Shut the Water Off

If you can, shut the water off to the whole house, but if not, at least turn the water off to the sink itself. There should be a cutoff valve located underneath the sink somewhere.

Stuff the Pipe

If you’re fixing the link above the cabinet in the sink area, stuff a rag or something over the pipe to make sure loose parts don’t go down the drain and clog it further.

Lay Out the Parts

On a rag next to your workstation, lay out a wrench, screws, and any other parts you may need to finish the job.

Protect the Hardware

If you’re having to fix the faucet itself, wrap the teeth of your wrench in duct tape to keep from scratching the metal. Either way, grab some distilled vinegar to help clean the mineral deposits off the inside of the pipe.

Sometimes, the problem is as simple as tightening a nut or replacing a rubber washer on the inside, but if it’s something more, you might need to do a little more elbow grease to solve the issue.

Fixing a Leaky Kitchen Sink

Below are a few steps you can take to help fix a leaky sink.

1. Assess the Situation

Is the leak coming from the faucet area in the sink or in the pipes in the cabinet below? Are there multiple streams of water coming from different places or is it a continual leak in one location?

Usually, your first indication that something is wrong is a giant puddle forming underneath the sink, possibly hidden by all of your cleaning supplies that are typically stored there.

However, if the leak is coming from a pressurized hose, it could also be sprayed as well, in which case you’ll want to turn the water off before assessing further damage.

A leak from the drain line is a little tougher to diagnose since you won’t be able to see where the leak is coming from until you actually use the sink. If you suspect that’s the culprit, open up the cabinet doors below the sink and turn the water on, watching to see a possible drip.

It could also be a leak in the seal around the drain, which means you’ll need to fill the sink up partially and let it sit to watch for drips. Look for damp areas under the sink or any standing water to identify the problem.

2. Fix the Obvious Issues

If the water is spraying everywhere, chances are there’s an issue with the connection between the pressurized hose and another pipe, so give the compression nut holding the two together with a good turn. Hold one half with a wrench, and use a second wrench to twist it. If the water stops, your problem is fixed.

Alternatively, you might find an issue with the connection up next to the drain itself. These are more problematic because you most likely won’t be able to fit a wrench up there to tighten the problem. Use locking or adjustable pliers to reach next to the drain and turn the nut, hopefully sealing off the leak.

3. Fix (or Replace) the Traps

In some cases, the leak may not be simply from a faulty connection, but from a corroded p-trap, which is the bent section in a pipe that keeps the nasty gasses from returning back up the pipe.

Usually, tightening the compression nuts will keep the leak from happening, but you might also have a blockage that is keeping the water from draining properly. In the worst cases that could also lead to corrosion.

In order to prevent this, take the p-trap off and clean out the blockages. An auger should do the job thoroughly enough, but you may also need to replace the trap entirely if it’s corroded. Once that’s finished, put the trap back on, using the wrench to tighten the bolts securely.

4. Fix Other Leaks

If the pipes aren’t leaking it could be because the seal around the faucet is leaking.

These can be hard to detect, as the water may drip down the inside of the sink bowl and drip from another location, so follow the water trail closely to see if it’s coming from somewhere else.

Alternatively, look for a broken seal around the drain, since that could be a problem also. Either way, a good application of a plumber’s putty should be enough to block the hole and seal the leak.

Finally, the faucet itself may be the issue. Sometimes the washers on the inside can become corroded and not produce a very tight seal; replace the washer completely in order to fix it.

Fixing the faucet usually requires disassembly of the entire faucet, which can vary depending on which type of faucet you have. Regardless, the process is pretty straightforward and shouldn’t be that time or cost-intensive.
