How do I drop the pressure in my halstead boiler I opened the valve too muc?
The pressure on my cobi boiler dropped so I opened the valve it was hardly moving so I kept it open until it crept up to 1.5 Bar. I got up this morning and it was up to nearly 4 !!! How do I drop it down again?
You will have to drain some water from one of your radiators via the top bleed screw. It's easy, just get the litte square key and drain into a container until the pressure drops back to 1.5 bar.

out side there will be a drain valve open it till the pressure goes back down to 1.5 get some one to look at the gauge and let you know when its at 1.5 then close the drain tap
