Guide · Water HeaterStanding-pilot gas tanks use a thermocouple or thermopile heated by the pilot to hold the gas valve open; FVIR models add a thermal switch and flame arrestor.

Pilot assembly, thermocouple/thermopile, burner and gas valve work go to a licensed plumber or gas technician.

Totally cold water usually means a tripped high-limit (ECO), a dead upper element or a failed upper thermostat. Always find out why the ECO tripped before calling the job done.
