Been around for a while, heard of them, but never tried one.
Thins like the BC 38mm air test scare me with these fitted, also do they still self close in years to come if residues ends up down the pipe?
The fact you don't need to use an AAV with these interests me though!
Anyone had problems or good experiences with these?
