Hi all, here's hoping you can help. A few days ago I posted a message about our heatline vizo boiler not igniting and some of you very kindly helped me out with some advice as the pressure on the boiler had dropped too low, I opened the valve and the pressure crept back up, closed it again and the boiler started to ignite again and was fine. I have closed the valve as tightly as it will go, but now the pressue has gone the other way and is at the max on the boiler and the radiator in my daughters room is pouring out with water which is leaking through the ceiling! Have I done something wrong? And do you have any ideas what I should do know? Hoping for some advice before having to call a plumber as they are few and far between in our area and cost the earth, but we are very short on money at the moment. Please no sarcastic comments. Many thanks in advance for taking the time to read this.
