Looked on my builder, for someone to come out and look at my boiler. Had Farooq come out twice. He was really good, and tried lots of different things, to resolve the issue, and explained what he thought it might be, and everything else he tried, he'd tell me what he was hoping would work, but nothing would, so I will need a new boiler, it is about 16yrs old. I really appreciated all the effort Farooq, had made and would recommend him to anyone in the future.
