You will be pleasantly surprised more often than not that they are great tools for keeping clogs and disgusting odors out of your pipes. When it comes to an air admittance valve, there really are not that many problems that you will run into.
#Sewer air admittance valve for toilet free
If there are no clogs and everything seems to be free and clear, then return it immediately. Also, make sure that the air admittance valve is not itself clogged, as that can sometimes be an issue. An air admittance valve leaving behind clogs and sewer odor is faulty, so be sure to find your receipt if you still have it and take the valve back as soon as you see that it is not working. If your problem is not holes in the valve, it’s time to look at the valve itself.
Just be sure your pests are under control before you do. As for fixing the holes, you are going to be better off getting a new valve. If you feel like you can handle the pest control problem yourself then give it a try, but you still may want to keep an exterminator’s number handy just in case. Get an exterminator if you need as rodents can be a recurring cause for issues like this. Your best bet when it comes to holes in your valve is to go to the root of the problem. Remember that these valves should last anywhere from 20 to 30 years, so if they are only lasting for a couple of years, there may be some problems that need addressing.
Sometimes you may find that even with an air admittance valve, there are still clogs and a sewer odor. If you happen to notice that your air admittance valve is acting like it is not sucking up what it should, then you may have a hole or two on your hands. Holes can sometimes still be chewed through if rats or mice are a persistent problem. Although air admittance valves are tested for their durability against rodents, sometimes they cannot persevere.
