@DoctorEldritch Shoot, I wouldn't even know how to invent something like a water pump. I am the wrong kind of engineer. 😂

You can ask @WolfyKnight if you ever need one. He is the right kind of engineer. 😉

Though, the Da Vinci pump, I think, was not to help with fires, but to lift large quantities of water at high altitudes with less effort. It was like an ancient plumbing system.
