Are you dealing with the maddening drip, drip, drip of leaking bathroom sink? There are several reasons why this issue might crop up. But whatever the cause may be, the end result can be water damage and even mold. It’s vital to get under the sink and get to the bottom of the issue as soon as possible. Let’s take a look at why your bathroom sink might be leaking and how you can fix the issue.
There is a range of reasons why a bathroom sink might start leaking. Before you can fix the issue, it’s important to identify where the leak is coming from. Start by emptying the sink and drying everything off. Once the area is moisture-free, you can run water through the sink to see if you can find where the leak is sprouting from.
Check the water supply, p-trap, and sink drain connection – these are the most common problem areas. Remember, leaks in any of these areas can be very small so if you don’t see the source immediately, lay paper towels around the sink drain or water supply lines to get a better idea of where it’s coming from. Check back in a few hours to see where the water is coming out.
Another way to check for leaks if it’s not immediately obvious is to wrap toilet paper around the supply line, connections, and supply valve. It will likely reveal where the water is coming from after a few hours.
If you still can’t seem to figure out where the water is coming from, the P-trap might be to blame. Check if this is the issue by filling the sink, opening the drain stopper, and looking for leaks in the trap as the water drains.
A corroded tailpiece or a loose drain connection could also be the culprit of a leaking sink but these issues are not as common.
The first step in fixing a leaking sink is the turn off the water supply. You can do this by twisting the valve located at the water supply line. If this isn’t available for any reason, you can turn off the water supply for your entire home. Be sure to allow the last of the water to empty out before starting on any repairs.
