My friend asked me where she could window-shop for commercial pumps. She and her hubby are in the process of revamping the water line of their commercial building. The local water supply company upgraded its mains.There is no longer a need for commercial buildings to dig their own water wells for the water company will now be able to service all. However the need for a commercial grade water pump is needed to pump water up the 5th floor water storage tank. I wonder how much a 2HP water pump costs.
