I have a Hayward 250 Natural gas heater. About a month ago it started popping when turned on. The pops get so forcefull that the above ground pipes move with each bang. I am sort of a novice and figured maybe air was in the lines and expanding. I have tried to configure every flow change possible to see if that would help or eliminate the problem. It doesn't matter if it is configured in spa mode or pool mode.
Any help?
