Soil Plumbing Can Be Installed Internally by Installing an Air Admittance Valve!

Although most soil pipes are by default installed on the exterior of the house or building wall, they’re also made to accommodate an internal setup. The pipes themselves are not aesthetically displeasing for many home owners, but some may prefer the absence of these pipes if they’re still in the process of building. When installing soil pipe systems internally you will need an air admittance valve instead, which is available here at EasyMerchant at an amazing price!

Please note, it’s not uncommon for air admittance valves to be referred to as ‘Durgo valves’ or ‘AAVs’. These terms can be used interchangeably – so if you’re looking for a Durgo valve – you’re in the right place.

What is an air admittance valve?

Push Fit Soil Air Admittance Valves are most commonly made from plastic (PVC) as this makes them simple to work with, light weight and more economical than their cast-iron system’s options that are heavy, expensive and difficult to manage. A soil pipe (sometimes known as a vent pipe, stack pipe and waste vent pipe) is the pipe that would usually connect to your pan connector that attaches to your toilet and would typically run externally down the side of the home or property and connect to the underground sewer system. For attaching waste pipe to dispose of waste water from the bath, sink, and appliances. Occasionally the soil system will operate internally, and in this case a Push Fit Soil Air Admittance Valve will be required to permit air flow to the system when venting air (and thus smell) from being discharged to the property.

The soil vent pipe and soil pipe fittings are set up to transport sewage and waste from top floor toilets, baths and sinks and appliances to the underground drainage system. The vents or Push Fit Soil Air Admittance Valves allow smells and odours from the waste and drainage system to be released to the atmosphere. Placing the outlet port means the odours are transported away and released where they won’t be noticed. By allowing air flow and oxygen to the system that the vents also help the process of aerobic sewage digestion.

How does an air admittance valve operate in a domestic or commercial soil stack system?

An air admittance valve uses a clever system that’s activated by negative pressure. When the pressure balance is recreated, the valve closes again. This allows air to be drawn in when required, but prevents unwanted odours from entering the home.

Air admittance valves frequently feature rubber seals, to help make a complete seal even if there’s slight air pressure – so raising the effectiveness of the valve and preventing any odours from escaping through small gaps.

Typically, air admittance valves have been fitted with a push-fit joint, which enables pipes and sockets to be fitted together without using tools – again the ring seal system creates a connection that will stand up to raised water and air pressure. But they can also be purchased with solvent weld joints, which utilizes a chemical reaction through the application of a solvent to create a watertight and airtight permanent bond.

Where should you fit air admittance valves in your 110mm soil stack system?

Aiir admittance valves are generally put on a soil pipe that is a minimum of 200mm above the maximum water entry point – ie; the maximum stage wastewater will reach within a soil pipe. They are most commonly installed in the end of a soil pipe, but can also be installed inline, using a branch.

Typically, air admittance valves have been placed within lofts or cupboards, to prevent them from becoming an eyesore. However, they do require a level of ventilation, so it’s important to ensure they are in a place that sees a natural circulation of air – to allow air to pass over the valve.

Air admittance valves may be set up externally, but this isn’t really common and usually only done if the soil pipe is too close to an opening window. Open pipe outlets must be installed over 3 metres from a window which opens, but air admittance valves can be nearer than this. If you’re installing air admittance valves, you ought to obtain a valve that is frost-resistant and unaffected by extreme weather conditions.
