Pilot was extinguished. Relit pilot and showed homeowner how to relight pilot. Encouraged homeowner to invest in water alarm to prevent potential damage caused by tank leaking. Will email estimate. I noticed 1’ of piping at breech is dryer vent. We will provide estimate to repipe. Pilot went out again as I was completing form. Considering the age of the water heater, the dryer vent and the pilot going out, I encouraged homeowners to replace water heater. Will email estimates for the various things presented during call, Water heater is operating well at the time of this service.
