My boiler is over pressurised. If I shut off the water supply it settles at about 2.5 bar, with the water it goes up to 3.0-3.5 bar. Any ideas how I can drain it?
get a bucket and open a radiator vent, pressure will drop around half a bar per average bucket, failing that twist prv to release pressure through blow off to outside wall
