Spoke to Thomas on the Saturday morning about the problem and arranged for him to come round on the Sunday at 11:30 am , Thomas text the next morning to say behind on the first job but will be round asap. He arrived 12:45 pm and we discussed the issue and what I thought the issue was , tommy had a good look round the boiler and tightened all the connections round the TF1 filter ( this seemed to be the issue) tommy could quite easily of recommended replacing the TF1 filter (£100) plus fitting but suggested it only needed all connections re tightening, one week on and no issues of water etc , I would definitely use him again and will be doing so for a boiler service .. thanks Tommy
