Typical DuroJet Convertible Deep Well Jet Pump Installation
DuroJet Convertible Shallow Well Jet Pump with Conventional Storage Tank
1. Install air volume control on tank.
2. Connect the tube from the air volume control to the tee in the suction. Be sure the connections are tight. Leaking can
cause the pump not to prime.
3. Install a valve and an isolator hose between the tank and the hose plumbing to aid in pump removal for servicing and for
reducing the noise transmitted to the house through the piping.
4. Provide a hose bib (faucet) at the lowest point in the system to drain the system for service or storage.
DuroJet Convertible Shallow Well Jet Pump with Precharged Storage Tank
1. Shut off the power to the pump.
2. Open the faucet nearest the tank and allow all water to drain from the tank.
3. Measure the tank precharge at the valve stem using a tire pressure gauge.
4. If necessary, precharge with an air pump to 2 PSI below the cut in pressure of the pump.
5. Slope the horizontal pipes upward toward the pump to prevent trapping air. If the horizontal distance exceeds 25 ft.
DuroJet Convertible Deep Well Jet Pump Installation Instructions
The DuroJet Convertible Deep Well Jet Pumps have two pipes and the injector is down in the well. This pump is designed for
pumping potable water in applications where the water level is up to 80 feet.
Drilled Well
1. Assemble the foot valve to the ejector. The short tube in the ejector assembly needs to be replaced with long tube (#302922).
2. Connect suction pipe and drive line to the ejector as shown in the diagram on the following page.
3. Install the assembly so foot valve is submerged at least 10 feet below pumping level. Mechanical seal could be damaged
by running the pump dry.
CAuTioN! The foot valve should be at least 18” from the bottom of the well or sand or sediment could be drawn
into the system.
4. After the proper depth is reached, install a well seal or pitless adapter to support the pipe and prevent surface water and
other contaminants from entering the well.
5. Horizontal Piping - Connect horizontal piping to the well assembly. Gradually slope pipe up to the pump location,
eliminating all dips and high spots and using as few elbow connections as possible. All pipe connections should be
absolutely air tight for best pump performance.
6. Fasten the pump down securely in its permanent location to minimize pump vibration when operating.
