Can a Durgo valve be fitted externally?
Can a Durgo Valve be Fitted Outdoors? Yes, but this is usually only done when the pipe is too close to an opening window. The Building Regulations state that a vent pipe outlet must be at least 3 metres from an opening window, but with a Durgo Valve fitted, you can place the pipe within this limit.

Where do you install an air admittance valve?

Can a toilet be capped with a Durgo valve?
While this assumption is true, they can sometimes be capped, provided certain Building Regulation rules are met and a Durgo Valve is fitted. When a toilet is flushed, air is pushed down the drain pipe and additional air needs to be sucked in to replace it.
How are air admittance valves and Durgo valves installed?
This opens the Diaphragm A and valve B allowing fresh air to be sucked in through the side vents C and down into the system. The equalisation of pressure prevents the foul air from escaping and the water seals in the traps (bath, toilet and basin) from escaping.

Can a Durgo be mounted inside a house?
Anyone got any ideas, I can’t put durgo inside. Building regulations assume that an AAV will be indoors in an inhabited space. I don’t think the actual wording of the regs disallows an AAV to be mounted outside hence the grey area. If your BCO says no it will be difficult to argue against that.
