Normally mucky system. Recommend system is flushed.
Vent air from system and then screw black plastic cap in. It wont leak then
Kinda eliminates the auto bit though?
Same as me after a curryTakes a while to get all the air/gasses out of a sealed system
The new grant combi has 2 aavs and the ordinary boiler has a radiator type manual one on the return.I've seen recently that new Grant boilers now don't have AAV's! they have brass air "pips" like on radiators.
What I was wondering is; would it be worth keeping a few in my van so I can fit these instead of changing the AAV's for another one that is just going to leak again??
don't shoot the messenger!! but seriously the boiler cover cant be taken off by non GSR engineers but should not be left open, Honeywell say leave shut and MI say leave open, how conflicting!!
I cap prv
Corse he's jokingdo you mean something else? if you cap the "pressure relief valve" the system will not relieve pressure when there is a problem and potentially explode, so hopefully you don't "cap the PRV"
