Before you begin the installation process, make sure you have all the necessary tools and materials. This includes an air admittance valve, a hacksaw, PVC glue, pipe cutter, Teflon tape, and a wrench. It's also recommended to have a bucket and a towel on hand to catch any excess water during the installation process.Step 1: Gather Your Tools and Materials
Before you start working on your kitchen sink, it's crucial to turn off the water supply. This will prevent any water from leaking out during the installation process. You can find the shut-off valve under your sink or near the main water supply line in your home.Step 2: Turn off the Water Supply
Using a pipe cutter, cut the drain pipe that comes down from your sink. Make sure to leave enough room for the air admittance valve to be attached. It's recommended to use a hacksaw for this step if you don't have a pipe cutter. Measure and mark the pipe before cutting to ensure accuracy.Step 3: Cut the Pipe
Wrap some Teflon tape around the threads of the air admittance valve to ensure a tight and leak-free seal. This will also make it easier to remove the valve in the future if needed.Step 4: Apply Teflon Tape
Using PVC glue, attach the air admittance valve to the cut pipe. Make sure it is tightly secured and in the correct position. Allow the glue to dry completely before moving on to the next step.Step 5: Attach the Valve
Once the glue has dried, turn the water supply back on and run some water in the sink. This will test if the valve is working correctly and if there are any leaks. If everything looks good, you can move on to the final step.Step 6: Test the Valve
To protect the air admittance valve from any debris or damage, cover it with a valve box or a cover plate. This will also keep the valve hidden, giving your sink a cleaner and more streamlined look.Step 7: Cover the Valve
