Deciding to repair or replace gas and electrical appliances damaged by dirty floodwaters can be a difficult decision. Deciding to salvage or replace damaged equipment will be influenced by the length of time in the water, the level of the flooding and the amount of coverage allowed by the insurance and flood-relief programs.
Some things you need to consider are:
- Warranty -- Repairing the equipment or appliance may void the warranty.
- Reliability -- Dirty floodwater can cause parts to corrode, causing break downs.
- Age of the equipment/appliance -- New equipment/appliances offer better energy efficiency, thus saving money on monthly energy costs.
- Insurance coverage -- Allowances offered by the insurance adjuster.
- Safety -- Corrosion or clogged parts not replaced can cause fire, explosion or electrical shock.
- Cost -- Extensive repairs for parts and labor may cost more than buying new.
Any work done on electric or gas appliances and equipment should be done by a qualified, licensed contractor, not by a do-it-yourselfer, no matter how skilled.
- Have a professional check for signs that the oil tank moved. Even buried ones can float when flooded.
- Have a professional check metal or brick chimney for cracks, dirt, debris and leaks. These problems can cause fires or carbon monoxide poisoning when the furnace is turned on.
- Manufacturers usually recommend that all motors, electrical components, safety controls and (for gas equipment) gas valves be replaced.
- Controls on water heaters, furnaces, boilers, room heaters and conditioners will become clogged when flooded in contaminated water.
- Defective gas or oil control devices can cause a fire, flashback or explosion.
- Defective controls on electrical equipment can cause a powerful shock, causing injury or death.
- Flooded water heaters (gas and electric) should be replaced.
- Any HVAC duct insulation that was in contact with floodwaters should be replaced.
- Ductwork with wet insulation should be taken apart, cleaned, dried and disinfected.
- Any HVAC ductwork in the crawl space of a flooded home should be replaced.
- Split system heat pumps should be replaced if one or both of units moved with the flood.
- Call an appliance technician to check your appliances.
- Manufacturers usually recommend that all motors, electrical components, safety controls, and (for gas appliances) gas valves be replaced.
- Refrigerators and freezers with wet insulation cannot be salvaged.
- If there were only a few inches of water in the house, refrigerators and freezers are probably fine.
- Ovens and ranges are usually salvageable. Wet controls should be replaced.
- Have an appliance technician check and replace the pilot orifice and any valves on gas ranges that were in contact with floodwaters.
- Have an appliance technician or electrician check all electrical contacts and connections on the washer and dryer and replace if wet.
Call the customer service of the manufacturer who is on your major appliance (many 800 numbers below). They can give you advice or possibly financial help before you attempt to plug in the appliance.
Make the decision on replacing or repairing based on what feels right to you. Your safety and your life may depend on it.
The Gas Appliance Manufacturers Association recommends that all flood-damaged plumbing, heating, cooling and electrical appliances and related systems should be replaced rather than repaired. It also strongly recommends that all work on flooded equipment be done by a qualified, licensed contractor.
