Quick answer: If your well pump keeps tripping the breaker, it is drawing more current than the circuit allows. Usually that is a short in the wiring or splices, a failing motor, a pump jammed with sand, a bad start capacitor or control box, low voltage, or a pump that starts so often it overheats….
Quick answer: If only the hot water smells like rotten eggs, the water heater is almost always the source. Harmless sulfate-reducing bacteria react with the tank’s magnesium anode rod and make hydrogen sulfide gas. It is a nuisance, not usually a health risk.

Quick answer: Navien E012 is the error code that means “flame loss.” The burner lit, then the flame went out or the heater stopped sensing it, so the control shut off the gas. Navien’s user manual lists two owner-level checks: clean the intake air filter and make sure the electrical cord is properly grounded. Confirm…
Quick answer: Navien E110 is the error code that means “abnormal air pressure.” The heater has detected that air is not moving through the exhaust and intake path the way it expects, so it shuts down. Navien’s user manual gives two owner-level checks: make sure the exhaust pipe is free of obstructions, and clean the…
