This is a boiler burner on a cooking range which is only 4 years old. It is leaking and has blown two transformers and the clock to date until I was so dissatisfied I told the fitter not to fit a third transformer until he finds out where small but ever present water was coming from.....which transpired to be a leaking burner. Do I just have to accept this or is it a manufacturing fault, it occurred directly on the seam of the welded joint, I don't know if it is steel or cast iron. Help please thankyou.
