I need to change the automatic air vent completely and wondered how I should go about this as I have just added inhibitor to the system so don't want to dump it all.
Someone I was speaking to recently said that if I drain the system down to that highest point I should be alright without having to drain the whole system down. To do this I presume I would need 2 people, one to look at the AAV and one to stop the drain off point?
Can anyone out there shed any light on this for me?
