Delta Kitchen Faucet Leaking From Handle – How to Fix it

A leaking kitchen faucet can be a nuisance, especially if it’s coming from the handle. Not only is it annoying, but it can also lead to an increase in your water bill. In this article, we’ll guide you step-by-step on how to fix a Delta kitchen faucet leaking from the handle.

Identify the Problem

The first step in fixing your faucet is to identify the problem. The most common cause of a leaking Delta kitchen faucet is a worn-out cartridge. The cartridge is a small valve that controls the water flow. Over time, it can become worn and damaged, causing leaks.

Other possible causes of a leaking handle could be a loose mounting nut or a damaged O-ring. These are also easy to fix and will be covered in this article.

Turn off the Water Supply

Before starting any repair work, it’s essential to turn off the water supply to your faucet. This can be done by turning off the shut-off valve under the sink. If you can’t find the valve, turn off the main water supply to your house.

Remove the Handle

Once the water supply is turned off, remove the handle. Depending on your faucet model, you may need a Phillips head screwdriver or an Allen wrench to remove the handle.

If you’re not sure how to remove the handle, refer to the manufacturer’s instructions or consult a plumber.

Remove the Cartridge

With the handle removed, you should be able to see the cartridge. Use pliers to remove the retaining clip that holds the cartridge in place.

Once the clip is removed, use pliers to pull the cartridge out of the faucet. If the cartridge is stuck, use a cartridge puller tool to remove it.

Inspect the Cartridge

Inspect the cartridge for any signs of damage or wear. If the cartridge is damaged, you’ll need to replace it with a new one. If it’s just worn, you can try to clean it with vinegar and a toothbrush.

Replace the Cartridge

If the cartridge is damaged, remove it and replace it with a new one. Make sure to insert the new cartridge in the same orientation as the old one.

Reinstall the retaining clip to hold the cartridge in place.

Check for Leaks

Once the cartridge is replaced, turn on the water supply and check for leaks. If there are no leaks, reinstall the handle.

Tighten the Mounting Nut

If the handle is still leaking, the problem could be a loose mounting nut. Use pliers to tighten the mounting nut under the sink.

Replace the O-ring

If the mounting nut is tight and the handle is still leaking, the problem could be a damaged O-ring. Remove the mounting nut and replace the O-ring.

Reassemble the Faucet

Once you’ve fixed the problem, reassemble the faucet. Make sure to tighten all the screws and mounting nuts.

Test the Faucet

Turn on the water supply and test the faucet for leaks. If there are no leaks, you’re done!

Conclusion

Fixing a Delta kitchen faucet leaking from the handle is a simple and easy task. By following the steps outlined in this article, you can save yourself the cost of hiring a plumber and fix the problem yourself.
