FAQs

How long can Drench operate on battery backup?
- A “grid-independent” standard Drench system can spray 2500 gallons of water on your house and property for 4-4.5 hours. This is powered by three 280Ah LiFePO4 batteries.
- An extra-large system Drench system can spray 5000 gallons over 4.5 hours using six 280Ah LiFePO4 batteries.
What size tank do I need?
- This will depend on the size of your home and complexity of your Drench sprinkler plan. Your Drench sprinkler plan will recommend a minimum tank size but you can also opt for a larger capacity tank. We will make sure you have a sufficiently sized battery to get through your water supply.
- Our standard setup is designed to work with a 2500 gallon tank while our extra-large setup is designed to work with a 5000 gallon tank. We can customize the system for even larger water storage if desired.
Do I have to supply water and power to the Drench System?
- Not for grid-independent operation. In order to operate independently without continuous grid power and a city/municipal water supply your Drench system relies on solar panels, battery backup, and water tank storage. You will need to fill and top off your water tank which can be accomplished with a garden hose.
- If you would like your Drench system to operate indefinitely while grid power and water are available, then they will need to be supplied to the Drench System.
Will I lose connectivity to my Drench System during a wild fire?
- No, you will not lose connectivity. Your Drench system is designed to connect to the Starlink satellite network which will not go down during a wildfire.
How far can Drench reach?
- Each sprinkler head has a radius of up to 30’, which means your entire house plus a 30’ area around your house will be doused with water and fire fighting foam.
- Drench designers will typically provide a 10’ overlap between sprinkler heads for improved protection whenever possible.
How do I activate my system?
- Drench will automatically activate your sprinkler system when a fire is within 7 miles of your house.
- If you encounter a situation where you need to manually activate your system you can use the “Start My System” button in your app or push the physical “Activate” button on your Drench System
Why do you use firefighting foam? Is it safe?
- Class A foams lower the surface tension of the water, which assists in the wetting and saturation of Class A foams with water. It penetrates and extinguishes embers at depth which aids fire suppression and can prevent re-ignition. Its ability to reflect radiant heat and cling to vertical surfaces have led to its acceptance for fighting structure fires.
- Class A foam is completely safe. It contains no hazardous materials, is non-toxic, and readily biodegradable. Class A foams have been in use since the mid-1980s for fighting wildfires and no issues have been found during this entire time.
