Wells don’t usually go dry (though they can)….so through the course of a fire it should continue to produce. If it were to go dry during an event like that it would be an amazing coincidence. Having it on a power source not connected to the grid will allow it to keep producing. I’ll have 15,000 gallons in the tanks and hope to add another 10,000 at some point not too far down the road. With the we’ll still running it should continue to put water into the tanks…hopefully at a pace at least close to what we were spraying on the house.
I’ve been using a water wagon with a pump similar to what Magwa has set up. They’re great systems, but the gas tank on that motor runs dry relatively quickly. A generator, even a portable one can run 12-24 hours. A bigger gen with 100 gallon fuel cell will go even longer. It would take a hell of a battery system to run the pumps very long.
