Rated 4 out of 5 by from FloPlas air admittance valve Easy to fit and allowed me to get rid of the soil pipe in the bathroom so the whole room looks better after the refit. Not a hint of a smell so I hope its working.

Rated 5 out of 5 by from Air Admittance valve? How do you review an air admittance valve. It just sits there and does nothing for 99.999% of its time. No smells to report so I suppose that means it's ok. I can say it was easy to fit and looks the part.

How can it be fitted below highest overflow level?

I am intrigued, as I would love to fit one inside the sink cabinet, 200mm above highest wet entry to 4" soil pipe. What feature has been added to allow this AAV to be below spill-over level?
Asked by: PhilipCC
FloPlast air admittance valves have an A1 rating which means that they can be installed below the flood level of connecting appliances. All you need to ensure is that the air admittance valve is at least 200mm above the highest wet entry point going into the soil stack that it is being fitted onto.

can this be fitted at an angle?

We have recently discovered that the builders of our 4 year old flat have not fitted this valve to the top of the soil pipe within the loft space. The pipe is roughly at a 45 degree angle. Will the valve still work? Thanks
Asked by: chrisj55
No, the air admittance valve must be installed up right and is unlikely to work in any other position.

If this can be fitted below the flood level of connected appliances what is minimum height that vent pipe needs to be from the floor?

Asked by: Terrysevenoakes
The air admittance valve needs to be installed a minimum of 200mm above the highest wet entry point connecting into the soil stack.

Can this be used on a property that uses an underground septic tank?

Asked by: Iwan
The AF110 can only be used on a property with a septic tank if there is another open vent pipe for the septic tank.

1960's Stack Pipe

I am looking at using the Floplast AAV internally in a 1960's soil pipe. Can I fit the AAV directly into the soil pipe or will I need an adapter?
Asked by: Gorilaz
Yes, the AF110 should fit directly onto the existing 1960's soil pipe.
