By fitting the valve, in this scenario it will prevent any foul smelling gases from escaping into the inside of your home as the valve seals the top of the pipe when closed and only opens to draw air in. Next, use a tape measure to measure up 200mm and then mark the wall and then measure from the base of the collar of the T-piece up to the top mark and this is how long your vertical pipe needs to be.

Once you have found the ideal install location the next task is to cut the existing waste pipe so that you can fit a T-piece or equal-T as it’s known to run the vertical pipe to fit your AAV. As you can see, the advantages of using them are many but, as with all things, there are also some disadvantages. Color Variants: For aesthetic or coding purposes, these valves come in different colours to match or identify different plumbing systems. Airflow Requirements: Different valves allow for varying amounts of airflow. It’s essential to choose one that can handle the airflow requirements of your plumbing system to maintain efficiency. Solvent Weld: The base of the unit features a collar that slips over the top of a 110mm pipe and is then glued in position using solvent weld adhesive. This will ensure a firm fitting but if the unit fails the only option for removal is to cut the top of the pipe offIn pretty much all cases it’s best to use solvent weld fittings as once they are fitted and the adhesive has dried they are pretty much guaranteed not to leak. There are two scenarios to installing an AAV, the first being installing it into existing waste pipework and the second as part of a brand new installation of a sink, bath or the similar. In the majority of cases it will be into existing pipework after a pressure issue has been identified.

Cut a piece of pipe to length, clean any burrs off, apply some solvent weld and then push it into the T-piece and ensure it’s vertically upright. The most commonly sold AAV is the rubber push fit ones that we sell here at EasyMerchant. They’re easy to install, a matter of just pushing them into the pipe, and they’ll create a watertight and airtight fitting. Some will prefer the solvent weld air admittance valves though, as once cemented these will create a permanent connection. Are there any issues to consider when using an air admittance valve?How high should you install the air admittance valve? The short answer is a minimum of 200mm above any water entry point. So if you imagine your soil pipe run, then durgo valve / AAV must be fitted above the highest connection to the soil pipe from any sink, bath or toilet that is connected to it. Usually you’ll find the installed at the very end of the soil pipe. If you need to, you can install them in line using a soil pipe junction.

Adjust the spare top inlet using a spirit level so that it is pointing directly upwards so when the vertical pipe is fitted it is upright and square. The first job to do is to select a length of existing waste pipe where the valve can be installed. Choose an area with enough space to work in comfortably and also one that will allow you enough height to install the valve so that it is above the highest water inlet. In some very rare cases there may be absolutely no choice but to install an AAV externally and in these cases you can only use a specific model built to be used outside. This air admittance valve is manufactured from modified uPVC, and comes in white. It has been designed to work with solvent weld jointing, which ensures the joint is secure, durable and leak-free. Otherwise it may be that the AAV has been installed in an incorrect location, such as below the point of another water entry to the system. For example, the durgo valve has been installed below a toilet on the floor above this will result in valve not being able to draw the air in as it is supposed to and causing negative pressure within the system. Air admittance valve under sink?As good and useful as air admittance valves can be they can also cause some problems, especially when they become old and worn.
