Replacing a kitchen sink valve is a pretty straightforward process and can be done easily. Many times in older homes you will need to update these valves when you move in, or if you are having trouble with a leak or drip. Here are a few materials and tools that you will need during the replacement process as well as some steps to help guide you along the way.

Step 1 - Turn Off Water

Turning the water off in your home is an important step that you absolutely cannot forget to do. If you skip this step you may end up flooding the kitchen and causing damage to your home. Completely shut the water supply off to your home and then place a bucket under the current valves. Once the bucket is underneath the valves, you can open them up and allow for them to be drained of the sitting water. this may take a few minutes to finish.

Step 2 - Remove Old Valves

Be sure to wear gloves and goggles as you continue with this project. You will need to disconnect the water supply line with either a saw or a screwdriver. if it is not soldered, a screw driver should be able to do the trick. Use a wrench to remove the valve completely as well as the nuts and screws that are holding it in place. You will often need to loosen and remove a compression fitting, depending on how it was installed. Discard any of the old hardware.

Step 3 - Replace with New Valves

Once everything is off, you can begin with the replacement valves. You will need to slide on the nut to the ends of the threads that are visible. After this, the compression ring will slide right on. Next you will need to wrap the ends of the pipe with a piece of Teflon tape carefully and then attach to the valve. Now, use a wrench to connect and tighten the end of the valve with the compression ring end. You will want to make sure that you are taking extra care when tightening these valves and compression rings as they will be holding together the entire pipe system.

Step 4 - Finishing Up

Many times you can caulk around the base to avoid any leaks. While this is up to the installer, it cannot hurt. Use a caulking gun to go around the base and then a damp sponge to wipe off any of the excess. Let it sit and dry for 48 hours before you consider turning the water back on and testing it out. If you see any gaps in the caulk, you can add more after the 48 hours and allow it to dry again.

Now that you have replaced the kitchen sink valve, you can turn the water supply back on to the house. Test to make sure that the valve is working correctly and that you are not having any dripping or leaks.
