    Bonding combi boiler gas pipes

    From my understanding you need to run both a 10mm earth from CU to water stop clock and seperate 10mm to gas, exception being if cable is uncut can link both gas and water together. In a scenario where been asked to change consumer unit but getting to gas pipes of combi boiler is practically...

    Electrical Cables on hot plumbing pipes

    Recently had an extension done. Noticed electrician had run mains electrical cables right on to the hot feed from the boiler which gets very hot. Is this a safety issue? Can the insulation stand the heat for hours on end?..

    Power cables and hot water pipes.

    Hello :) Just been doing some investigations into running power from the CU in the house out to my shed. I lifted the floorboards on the upstairs landing and found that power cables have been laid right next to the central heating water pipes. This can’t be safe, surely?
