Biasi Boiler loosing pressure

[miajanjua]

Biasi Compact HE 28Kw boiler loosing pressure.

I thought it might be a slow leak, so i added a leak sealer to the system about 4 weeks ago.

I still have a slow leak.

The running pressure is kept around 1 bar at full running temp of 70C.

Could it be the over pressure safety valve? if so how do I check for that?

Can it be any thing else?

Please help.

Is there no one on the forum who is willing to help me out?

If your unsure if water is coming from pressure relief valve then put a baloon over pipe and you can then see if any water enters baloon
