House flooded and was recently sold in June. Water damage happened, and water is also getting in the basement when it rains, and foundation is wet. Pools of water are seen on the floor. Water heater is not staying lit. I noticed lots of rust and moisture at the burner chamber, and it may be starting to leak. Existing water heater shows it is for natural gas, yet the home is on propane. Water heater MUST be replaced. I shut the gas off to the water heater. House is currently being completely renovated due to previous owner and water damage. Renter is living onsite in a camper. If we replace the water heater we will not warranty it due to any rust, leaking, or damage incurred due to water getting into the basement. Installing a drain pan underneath would help protect it. I found two replacement options for propane water heaters but they are not stocked locally and must be special ordered.
