Sump Pumps

Choose a submersible pump if you want a unit that sits inside the sump basin and handles higher water levels with quieter operation; choose a pedestal pump if you need easier access for maintenance and a motor kept above the basin, typically for lighter-duty pumping

Select based on flow rate (gallons per minute or hour) and head (vertical lift). For most basements, a 1/3 to 1/2 HP pump with a 30–50 feet head rating and a flow of 2,500–4,000 GPH at low head is adequate; larger basins or long discharge runs may require higher capacity

Float switches control automatic operation; common types include tethered floats, vertical floats, and electronic level sensors. Vertical or electronic sensors tend to be more reliable in tight basins or with debris, while tethered floats are simple and work in larger, unobstructed basins

Look for features such as a solids-handling impeller, corrosion-resistant materials (stainless steel or thermoplastics), and a removable strainer or screen. Regular inspection, clearing debris from the basin, and using a check valve on the discharge line also reduce wear and clogging

Match the pump discharge outlet size (commonly 1-1/4" to 2") to avoid restricting flow; use smooth, rigid piping for longer runs. Install a full-port check valve near the pump to prevent backflow and short cycling, and position it so it is accessible for maintenance

Ensure the pump is connected to a properly grounded circuit with an appropriate circuit breaker and GFCI protection if required by local code; avoid using extension cords, and consider a dedicated circuit to prevent overloads during heavy use

Inspect and test the pump every 3–6 months: check the power connection, exercise the float switch, clear debris from the basin and inlet, inspect the discharge line and check valve, and replace worn seals or cords as needed
