Hi all,
Falling pressure..... which I guess can only come from a leak, which must be under my ground floor floorboards as all the ceilings are fine.
The system is only 1 year old and had Fernox inhibitor added.
Ive had falling pressure for about 10 months and have just been using the filler...
Putting staircase into victorian terrace but need staricase that will fit very tight turnaround.
Heard someone mention a pidgeon staircase but what is it and/or look like???
