High-Head Sump Pump for a Long Uphill Discharge
A long uphill discharge requires more than a pump with a high horsepower number. Choose a sump pump based on its flow at your calculated…
Sizing & comparisons
Practical help choosing, installing and troubleshooting sump pumps before the next storm.
Size & Head
1/3 HP versus 1/2 HP sump pump
A 1/2 HP sump pump is not automatically the better choice. Compare the pump’s flow at your actual discharge height, basin setup, switch,…
Head-height numbers reviewers skip
A sump pump’s maximum gallons-per-hour number is only part of the story. Head height, shutoff head, pipe friction, check valves, and…
How to Size a Sump Pump for Head Height
Sizing a sump pump by horsepower alone can lead to poor performance. Calculate total dynamic head, compare the pump's flow at that height,…
Backup Systems
Battery backup versus water-powered backup
Battery and water-powered sump pump backups solve the same problem in different ways. Choose based on your outage risks, municipal water…
Diaphragm backup versus DC backup pump
A diaphragm backup pump uses municipal water pressure, while a DC backup pump uses stored battery power. The better choice depends on your…
Primary pump plus backup versus a combination unit
A separate primary pump plus backup usually offers more flexibility and serviceability, while a combination unit can simplify installation…
Choosing
Solid-state switch versus mechanical float
Solid-state and mechanical float switches control sump pumps in different ways. This guide compares reliability, debris tolerance,…
Vertical Float Versus Tethered Float
Vertical floats are compact and work well in narrow sump basins, while tethered floats need more room but can provide a longer pump cycle.…
Comparisons
Can a dirty-water utility pump replace a failed sump overnight
A dirty-water utility pump may keep a basement dry during an emergency, but only if it can handle the water, lift height, discharge setup,…
Cast Iron Impeller Versus Plastic Impeller
Cast iron and plastic impellers can both work well in sump pumps. The better choice depends on water quality, debris, corrosion risk, pump…
Cast Iron Versus Thermoplastic Sump Pump
Cast iron sump pumps emphasize weight, durability, and heat dissipation, while thermoplastic pumps are lighter and resist corrosion. The…
Pedestal pump as an alternative in a shallow pit
A pedestal sump pump can fit a shallow or narrow pit because its motor sits above the water. Compare pit dimensions, switch clearance,…
