[QUOTE="says-les, post: 470049, member: 15145"] I've had at least four visits over two years from Gas Board to a Potterton Boiler which has to be re-pressurised at least once per week. Wonder if it can ever be fixed. I was away for four days and the system pressure dropped to zero. Pipes below floor show no sign of leaks. Is it possible to have an air leak without water showing? There are six radiators divided over an upstairs and downstairs terrace house. Engineer replaced the expansion tank within the boiler three visits ago. What can be done? New system? System is eight years old. Says-Les [/QUOTE]
