What is the question? I have a durgo valve to my soil stack. it doesn't smell.

I'm not sure of the question to be honest, I was hoping for a discussion with PigletJohn!

Our new house has a Durgo valve in the upstairs bathroom. We have intermittent problems with smell there and the plumber we used to install the downstairs bathroom says it's probably to do with the Durgo valve.

He was not keen to look further into it and I've spoken to a couple of other plumbers who are also not interested. At this point I'm hoping PigletJohn can offer some pointers.

A durgo is a cap that is put on the top of a soil pipe when it terminates inside the house (traditionally, soil pipes terminate outside the house, above window level, and are open at the top so odours can escape).

A Durgo has a nominally one-way valve which is supposed to prevent odours escaping.

If When they jam, odours escape, usually into the bathroom.

The Durgo is usually walled up inside a duct or box, often tiled over to make it difficult to get at.

They are often used when a bathroom is re-fitted, or an extra one added, because it is less work for the plumbers than running an external vent, and it isn't their house, so they will be long gone before it starts to smell.

Thanks @PigletJohn, I have sent you a message, I hope that's ok!
