Replacing An Existing Pump - Simer 3305P Owner's Manual

Replacing an Existing Pump

DEEP WELL
Hazardous voltage. Disconnect power to
pump before working on pump or motor.
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).
Figure1: Install Control Valve and Gauge
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 ejector kit FP4800 or 29660.
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.
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.
