House was built with some ridiculous fire sprinkler system. The system is designed to always have fresh water in the lines- I guess fire gives a shit if you give it stale water.

I am on a well with a 1hp pump, hydrant at the well casing. Line runs into the basement feeding a 82 gallon pressure tank. From the pressure tank, the line feeds a 400 gallon storage tank plumbed to a 5hp booster pump. From there, a main line basically runs the perimeter of the basement, with Ts off to the sprinklers, faucets, and toilets.

It seems to me that using 6 total hp to feed water to the house is a bit silly, as well as expensive when the electricity is factored in. If i flush the toilet, the booster pump runs for 2-3 minutes. The pressure tank is pretty much pointless, as it is only pressurizing the hydrant and the line to the float valve. (No hydrant and a switched float would have made more sense.

Any way I can get away with re plumbing all this crap? I dont mind flushing the sprinklers from time to gime, but this seems to be done a bit stupid.seems that i could T off of the line coming from the pressure tank, feed my faucets/toilets, and not impact the sprinklers. Maybe leave an outside faucet connected to that apparatus so i can flush it.
