Moved water heater for ESOG to complete wall will return on Monday to reinstall water heater and rework vent. Before work was commenced noticed water heater was off prior to water heater being worked on water heater is more than likely not working at this time however, unable to determine because water house will shut off upon arrival due to other trades working in house. Return to reinstall heater thoroughly tested and confirmed the leaks. Everything is working fine at this time.
