If you are a homeowner or condo owner, coming home to a leak under your kitchen sink is always an unpleasant surprise. Water leaks, even seemingly minor ones, can lead to various issues, including water damage and the spread of mould in your house. It is therefore important to identify the source of the problem as soon as possible. In this blog, we’re going to explore some of the common causes of kitchen sink leaks.
Big Clogs and Blockages
Big clogs are one of the most common causes of kitchen sink leaks. They are normally caused by accumulations of food scraps, grease, soap scum, and other debris. As the blockage worsens in your drain system, it will put an increasingly amount of pressure on your pipes and plumbing connections, which can eventually result in leaks. Clogs in the P-trap pipe under your sink can also prevent the water from draining properly, causing it to overflow.
Corroded or Damaged Parts
Parts of your plumbing system will inevitably corrode over time due to continuous exposure to water and certain cleaning products. Once corrosion occurs, it can weaken the pipes, valves, and other plumbing fittings, thus leading to leaks. For instance, a corroded valve seat will prevent the valve from closing properly, which can cause a continuous drip of water. Additionally, if the washers inside a faucet are damaged, it can compromise the watertight seal, leading to leaks.
Garbage Disposal Issues
Blockages in your garbage disposal can also cause leaks. Likewise, improper or excessive use of the garbage disposal can cause internal damage, which in turn can lead to cracks and leaks.
Loose Water Supply Connections and Damaged O-Rings
Loose water supply connections to the kitchen faucet or water lines can cause water to drip from under the sink. Likewise, if the O-rings found between your plumbing connections get damaged or dislodged, drips may occur.
Faucet and Drain Leaks
Some kitchen sink leaks don’t necessarily originate from the sink pipes. Drain leaks can occur due to fissures or loose connections in the drainpipe. If they are not fixed promptly, these leaks can cause water to drip into your kitchen cabinet, thus making it seem like the leak is coming from under the sink. Likewise, leaks in the faucet or spout can also drip down into the cabinet, causing water to drip under the sink.
Excessive Water Pressure
An abnormal increase in water pressure can cause damage to your plumbing system, including the connections under your kitchen sink, thus increasing the risk of leaks.
