Why is my kitchen sink drain pipe leaking at the connection?

One of the most common and noticeable leaks in your home is a kitchen sink drain pipe leaking at the connection. Here are some of the most common culprits of kitchen sink drain pipe leaks:

1. Wonky Pipes:

   Plenty of plumbing repairs have been thrown together with whatever was on hand, or with incorrectly sized pipe, or even a mixture of pipe sizes and improper lengths. This can cause a build-up of pressure at the joint causing it to fail. In this instance you’ll want to call us for a quote, unless you’re comfortable performing the repair yourself.

2. Clogged Trap:

   Clogs can lead to a build-up of pressure, as well. This can cause pipes to crack or split at the joints, and begin to leak. Beware of liquid drain cleaners, as they can cause further erosion of problematic joints and weakened pipes. If your problems persist, you should call a professional to help you fix the issue appropriately.

3. Loose Compression Nut:

   Likely the most common reason why your drain pipe is leaking at the connection. A loose compression nut will not seal the pipe correctly, so be sure to check the condition of the compression nut prior to scheduling a plumber to come out.

4. Damaged or Worn Compression Nut:

   If tightening the compression nut doesn’t solve your problem, you’ll want to inspect the to see if the nut may be cracked or simply worn out. A crack or worn area on the nut will allow water to pass through, so the nut will need to be replaced. Over tightening the nut, too, can cause it to crack, so be sure that you’re only tightening it enough to create a good seal.

Kitchen sink leaks are never a welcome guest in your home, but they are fairly visible and easy to catch shortly after they begin. Pooling water, stains or dampness in the cabinet beneath the sink are all typical signs of a leak. It is very important to address a leak immediately to avoid further, more serious damage occurs.
