Nightmare scenario - our CH system (Combi boiler) has been losing pressure and needs topping up every day. we had a CH Engineer in who said that the microbore piping used (approx 17 years old) needs replacing. He said that the older and cheaper type of piping used apparently didn't have a membrane and thus only lasts 12 years and this is the type used in our house. Is this really true - I cannot believe that trade would market a CH pipe that only lasts 12 years! given the size of the job required to replace it, and the huge cost involved in taking up all the flooring? HELP!
