I looked at some old threads and I'm not sure if I'm on the right track. I get a "bang" in the water heater, one only, as it nears its heating cycle, when I turn a valve off (like the sink or shower), or sometimes while it's just sitting there doing what water heaters do. It's an envirotech water heater and only 4 years old. Super hard water that leaves stains on glass and vehicles I can't remove. I've flushed several times. Installed a H20 pressure regulator, I have an arrestor on the hot line below tank and cold line by the outlet to sprinkler system. Anyone had anything similar? Is it the tank and buildup? Any ideas? I'm thinking of replacing tank next, but eliminating by removing appliances is expensive!
