Putting off repairing leaks can lead to mold in your walls, damage to your vanity and flooring issues down the road. This post will discuss common plumbing problems that can cause a leak underneath your sink. The first thing to determine is where the leak is coming from. Remove everything from underneath the sink and dry the area out.

A leak under the sink could be poor caulk around the faucet or sink itself, a damaged p-trap, cracked PVC pipe, leak in the wall and a host of other issues. The problem can be narrowed down pretty easily by drying off the area and using a flashlight on different locations. The most common problems are the p-trap or a bad pipe connection.

Arguably the most common reason you’ll find water beneath your sink is that your drain has a leak in it. Shifting plumbing lines, worn-out connections, or even pipe corrosion could cause fractures in the plumbing lines beneath your sink, which cause water that flows down your drain to slowly and steadily leak out.

A bathroom sink can leak due to a loose pipe connection, bad drain pipe, and a leaky sink drain flange.

In fact, the leak that’s being caused by a faulty O-ring or worn-out cartridge is almost definitely the same leak that’s happening under your sink. It’s probable that the water is simply making its way from the base of your faucet to the underside of your sink.

Sometimes, there is a third connection, as well, if your sink has a separately connected sprayer. Any of these connections can break, corrode or rust, and cause water to drip. These leaks usually go under the radar until they soak everything in the storage under the sink. This is because the connections are rarely in a visible place.
