DRIVEN WELL

Drive the point several feet below the water table.

NOTE: A packer type foot valve can be installed in the well (Figure 3, Illustration B). This type of foot valve allows the well to be filled with water when priming and makes the inlet pipe much easier to test for leaks. Follow

As an alternative, an in-line check valve can be used with a driven well (Figure 3, Illustration C). The pipe between the check valve and the water level will always be under a vacuum.

NOTE: When a lake is used as a water supply, make sure the inlet pipe is deep enough to be submerged at all times. Protect the pipe from damage from swimmers and boats.

DEEP WELL INSTALLATION

DRILLED WELL (4 IN. OR LARGER) WITH TWO PIPE JET (FIGURES 17 AND 4)

1.Assemble a 1-1/4 in. foot valve (not included) to the jet body. A 1-1/4 in. coupling is required to connect the larger pipe to the jet assembly.

2.Connect the 1 in. pipe threads into the smaller opening in the jet body.

6.Install the horizontal pipe from the well to the pump. Piping from the vertical well pipe to the pump should never be smaller than the well pipes.

7.Slope both pipes upward toward the pump to prevent trapping air. If the horizontal distance exceeds 25 feet, see Chart 2 (on page 5) for the recommended pipe sizes.

1.Install a 1-1/4 in. foot valve (not included) to the jet body. A 1-1/4 in. coupling is required to connect the larger pipe to the jet assembly.

2.Connect the 1 in. pipe threads into the smaller opening in the jet body.

3.Lower the jet into the water below the lowest anticipated water level, but never closer than 18 in. from the bottom. Sand or debris may be drawn into the system if the jet is too close to the bottom.

4.Provide protection for the jet and pipes against damage from boats or swimmers if a lake is used for the water supply.

NOTE: Single pipe packer jets rely on the space between single pipe and inside of well casing for return water to operate jet. Two inch installations must use 1-1/4 in. galvanized steel pipe with special turned couplings (1-13/16 in. O.D.) to avoid restricting flow of return water back to jet.

1.Assemble the foot valve and packer to the jet body.

2.Lubricate the rubber cups with petroleum jelly.

3.Attach the first section of pipe and lower jet into well.

4.Add pipe until the jet is positioned 5 - 15 feet below the lowest anticipated water level. The jet should never be closer than 5 feet from the bottom of the well or sand and sediment may be drawn into the system.

5.With the jet in position, fill the pipes with water to make sure the rubber cups are sealed against inside of the well casing. It may be necessary to move the jet up and down to seat the cups.

6.Install the casing adapter and the horizontal pipes.
