and replace it if necessary.
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 FP520-100-P2, included with
the pump.
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. See Figure 2.

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.
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 pump/tank system.

1. Drain and remove the old pump. Check the old pipe for scale, lime,
rust, etc., and replace it if necessary.
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.
Install the pressure gage in the plugged hole in the pump body (see
Figure 1).
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.
4. 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.
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.
6. 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.
