Everything you need to know about the Drench system — how it works, what it needs, and how it protects your home.
A standard Drench system can spray 2,500 gallons on your house and property for 4–4.5 hours, powered by three 280Ah LiFePO4 batteries.
An extra-large Drench system can spray 5,000 gallons over 4.5 hours using six 280Ah LiFePO4 batteries.
This depends on the size of your home and the complexity of your Drench sprinkler plan. Your plan will recommend a minimum tank size, but you can also opt for a larger capacity. We'll make sure you have a sufficiently sized battery to get through your water supply.
Our standard setup is designed to work with a 2,500 gallon tank. Our extra-large setup works with a 5,000 gallon tank. We can also customize the system for even larger water storage if desired.
Not for grid-independent operation. Your Drench system relies on solar panels, battery backup, and water tank storage to operate without continuous grid power or a municipal water supply. You will need to fill and top off your water tank, which can be done with a garden hose.
If you do have access to utility power and water, Drench can also run on those — and will switch seamlessly to backup sources if either is interrupted during a fire event.
The number of sprinkler heads depends on the size and shape of your home. Each sprinkler head covers a radius of up to 30 feet, meaning your entire structure plus a 30-foot buffer zone on all sides will be soaked with water and firefighting foam.
Drench designers typically provide a 10-foot overlap between sprinkler heads for improved protection wherever possible.
Drench will automatically activate your sprinkler system when a fire is detected within 7 miles of your home — no action required.
If you need to manually activate the system, you can tap "Start My System" in the phone app or press the physical Activate button on the Drench unit itself.
Class A foam lowers the surface tension of water, helping it penetrate and saturate burning materials at depth. It extinguishes embers, aids fire suppression, prevents re-ignition, and reflects radiant heat — making it significantly more effective than water alone. It's widely used by professional fire services for fighting structure fires.
Class A foam is completely safe. It contains no hazardous materials, is non-toxic, and is readily biodegradable. It has been in use since the mid-1980s for wildfire fighting with no reported health or environmental issues.
