Air Admittance Valves, also called AAVs, are important for your home’s plumbing. They stop sewer gases from coming into your house. This guide helps you choose the right one.
Key Features to Look For
When you buy an AAV, you need to know what to look for. Here are some important things:
- Size: AAVs come in different sizes. You need to pick the correct one for your pipe. Check your local building codes. This tells you the right size. Sizes are usually measured in inches.
- Flow Rate: This tells you how much air the valve can let in. You need a valve that can handle the amount of water you use.
