Hello stumped by why none of the drain valves seem to drain. All rads full and vents show water if opened. Valves are all downstairs at the lower points, but on opening any of the three, nothing ?.
Its been a while since last drained but if i recall there was no problems last time.
Any suggestions as waiting to drain from the air valve is a tad long.
