Hi hope you can help. Light is on that says low system pressure. Have opend the valve and needle now round to 3 but still not working. I have tried using the reset button and low pressure light goes out but as soon as I let button go it comes on again. The reset light is not on. Got no heat or hot water at moment.
Thanks all
Bolly.

Should be only 1 bar max. At 3 bar the safety valve will have let go. Any dripping from the discharge pipe externally?

Thanks for quick reply. I think there has been something out of the discharge pipe and have heard the odd shoosh?
Regarding the pressure, I was advised to put the needle between 1 and 2.
How do I get it back down?
Thanks for help

Water pressure switch needs cleaning/replacing
