1. Drain and remove the old pump. Check pipe for scale, lime, rust, etc.,
and replace it if necessary.
2. Install the control valve and pressure gauge in the pump body (see
Figure 1).
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).

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.
