First, ditch those flow restrictors in your faucets.
Next, a hose is useful if the fire is small or outside. If the fire is big, yoy need to get out because the smoke will f*** you immediately. A couple breaths of burning synthetic items will put you down.
Last if you have a well pump and hook up at the feed line before the pressure tank, the lint should be large to the tank, then reduced down to feed the house. My house line is 1-1/4" and my well pump can send 80ish gpm which would only be restricted by the 3/4" contractor hose I have.
I also have a fire pond above my house. I just need a fire truck to turn into a prepper rig.....
