Cut off the pipe leading from the well point as close to the well point as possible.
Clean the pipe end. Glue a 1 1/4-inch PVC pipe thread fitting to the cut-off pipe.
Thread a 1 1/4-inch check valve onto this fitting. The exact location in the pipe between the well point and the pump to install the check valve doesn't matter. But the closer to the well point the check valve is located, the easier it will be to prime the pump.
Install the jet pump in a location as close to the well point as possible. The closer to the pump, the less work the pump will have to do to suck the water up from the ground. Jet pumps are available with 1/2-, 3/4- and one-horsepower motors. Don't expect much more than 5 or 6 gallons per minute from any of the pumps. Go with a medium or large pump if the water table is more than 15 feet below ground level or if you are using the well to provide water for a home.
Thread a 1 1/4-inch male pipe thread to a 1 1/4-inch PVC pipe adapter into the port of the jet pump labeled "inlet."
Use lengths of 1 1/4-inch pipe and the appropriate elbows or other fittings to route the pipe from the check valve to the inlet fitting you installed on the pump.
Connect the pump's port marked "outlet" to the water-system's pressure tank.
Things You Will Need
- Jet pump
- 1 1/4-inch PVC pipe
- 1 1/4-inch PVC pipe fittings
- PVC pipe cleaning solvent
- PVC pipe cement
- 1 1/4-inch check valve
- A jet pump can extract water if the water table is within 25 feet of the surface.
- The well point and the pipe to which it's attached can be inserted using water pressure -- called jetting -- or simply driven into the earth using a post driver.
