Question to all about the above. Have unvented qualification but little experience of installing or maintaining them.
Went to one of these with a dripping safety pipe. Water coming from the T&P valve not other 8 bar PRV.
Water pressure in area v.high (above or close to the 3.5 bar pressure the pressure reducing valve is set to).
The pressure reducing valve is letting by so that will be changed over the next few days when available. Customer also wants new T&P valve too.
Expansion vessel pressure is 2 bar. A regular contributor to this site who DOES have experience of these systems has told me that the 2 bar pressure SHOULD be OK. However the data badge on BOTH cylinder & vessel state that the pressure should be 3.5 bar. Given that there are pressure related problems and I don't want to look like a tit, I think I will charge it to the 3.5 bar stated on the badge.
Could anyone help with: what's the best way of charging these to 3.5 bar, (petrol station?) and does anyone agree with me that given the high water pressure applied to the installation (3.5bar-ish) that the vessel should be fully charged to 3.5 bar?
Cheers
