Hi all, I have a recurring problem with my central heating system, the pipework from my boiler to the hot water tank keeps on bursting, it has occurred 3 times now. The pipe is 28mm Hep2o and it is physically splitting the pipe, not blowing off at the fittings. The house is 9 years old and this is the 3rd time it has happened, always on the same piece of pipework, should there be some pressure relief to prevent the pipe from bursting as when it bursts it pretty much explodes. Does anyone have an idea as to what the issue could be? Is it a defective peice of pipe or is there a fundamental problem with the system?
