A water suction pump helps move water from one place to another by creating pressure or vacuum. On this page, you’ll find options for many jobs:

• Shallow well/jet pumps: Surface-mounted units that pull from shallow sources for irrigation or household boosting.
• Submersible utility pumps: Sit in the water to drain pools, hot tubs, or basements.
• Trash/semi-trash pumps: Handle water with debris, like ponds or floodwater.
• Manual siphon and hand pumps: Simple tools for small transfers or off-grid use.
• Transfer/diaphragm/drill-powered pumps: Compact options for barrels, aquariums, or light-duty jobs.

Compare flow rate (GPH), max head/lift, suction lift, hose size, and power source. Always use the pump only with liquids it’s rated for and follow the manufacturer’s instructions.

Most surface-mounted suction pumps (like shallow well/jet styles) can pull water from around 20–25 feet below the pump at sea level. You’ll often see ratings near 23–26 ft. Actual performance can vary based on:

• Elevation and temperature: Higher altitudes and warmer water reduce suction capability.
• Plumbing setup: Hose diameter, length, and fittings impact friction losses.
• Priming and air leaks: Proper priming and airtight suction lines help maintain lift.

For deeper sources, a submersible well pump that pushes water up from below is typically used instead of pulling from the surface. Check each product’s max suction lift and max head to match your site conditions.

The best pump depends on the job and the water conditions:

• Small transfers: Manual siphon or drill-powered transfer pumps for aquariums or buckets.
• Pools, hot tubs, basements: Submersible utility pumps with a GPH rating that suits your volume and hose size.
• Garden irrigation or shallow sources: Shallow well/jet pumps or booster pumps for pressure.
• Debris-laden or muddy water: Trash or semi-trash pumps rated for solids.
• Off-grid/simple setups: Hand-operated pitcher pumps.

Match the pump to your flow (GPH), head/lift, and power needs. Use a GFCI outlet for corded electric pumps and operate gas engines outdoors. Only pump liquids listed in the product’s specs.

Start by estimating your system’s demand, then choose a pump to meet or exceed it:

1. Flow: Add up sprinkler/emitters’ GPM, then convert to GPH (GPM × 60).
2. Pressure: Note required PSI for your devices; convert to feet of head (PSI × 2.31).
3. Elevation + friction: Add height gains and approximate pipe/hose losses.
4. Suction: Keep suction lift within about 20–25 ft for surface pumps.
5. Power and control: Pick electric, battery, or gas as available; consider a pressure tank/switch for steadier pressure.

Choose a pump whose max head and GPH comfortably cover your totals. A suction strainer and correctly sized hoses can help performance.

A few symptoms can point to pump or system issues:

• Low or fluctuating pressure: Could be clogged suction, air leaks, or worn impeller.
• Frequent short-cycling: Check pressure switch settings and the pressure tank bladder.
• Air sputtering at faucets: Possible suction-side air leak or dropping water level.
• Won’t stay primed: Inspect foot/check valve and all suction fittings.
• Unusual noise or heat: May indicate bearing or motor stress.

Turn off power before inspection. Cleaning strainers, tightening fittings, and re-priming can help, but conditions vary. If issues persist, consider service or replacement. You can find pumps, tanks, hoses, and accessories here to restore performance.
