Installing an air admittance valve under your kitchen sink can help prevent unpleasant odors from entering your home and maintain proper ventilation in your plumbing system. An air admittance valve, also known as a cheater vent or a one-way vent, is a small device that allows air to enter the plumbing system while preventing sewer gases from escaping into your home.
Before you start the installation process, make sure you have all the necessary tools and materials. You will need an air admittance valve, PVC pipe cutter, PVC primer, PVC glue, and a wrench. Additionally, it’s essential to check your local plumbing codes to ensure that installing this type of valve is allowed in your area.
Start by turning off the water supply to your kitchen sink. Then, locate the existing plumbing vent pipe under the sink. Remove the pipe by using a wrench to unscrew the nuts connecting it to the sink drain and wall. Carefully disconnect the vent pipe and set it aside.
Next, measure the length of the vent pipe you just removed. Cut a new piece of PVC pipe to the same length using a PVC pipe cutter. Apply PVC primer to the ends of the new pipe and the existing drain pipe. Then, apply PVC glue to both primed areas and push the new piece of pipe onto the drain pipe. Hold the two pipes together for a few seconds to ensure a secure bond.
