clogged P-trap
P-trap refers to the curved section of a pipe. This one is also usually placed out of sight, which means it will be less easy to find out right away. The clogged P-trap may cause the leakage problem.
7. Lack of sealing for natural stone sinks
If you have installed a natural stone sink for your kitchen and you have not seal it regularly, water may seep into the sink, causing a leakage-like problem. Natural stone sinks share the feature of porous. Therefore, they need to be sealed to prevent seepage.
