Generally no, and it should not be started. Manufacturers are explicit that submerged gas valves, control boards and motors are replaced rather than dried and reused, and a gas valve that appears to work after immersion is a genuine hazard. Have any submerged equipment evaluated by a licensed technician before it is energized.

Above the documented historical high-water line for your specific property, with margin. That is a property-specific number rather than a general rule — we look at the flood mapping and, more usefully, the physical evidence in the basement, which usually tells the story clearly. We move the electrical disconnect and controls up with the equipment and run condensate to a pumped discharge.

No. Standard homeowners policies exclude flood entirely, and separate flood insurance is the only route to a paid claim on equipment lost to rising water. This catches a lot of riverfront owners here by surprise, and it is worth confirming with your agent well before you need it. A sudden condensate line failure is a different category and is often covered.

Proximity to the creek and the river keeps the ground-moisture load high through the summer regardless of flood events. Water vapour migrates through the slab and foundation walls and humid outdoor air condenses on cool surfaces below grade. Dehumidification with a hard-piped drain plus rim-joist sealing addresses it; air conditioning upstairs does not.

Sometimes the burner and blower survive, but the honest answer is that submerged controls and a submerged heat exchanger are rarely worth trusting. Control boards, gas valves and safety switches that have been in floodwater can fail unpredictably afterwards, and the failure modes are the ones that matter. We evaluate rather than assume, and where the answer is replacement we document why, because that documentation is what supports the claim that pays for it.

Because the moisture is arriving as air, not as water. Sitting close to the creek and the river keeps summer dew points high, and humid outdoor air entering a basement where the surfaces are cooler condenses against them. That happens every summer regardless of river levels. The remedy is dehumidification sized for the space with a hard-piped drain, plus sealing the obvious air paths, rather than anything to do with the cooling system upstairs.
