Air admittance (Durgo) valve: A1 designated.

Any recommendations please (ease of fitting, longevity, functionality etc) for an ‘A1’ designated Air admittance (Durgo) valve needed for a forthcoming conservatory roof replacement/upgrade?... i.e. a valve that will be fitted below the flood level of connected appliances in this configuration:-

(as ever, all advice gratefully received.Thanks)

Not forums rpm; only one,...I got a one word reply which said simply ‘Mcalpine’ ,...hence the reason I cast my net on here;...(apologies if that’s against the rules) 😕.

Screwfix sell a FloPlast A1 Durgo valve which is much cheaper than the Mcalpine. I’ve use FloPlast (and Mcalpine) products in the past but I have no experience whatsoever of A1 Durgo valves.

I realize it’s a bit of a niche question and I was hoping for a more specific reply based on functionality, reliability and personal experience,... but I guess I’ll buy the Mcalpine based on little more than it’s the most expensive so it’s probably(???) the best,...WTF 😀, sod the expense!

Thanks for taking the time to reply, Simon & rpm.
