Rated 5 out of 5 by Easy to replace Durgo Valve The old valve, which the plumber installed, failed after 10 years. I purchased this Durgo valve from Screwfix and it was so easy to fix. It took more time to actually get to the old valve than it did to actually change it. Great product & great price. 21 May 2015

Answer: 
The seals on the air admittance valve will only open if there is a build up on negative pressure within the system. If there is not enough negative pressure then the air admittance valve will not open.

Answer: 
The air admittance valve can be used however being installed horizontally it would never work and we could not guarantee that it would seal so may let smells out. It would also be an expensive way of blanking off the pipe as you could use an access cap or similar.
