Troubleshooting a hand pump that won’t draw water?

Checking Suction and Water Level

When a hand pump won’t draw water, the first step is to ensure there’s sufficient suction. Check the water level in the well or tank to confirm it’s at or above the pump’s recommended operating level. Typically, this is between 20-30 feet below the pump. If the water level is too low, you may need to install a submersible pump or a deeper well.

Priming and Free Movement

Next, check that the pump is primed and the handle is moving freely. Priming involves filling the pump’s suction pipe with water to create a vacuum. You can prime the pump by attaching a hose to the suction port and submerging it in the water. Then, slowly lift the hose out of the water while opening the discharge valve. If the pump still won’t draw water, check that the handle is moving freely and not stuck. Remove any debris or dirt that may be obstructing the pump’s movement.

Advanced Troubleshooting

If the pump is primed and the handle is moving freely, it’s time for more advanced troubleshooting. Check the pump’s seals and gaskets for any signs of wear or damage. Replace any damaged seals or gaskets with new ones. Also, inspect the pump’s valves and pistons for any blockages or corrosion. If you’re still having trouble, consider consulting the pump’s manual or contacting the manufacturer for further assistance.
