Hi I'm not panicking. I rang freeholder and told her that the plumber bodged the pipes in my loft and the lease officer agreed to let me get another heating engineer to come and redo all the pipes and properly re-lag them. I told her about the cable, we didnt get much chance to talk as she was busy but I'm sure she will allow me to get spark to check cables etc. Anyway, my question is this. The plumber who bodged came recommended by two people who are local and were pleased with his work. Another plumber who just moved out of my area, who has an excellent reputation but cannot do the job now hes moved out of the area also was suprised to hear the plumber i used made a bodge job. I've spoken to some nice heating engineers who were patient with me and answered my quesitons even worcester bosh, the manufacturer of my boiler was patient. He said the 10mm pipes are too narrow as my water pressure is high Opinions on flux are mixed among plumbers, WB said it needs wiping off as it will corrode but Im not worrying about that. What I do want to ask is this. I plan to ask a trustmarked gas safe firm, (dunno who yet) to take out all of the copper pipes and re-lag them, I just want to know, do heating engineers generally lag pipes or do they just fit copper pipes? I'm asking because im having trouble getting a decent pipe lagger. Another booked up reputable firm said that 15mm lagging on 10mm pipes with poorly taped joints and exposed copper will stand a good chance of causing a freeze and burst. He said that he has heard of quite a few burst pipes this winter cos of poorly lagged pipes but as i said he wasnt trying to get me to hire him as he is too far away. I don't quite know who to hire, and as I won't be able to see the pipes, I don't know how i can be sure if the new firm properly lags the pipes and don't want to spend every winter dreading bursts. So, is it normal practice for heating engineers who fit copper pipes to lag them? and, if I choose a decent trustmark firm, will they lag them properly? Hope someone can help.
