average cost of sump pump
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. A submersible sump pump costs more and only lasts 5-15 years, but is typically quieter and less obtrusive than a pedestal model. 2  Both types of sump pumps range in horsepower from a quarter to 1HP; a 1/3HP sump pump is standard for most homes.
