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 control valve and pressure gauge in the pump body (see
Figure 1).
Step 3. If your old pump has the suction pipe (the larger port – see Figure 2)
below the drive port, you will need to install flexible pipe between
the well head and the pump so that the connection will be correct.
(See Figure 3).
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 Flotec ejector kit FP4800.
Step 4. 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.
Step 5. 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.
You have just completed the well plumbing for your new deep well jet
pump. Please go to Page 8 for discharge pipe and tank connections.

Step 3. Install ejector kit FP4855 with a Series 4200, or kit FP4875 with a
Series 4300 pump (kits are sold separately). 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 4).
NOTICE: Always replace the ejector when replacing the pump in a
shallow well installation.
