Sime super 80 low pressure problem?
Hi,
I'm no boiler expert and can't seem to increase the pressure in my bolier. The grey dial is on just above 0 but the red dial is on 1. I've tried increasing the pressure and the grey dial does increase but quickly falls again, even when I turn the valve off. Can anyone help?
the boiler is a sime super 80.
Thanks in advance
