A supply line leak may not sound like a big deal – especially if you don’t use the sink often – but ignoring this problem will only lead to more trouble in the future.

Note: if you’re not actively checking, a supply leak in a kitchen cabinet or vanity can go unnoticed for quite some time. Unfortunately, by the time you notice, there may be additional damage.

Here are a few signs that you’re dealing with a supply line leak:

• Dampness, puddling water, or water stains in the cabinet
• Signs of moisture on the supply line or surrounding pipes

If you have reason to believe you have a supply line leak, grab a flashlight, turn the water on, and get into position. As the water runs, pay close attention to where the leak is coming from.

From there, you’ll want to mark the leak and take action. For example, if the valve stem is the culprit, you may be able to fix the problem by tightening the packing nut. If that doesn’t work, it may be the valve.

If you’re concerned about making things worse, as opposed to fixing the problem, you’ll want to contact a licensed plumber. Don’t hesitate to reach out to us the moment you find water in your kitchen cabinet or vanity. We’re available to provide immediate assistance.
