Initial Pilot Flame & System Diagnostics

Before requesting emergency plumbing service in the West Valley, run through these essential visual inspection checks to identify why your pilot burner flame keeps extinguishing.

1. Inspect Flame Color

2. Dust & Thermocouple

3. Gas Safety Protocol

Peep through the glass view port. A healthy flame burns steady and bright blue. Yellow or orange flickering points to dirty orifices or improper gas supply.

Fine desert dust builds up rapidly on sensor probes in garage water heater closets, triggering safety shut-offs even when gas pressure remains normal.

If you notice a rotten egg odor around your heater, shut off the gas control knob immediately, exit the area, and contact our licensed technicians.
