Prepare people and property first. This hurricane/tropical-storm guidance also helps organize an Arizona storm response, but local emergency directions and actual flooding risk govern.
Before the storm
Secure loose items if it is safe and there is time. Keep the pool full; do not empty it to receive rainfall. Record normal equipment conditions and know the safe electrical shutdown location. Follow the equipment/cover manufacturer and local emergency directions; do not enter danger to save a pump.
After the storm: inspect before restarting
- Keep people out of water with poor visibility, debris, uncertain contamination or possible electrical exposure. Do not touch flooded controls, submerged outlets or wet electrical equipment.
- From a safe location, document flooding depth, damaged equipment, debris and water level. A submerged heater or electrical component needs qualified inspection before reuse.
- Have safe circulation restored and remove accessible debris with appropriate tools. Check filtration condition and current water chemistry before selecting treatment. Do not assume a universal heavy shock dose makes floodwater safe.
Separate recovery from normal maintenance
Floodwater or sewage contamination requires specific public-health guidance and professional assessment. A pool that is merely dirty after wind/rain is a different case. Identify the contamination source and obtain the appropriate plan rather than mixing more products.
Return-to-use record
Document corrections, equipment inspection, sanitation results and restored visibility. Ask CAS for help when contamination, structural damage or electrical safety is uncertain. Do not claim the pool is safe solely because a photo looks clear.
