FAQs

  • How long can Drench operate on battery backup?
    1. 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.
    2. 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?
    1. 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.
    2. 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?
    1. No, 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.
    2. Yes, if you would like your Drench system to operate indefinitely while grid power and water are available. 
  • Will I lose connectivity to my Drench System during a wild fire?
    1. 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?
    1. 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.
    2. Drench designers will typically provide a 10’ overlap between sprinkler heads for improved protection whenever possible.
  • How do I activate my system?
    1. Drench will automatically activate your sprinkler system when a fire is within 7 miles of your house.
    2. 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?
    1. 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.
    2. 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.
