Automatic Ventilation Seal During Flooding
The Flood Protection Model from Well Domes is designed to actively defend your well against rising water and contamination. At the core of this model is a ventilation channel with a built-in baffle and check valve. When floodwater enters the vent, the baffle floats upward, sealing off the vent. Once the water recedes, it automatically drops back down, reopening airflow.
- No maintenance required
- Check valve closure is fully passive
- Optional manual shut-off cap adds another layer of control

Regulatory Relevance
According to the U.S. Environmental Protection Agency, floodwater can cause serious structural damage to well casings and expose private water sources to dangerous contamination. From displaced debris to invisible pathogens, floods pose a major risk to unprotected wells.
“Flood Conditions at the Well - Swiftly moving flood water can carry large debris that could loosen well hardware, dislodge well construction materials or distort casing.”
