Use gravity to draw rain-barrel water through a low spigot, outlet hose, or siphon. Elevation, hose diameter, air leaks, and outlet level affect flow.

Solar water pumps work well when pump curve, panel output, storage, sun, lift, and daily demand are sized together. Compare direct-solar and battery-backed designs.

Hand pumps suit small water volumes, backup use, and sites without electricity. Compare lift, flow, effort, priming, materials, mounting, and repair parts.

Outdoor water pumps need weather protection without blocked cooling. Shield rain, sun, freezing, and debris while preserving ventilation, drainage, and access.

Manual hand pumps move water without electricity when matched to lift and flow needs. Compare suction and deep-well designs, effort, priming, and maintenance.

Battery water pumps serve transfer, irrigation, sprayers, and emergencies. Match voltage, chemistry, runtime, flow, head, water type, and charging plan.

Suction hand pumps lift water about 20–25 feet, while deep-well designs place the mechanism below. Actual depth depends on design, elevation, and condition.

DeWalt has offered cordless transfer pumps, but models change. Verify the current catalog and compare battery platform, head, flow, fittings, and water limits.

Many pumps need a check or foot valve to hold prime and prevent reverse flow, but placement depends on design. Follow the manual and avoid excess restriction.

Bleed pump air by shutting power off, opening the vent or priming port, filling as specified, sealing it, and restarting. Persistent air may mean a suction leak.
