I am having problems draining my pressurised heating system. I am the home owner, and not a plumber. The property is a new build, three storey house, 16 rads, s plan, 3 zones. The issue is that the rads on the middle floor (8 rads) are not draining. The top floor and some of the ground floor rads have drained correctly, 3 and 5 rads respectively.
Heating turned off. All TRVs and lockshields have been fully opened. There are three drain-offs - all opened. All 2 port valves latched to open (3 zone pl HW). There are a couple of bleed valves in the airing cupboard - opened. Pressure is reading zero. I thought this was all I needed to do, but perhaps there's something else.
Any advice appreciated.
Cheers
