How to Install Air Admittance Valve for Toilet
Installing an air admittance valve (AAV) for your toilet can be a straightforward and cost-effective solution to improve the efficiency of your plumbing system. An AAV is a device that allows air to enter the toilet pan when the water level drops, preventing the need for a siphon to flush the toilet. This not only conserves water but also reduces the risk of clogs. In this article, we will guide you through the process of installing an air admittance valve for your toilet.
Step 1: Gather the Necessary Tools and Materials
Before you begin the installation, gather the following tools and materials:
– Air admittance valve
– Teflon tape
– Adjustable wrench
– Screwdriver
– Pliers
– Pencil and ruler
Step 2: Turn Off the Water Supply
To prevent any leaks or water damage, turn off the water supply to the toilet. This is usually done by turning the valve located behind the toilet tank.
Step 3: Remove the Toilet Tank Lid
Carefully remove the toilet tank lid to access the bolts that secure the tank to the bowl. Use a screwdriver to loosen the bolts and lift the tank off the bowl.
Step 4: Locate the Outflow Pipe
Once the tank is removed, locate the outflow pipe, which is the pipe that connects the toilet bowl to the drain. The air admittance valve will be installed on this pipe.
Step 5: Measure and Mark the Installation Point
Use a pencil and ruler to measure and mark the location where the air admittance valve will be installed. Ensure that the valve is positioned at least 6 inches above the floor and 1 inch away from the wall.
Step 6: Cut the Outflow Pipe
Using a hacksaw or pipe cutter, carefully cut the outflow pipe at the marked location. Make sure the cut is clean and straight.
Step 7: Install the Air Admittance Valve
Slide the air admittance valve into the cut section of the outflow pipe. Apply a generous amount of Teflon tape to the threads of the valve and the pipe to create a watertight seal.
Step 8: Reattach the Toilet Tank
Place the toilet tank back onto the bowl and tighten the bolts to secure it in place. Ensure that the tank is level and that the bolts are not over-tightened.
Step 9: Reconnect the Water Supply
Turn the water supply valve back on and let the tank fill with water. Check for any leaks at the valve and the connections between the tank and bowl.
Step 10: Test the Air Admittance Valve
Perform a flush test to ensure that the air admittance valve is functioning correctly. The toilet should flush without any issues, and the valve should allow air to enter the toilet pan when the water level drops.
By following these steps, you can successfully install an air admittance valve for your toilet. This simple upgrade can save water, reduce the risk of clogs, and improve the overall efficiency of your plumbing system.
