2 weeks ago our water would not work without the heating being on. We had British Gas come take a look and the chap spent a couple of hours replacing some parts and all was well. Whilst here he recommended a Magnabooster 2 filter and we bought one on-line and a friend who is an ex-plumber fitted this last week, He drained the system and put cleanser through first then came back 2 days later and put inhibitor through and then fitted the filter and then put the leak sealer through that we had bought. We then filled up the system again and left the pressure at the top of the green triangle. That was Thursday. Last night I noticed that even when the system was on (and had been on all day) the needle was half way in the green triangle and I was worried that once the heating went off and the system cooled down then the needle would drop and possibly turned off the system completely so I repressurised the system up to the 1.5 mark which I then expected to fall to the top of the green triangle when the system cooled down. This morning I noticed that the needle was up in the red section - completely over-pressurised so I let water out of a radiator. I have continued to do this all day and even took the front off the boiler and turned the red knob that releases the pressure. I have watched the needle go down to the top of the green triangle and left it but after less than an hour the pressure has raised again - the system is not even switched on and I have checked that I have not left the filling loop open. What have I done wrong??!! I really don't want to call my plumber friend and he was here so long last week and I don't want to call British Gas as they have been out twice as well. Have I broken something??
