Preparing to Start the Pump – Shallow Well
8
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 12). 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 pip-
ing 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 pro-
cedure.
Step 5. After the pump has built up pressure in the system and shut off,
check the pressure switch operation by opening a faucet or two and
running enough water out to bleed off pressure until the pump
starts. The pump should start when pressure 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.
Open control valve
as far as possible
and fill pump and
piping through
priming port
or priming tee.
