Installation 3

GENERAL SAFETY

Do not touch an operating motor. Modern

motors are designed to operate at high temperatures. To

avoid burns when servicing pump, allow it to cool for

20 minutes after shut-down before handling.

Do not allow pump or any system component to freeze.

To do so will void warranty.

Pump water only with this pump.

Periodically inspect pump and system components.

Wear safety glasses at all times when working on pumps.

Keep work area clean, uncluttered and properly lighted;

store properly all unused tools and equipment.

Keep visitors at a safe distance from the work areas.

Pump body may explode if used as a

booster pump unless relief valve capable of passing full

pump flow at 75 psi is installed.

SHALLOW WELL JET PUMP

INSTALLATIONS:

• Have a vertical depth between the pump and the

water being pumped of 25’ or less.

• Have one pipe from the well to the pump case.

• Can be installed in a bored or drilled well, or in a

driven well.

REPLACING AN OLD PUMP

Hazardous voltage. Disconnect power to

pump before working on a pump or a motor.

1. Drain and remove the old pump. Check the old pipe

for scale, lime, rust, etc., and replace it if necessary.

2. Install the pump in the system. Make sure that all

pipe joints in the suction pipe are air-tight as well as

water tight.

If the suction pipe can suck air, the

pump will not be able to pull water from the well.

3. Adjust the pump mounting height so that the plumb-

ing connections do not put a strain on the pump

body. Support the pipe so that the pump body does

not take the weight of piping or fittings.

You have just completed the well plumbing for your

new shallow well jet pump. Please go to Pages 5 and 6

for discharge pipe and tank connections.

WELL POINT (DRIVEN POINT)

INSTALLATION (FIGURE 1)

1. Drive the well, using drive couplings and a drive cap.

Drive fittings are threaded all the way through and

allow the pipe ends to butt against each other so that

the driving force of the maul is carried by the pipe

and not by the threads. The ordinary fittings found in

hardware stores are not threaded all the way through

the fitting and can collapse under impact. Drive fit-

tings are also smoother than standard plumbing fit-

tings, making ground penetration easier.

2. Mount the pump as close to the well as possible

3. Use the fewest possible fittings (especially elbows)

when connecting the pipe from the well point to the

pump suction port. The suction pipe should be at

least as large as the suction port on the pump

(include a check valve as close to the well as possi-

ble - see Figure 1). Support the pipe so that there are

no dips or sags in the pipe, so it doesn’t strain the

pump body, and so that it slopes slightly upward

from the well to the pump (high spots can cause air

pockets which can air lock the pump). Seal the suc-

tion pipe joints with teflon tape. Joints must be air-

and water-tight.

If the suction pipe can suck air, the

pump cannot pull water from the well.

If one well

point does not supply enough water, consider con-

necting two or three well points to one suction pipe.

You have just completed the suction piping for your

new shallow well jet pump. Please go to Pages 5 and 6

for discharge pipe and tank connections.

WARNING

Hazardous pressure!

Install pressure relief

valve in discharge pipe.

Release all pressure on

system before working on

any component.
