subpump cost
1 An average sump pump (pedestal or submersible) for a typical home runs about $100-$300 depending on the horsepower, materials (plastic is less expensive than cast iron or stainless steel), flow rate and the height the water needs to be lifted to discharge it. An average installation of a sump basin and pump (not including drains) runs about $250-$600 for parts and labor, depending on the quality of the equipment, ease of access and local rates. 2  One homeowner had a plumber install a middle-of-the-line sump pump and basin for $305.
