What Priming Methods Work Best for Shallow Well Jet Pumps?

Gravity Feed Systems

Gravity feed systems are a popular method for priming shallow well jet pumps. This method involves connecting a hose from the pump to a water source, such as a nearby water tank or a water storage container, and then allowing gravity to feed water into the pump. The hose should be positioned at a height of 10-15 feet above the pump to ensure proper priming. It’s essential to use a valve to control the water flow and prevent excessive water pressure.

Air-Admitting Valves

Air-admitting valves are another effective method for priming shallow well jet pumps. These valves allow air to enter the pump and well casing, which helps to remove any airlock or vacuum that may be present. To use an air-admitting valve, locate the valve on the well casing and open it to allow air to enter the well. Once air has entered the well, close the valve and check the pump for proper priming. The valve should be opened periodically to maintain air circulation and prevent corrosion.

Foot Valves and Check Valves

Foot valves or check valves are essential components of shallow well jet pump systems. These valves prevent backflow into the well and ensure that water only flows out of the pump. Installing a foot valve or check valve at the end of the pump suction line can help to prime the pump by preventing air from entering the system. It’s crucial to install the valve correctly and ensure that it’s properly secured to the well casing to prevent leaks and other issues.
