feet below the lowest drawdown water level. All hose
clamps should be tightened securely. If galvanized steel
piping is used, screw first lengths of pipe into the injector
foot valve assembly using pipe sealant on male threads
only. Lower the jet and pipes into the well. Fill pipes with
water to check for leaks and to speed priming. Installation
should be made with clean pipe free of burrs.

CONTROL VALVE FOR DEEP WELL OPERATION
A control valve is required for all deep well installations.
See Figure 3. When installed, the control valve will
need to be adjusted to assure optimum performance as
described below:
(a) loosen hex nut.
(b) rotate valve stem to closed position.
(c) prime pump (completely fill pump and piping
with water).
(d) start pump.
(e) open valve stem slowly to regulate discharge into
service line. Observe pressure gauge and continue
to open valve until pressure starts dropping off and
a noticeable reduction in flow is observed, then
turn valve stem in opposite direction until flow and
pressure on gauge has stabilized.
(f) tighten hex nut.
PRIMING (DEEP WELL)
The motor should not be started until pump is primed.
To prime the pump, remove the priming plug or discharge
plumbing line and fill pump and piping with water.
Replace plug or discharge line. Open faucet in water
system, then release nut at bottom of control valve so

you can turn valve to closed position. Turn on pump and
let pressure build in system, then gradually open control
valve until pump is delivering adequate amount of water
without losing prime and without excessive noise. On all
installations, it is best to check if your water runs clear
before you connect complete system. Let pump operate
until water runs clear. However, if after a reasonable time
water continues to run sandy or dirty, check with your
dealer for further instructions.

DISCHARGE PIPE SIZES FOR DEEP
WELL INSTALLATIONS
When the pump is located at a distance from points of
water use, it is necessary to increase the discharge pipe
size in order to reduce friction loss. The Discharge Pipe
Size table shows the recommended sizes.
