I had called and asked about one of our Sta-Rite heaters that gives off a loud pop sound upon start-up. It's actually quite loud. We are somewhat self sufficient with equipment maintenance in general here. I am familiar with how to service these to some extent, but wanted to get some guidance before I tear into this unit.
