Rated 5 out of 5 by from Soil stack vent. This is a very welcome product. It reduced the need for extra pipe and fittings and allowed me to use access equipment for a much lower height. Saved a few hours and d less time on the ladder. Worth every penny!

I have bought the external use air admittance valve a few days ago. Fitted ok but now the toilet is very slow running. The bowl al;most fills to the top and takes 30 secs or more to empty. Any ideas?

We have a septic tank which seems to be working well.
Asked by: Beatman

Does the top unscrew?

Asked by: BillyDing

Will this fit in a 110mm connector

I'm going to install the McAlpine DC1-BL drain connector. I want to install this air admittance valve directly into that connector without a piece of pipe. Will this be possible or will I need to use a bit of 110mm pipe in between?

Will this solve intermittent sewar gas smell in house?

Ongoing intermittent sewar gas smell in house despite plumbers not finding any leaks! Smell can go for days then return for a few hours then go again! Will this help?
Asked by: Fee2201
There could be a number of reasons causing the sewer smells. An air admittance valve will only help if there is pressure within the system that is sucking the water from waste traps. You will also need to ensure that the drainage run is connected to main drains and not to a sewer treatment system as you will need to leave a open soil pipe for venting if it is connected to a treatment system.

Can this item be used on a cesspit vent pipe

Asked by: Tiny1
No, we do not recommend the use of an air admittance valve on a cesspit vent pipe as it doesn't allow any air out of the system and could lead to a build up of smells and gasses.
