Hi guys,
Our ensuite has the usual shower, toilet and sink.
On occasions the toilet or sink would empty the trap in the shower.
There isn't an air admittance value near these 3.
Could one be installed under the sink. It is a very small ensuite. What is that thing on the right? Doesn't look like a valve but looks odd to me.
Edit: is it an anti siphon valve?
To confirm rightly or wrongly the system doesn't vent outside. The main bathroom has an aav and so does the downstairs loo. No problems with these.
Thanks
