How to Buy a Submersible Sump Pump
- 1). Select between automatic and manual models. Automatic pumps turn on when the water reaches a certain level. Manual models require that you turn the pump on during bad weather or after flooding has already occurred.
- 2). Compare head pressure, which indicates how many vertical feet the pump can pump water before losing water pressure, and select pumps with ratings of 30 to 50 feet. For smaller homes, select pumps with head pressure ratings of 10 to 20 feet.
- 3). Compare features like cord length and check valve. Cord length allows you more flexibility in pump placement. Pumps with check valves help prevent water from seeping back into the pump.
- 4). Choose between cheaper poly-composite (plastic) models and heavy-duty stainless-steel models. Although poly-composite submersible pumps provide a solid, waterproof housing, high-quality steel composite housings often offer larger motors that provide stronger head pressure. Because they consist of hardened steel, they also resist pressure from shifting rock.
- 5). Compare prices. Submersible sump pumps cost $69 to $200. Compare retailers that often offer similar brands with price differences of 10 percent to 15 percent.
