Preparing to Start the Pump – Shallow Well
9
Never run pump against closed discharge. To
do so can boil water inside pump, causing hazardous
pressure in unit, risk of explosion and possibly scalding
persons handling pump.
Never run pump dry.
Running pump without
water may cause pump to overheat, damaging seal and
possibly causing burns to persons handling pump. Fill
pump with water before starting.
Step 1. Open the control valve as far as possible (see
Figure 15). Then remove the priming plug from
the pump and fill the pump, fill all piping
between the pump and the well, and make sure
that all piping in the well is full. If you have also
installed a priming tee
in the suction piping,
remove the plug from the tee and fill the suction
piping.
Step 2. Replace all fill plugs. Leave the control valve
open (in a shallow well installation, the control
valve always stays open).
Step 3. Power on! Start the pump. The pump should
pump water in two or three minutes.
Step 4. If you don’t have water after 2 or 3 minutes, stop
the pump and remove the fill plugs. Refill the
pump and piping. You may have to repeat this
two or three times in order to get all the trapped
air out of the piping. The control valve remains
open throughout this procedure.
Step 5. After the pump has built up pressure in the sys-
tem and shut off, check the pressure switch oper-
ation by opening a faucet or two and running
enough water out to bleed off pressure until the
pump starts. The pump should start when pres-
sure drops to 30 PSI and stop when pressure
reaches 50 PSI. Run the pump through one or
two complete cycles to verify correct operation.
This will also help clean the system of dirt and
scale dislodged during installation.
