Has anyone actually compared the cost of the larger water tap and line versus the cost of a tank and booster pump setup? Don't forget that the pump may require backup power if the primary power doesn't meet the definition of "reliable" per NFPA 20. Then there's maintenance, inspections, etc. that will go on for as long as the owner occupies the building. In the future the pump and tank setup may actually turn people away from the building if the owner ever decided to sell it while a municipal service to a fire sprinkler system may be a benefit.
Until someone has actual sat down and priced the options you don't have a valid comparison. Craig L.

My problem is that the incoming service is a 1¼", and to bring in a larger service is very expensive because of utilities and other obstruction that's in the way, the GC suggested that we put in a tank and booster pump, to me it sounds crazy to install a tank and pump for a building that's less than 4000 sq. ft. when you have available city pressure. Any ideas how to go about this, please advise.
