Now that you are at this stage ,is there any water dripping from the boiler ? If not you can probably put central heating on. Pressure gauge on boiler should be 1 bar only..........edit ,as long as you have NOT turned off the isolators on the flow and return , as I advised you to earlier. If you have turned them off don't run the boiler.
No water dripping from the boiler at present. I think the leak has to be on the inlet feed somewhere. Obviously I'm very limited in my knowledge of this sort of thing. I didn't turn any other screws other than the one for the DHW.
Pressure is about 2 BAR. You guys know what you are doing but not sure how comfortable dad will be putting the heating on - better to just wait for a pro to come and fix - that's what he will say.
