Can help me. I brought a repo property and all the utilities were off so when i moved in i got a "gas safe" plummer to re-fill, service, vent etc the central heating system. When he was doing this he removed the valve in the boiler & water went everywhere, he cleaned it & replaced it. But the boiler would not register any pressure and therefore wont work. He went away saying he was going to source a pressure valve & something eles, this was on sat morning & the weather has got colder & colder so as he is now not answering the phone i need to get the boiler fixed before my pipes freeze & burst?!?!?
