We have a combi boiler in the garage that does the central heating and the
hot water, usually the pressure is about 1.2 to 2.0 on the dial, its up at
just over 3.0 at the moment, does anyone know how to reduce the pressure in
the system ?
We have like a flexible filler loop pipe on it that we use to increase the
pressure if needed by turning a tap for a few seconds but have no way of
any help appreciated
You need to find out why the pressure is so high.
suggests the expasion vessel may be faulty.
If you have just overfilled then bleed some water out of a radiator.
I had the same problem last week. It turns out there was dirt caught in the
filling valve. When the filling loop was removed there was a constant drip
which was fixed by flushing the loop through into a bucket.
