Preparing to Start the Deep Well Pump 9
Risk of burns . 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.
Risk of explosion and scalding . 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.
1. Open the pressure regulator as far as possible without backing it out
of the regulator body. Then remove the regulator 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 (see Figure 10).
2. Replace all fill plugs and close the pressure regulator completely
(Figure 11).
3. Power on! Start the pump and watch the pressure gauge. The pressure
should build rapidly to about 50 PSI as the pump primes.
4. After 2 or 3 minutes, the gauge should show pressure. If not, stop the
pump, remove the fill plugs, reopen the control valve, and 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. Don’t forget to close
the control valve each time before you start the pump.
5. When pressure has built up and stabilized at about 50 PSI, slowly open
the control valve (see Figure 12) and let the pressure drop until the
pressure gauge needle starts to flutter or drops to 0. When the needle
flutters or drops, close the valve just enough to stop the flutter or bring
the needle back to a stable pressure (see Figure 12). Your pump is now
operating at its most efficient point.
6. 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.
Congratulations on a successful installation.
