Yes. Sizing comes from two numbers: how fast water enters the pit, and how far the pump has to lift it. Neither is guesswork — and picking the largest pump on the shelf is as wrong as picking one too small.
What We Measure
- Inflow rate. How quickly the pit fills under real conditions. In New Mexico that means sizing for a monsoon downpour, not an average day — the peak is exactly when the pump gets tested.
- Total dynamic head. Vertical lift from the pit to the discharge point, plus friction losses through the piping. A pump rated for a certain flow at zero lift delivers considerably less at ten feet of head.
- Pit dimensions. A pit that is too small causes rapid cycling, which wears out motors fast.
- Discharge routing and where the water can actually go.
- Available electrical and whether a dedicated GFCI circuit exists.
Why Oversizing Is a Real Problem
Homeowners assume a bigger pump is safer. An oversized pump empties the pit almost instantly, shuts off, and restarts as soon as it refills — short cycling that wears bearings and switches far faster than steady operation. It also does not actually protect you better, since the limiting factor is usually the discharge line, not the pump.
Submersible vs. Pedestal
Submersible sits in the pit, runs quieter, handles more debris, and generally lasts longer. The usual recommendation.
Pedestal has the motor above the pit, costs less, and is easier to service, but is noisier and less tolerant of a pit that occasionally floods above design level.
Battery Backup Is Not Optional Here
The strongest recommendation we make. The storm producing the water is frequently the same storm cutting your power, and a primary pump without electricity is no protection at all. A backup pump with its own battery covers exactly the scenario that floods basements.
What Else Belongs in the Install
A working check valve, a pit lid, discharge routed well away from the foundation, freeze protection on the outlet, and a water alarm.
