Mira Sport, installed about 3 yrs ago, hard water area.
On cold, runs fine. When heating water, starts gurgling, then the inlet valve shuts, to immediately reopen, fine for about 10 seconds, gurgles, and shuts valve again. It hiccoughs.
Suspect air getting in somewhere, but all joints ok, no leaks.
Any idea why? Inlet filter clean, no appararent blockage in feed. I'm stumped!
Or could this be due to scale build up in the heater can?
