After 2–3 inches of water flooded their basement, a homeowner said the gas water heater’s pilot was out. They saw only a little standing water while checking the gas valve, then turned the heater on low; the pilot relit, and they planned to monitor it.
The homeowner said the water remained in the basement for a few hours and money was tight after replacing the sump pump. Reddit replies focused on whether water reached the gas control valve and whether the heater’s base was dry. One commenter said it should be fine if water stayed below the valve and the base was dry; another was less certain but said relighting might work.
