Replacing an Existing Pump
4
DEEP WELL
Hazardous voltage. Disconnect power to pump before working
on pump or motor.
Step 1. Drain and remove the old pump. Check pipe for scale, lime, rust,
etc., and replace it if necessary.
Step 2. Install the pressure regulator and pressure gauge in the pump body
(see Figure 1).
NOTICE:
Your old ejector (in the well) may not be properly
matched to your new pump. If the pump does not perform
properly, we recommend that you install ejector kit R-E520-100-01,
included with the pump.
Step 3. Install the pump and tank 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.
Step 4. Adjust the pump mounting height so that the plumbing 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.
Step 5. Run piping from the discharge tee in the tank flange to the household
piping. The discharge piping must be at least as large as the tank tee.
Install a relief valve in the discharge pipe capable of passing the entire
pump flow at 75 psi. Run a pipe from the relief valve to a floor drain
or some other convenient place to carry off the water.
You have just completed the well plumbing for your new deep well jet
pump/tank system. Please go to Page 7 for electrical connections.

Hazardous voltage. Disconnect power to pump before working
on pump or motor.
Step 1. Drain and remove the old pump. Check the old pipe for scale, lime,
rust, etc., and replace it if necessary.
Step 2. Remove the pressure regulator from the pump body. Replace it with
a 1” NPT close nipple, a 1”x1”x3/4” NPT Tee, and a 1” NPT pipe
plug (see Figure 1). Install the pressure gage in the plugged hole in
the pump body (see Figure 1).
Step 3. Install the ejector kit. Follow the instructions provided with the kit.
Be sure to align the venturi with the top hole on the front of the
pump (see Figure 3).
NOTICE:
Always replace the ejector when replacing the pump in a
shallow well installation.

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
