Armstrong air purgers are a pain & expensive if needle & seat leak on air release mechanism.
There is an add on to rectify very easily & I am not sure if its only being done in Australia & who actually invented modification, but it works.
-Add on is basically plug off air release connection with 1/4" plug.
-Remove relief valve on top if instaled (1/2")
-Screw in Parker stainless steel LLC float switch
-In outlet of LLC float screw in a tee , with one branch of tee re-instal relief valve & other branch of tee screw in a solonoid (small as possible) followed by needle valve & check valve.
-Bracket if necassary
-Wire up solonoid in series with float switch .
Takes several hours & finished. The only thing really to maintain is solonoid valve which you could instal a stop valve before it as well if you wanted to .
Everything is screwed type fitting
