Can this be used with a macerator?
I have bought a Wasteflo macerator and it says, "to prevent water siphoning from the outlet pipe, an air admittance valve must be used capable of withstanding 6 psi". Is Floplast valve suitable for this purpose?
None of the Air Admittance Valves in the FloPlast range are suitable for use with a macerator.

Is there any mounting orientation requirements for the AAV, i.e. can it be mounted at the end of a horizontal pipe or must it be mounted vertically?
All FloPlast air admittance valves should be installed vertically.

Below Overflow or Above?
I am a little confused by these. I have seen a number of comments saying they can be fitted below the overflow level, but also seen other comments saying they should be fitted above the overflow level of the sink. Which is it? I intend to fit one in a bathroom cabinet, so it makes a big difference.
FloPlast air valves have an A1 rating which means that they can be installed below the flood level of connecting appliances. All you need to make sure is that they are installed at least 200mm above the highest wet entry point into the soil stack.
