Hoping someone here can be kind enough to give me some advice/info on a query for a friend of mine.
He's planning to replace his old single panel radiator to a new double panel one. At the moment the two pipes going into the radiator comes up from the centre and goes outwards to the radiator valves with lots of exposed pipework. He would like to get rid of the majority of the exposed pipes and as plastic polypipe is flexible, he wants to know whether he can join plastic polypipe to just above where the copper pipes comes up from the solid floor and directly into the radiator valves. He realises that using the plastic pipe will break the continuity of existing metal pipes which is used for earth bonding. How would he go about reinstating the continuity?
Any advice/info would be greatly appreciated.
Generally speaking all pipework is bonded at the boiler plumbing rig however, the new rad should have an earth tag fitted, usually at the bottom header, where a 2.5mm earth wire can be connectd. To be totally compliant all services should be cross bonded as per htg engineers recommendation.
