Installation 5
Risk of electric shock and
explosion . Disconnect all power to pump and
bleed all pressure from system before working
on pump, tank, or piping.
For jet pump installation, remove AVC tube
from port in pump body or jet body and plug
port (see Figure 3). New pumps come with
plug installed.
NOTICE When working on submersible pumps
in wells, be sure safety rope is solidly connected
to pump and securely anchored at the well
head at all times. Do not drop the pump down
the well!
Bleeder Orifices
For submersible pump installations, there may
be bleeder orifices in the vertical discharge
pipe. They must be removed and the tees
plugged when a pre-charged tank is installed
in the system. To do this, raise the pump and
discharge piping enough to bring the bleeder
orifices clear of the well. Remove the bleeder
orifices from tees and replace with plugs (see
Figure 4). Bleeder orifices may be any of several
sizes. Have a supply of 1/2”, 3/4”, and 1” plugs
available. Replace pump and reconnect the
discharge pipe.
Adjusting Tank Pre-charge
In areas where temperature is high for long
periods of time, tank pre-charge pressure may
increase. This may reduce tank drawdown
(amount of water available per cycle). If this
occurs, adjust pre-charge pressure according to
Chart 1.
Flush all air out of piping system and water
reservoir portion of pre-charged tank.
Adjustment of tank pre-charge is required on
new installations, pumps requiring re-priming,
and pumps disassembled for service.
Adjust tank precharge as follows:
1. Open faucets furthest from tank and run pump.
2. Run pump until sputtering stops and steady
stream of water flows.
3. Open and close faucets repeatedly until all air
has been removed.
4. If stream does not become steady, air may be
leaking into system; check for leaks in piping
on suction side of pump.
NOTICE To prevent waterlogging, check tank air
charge annually.
To Check Tank Air Charge
If drawdown decreases significantly, check
as follows:
1. To check air charge in tank, shut off electric
power to pump, open faucet near tank, and
drain completely.
2. At air valve, check tank air pressure with tire
gauge. See Chart 1 for correct pressure setting.
If needed, adjust tank pressure up or down.
3. Use soap or liquid detergent to check for air
leaks around air valve. Continuous bubbling
indicates leak. If necessary, release air pressure
and install new core in air valve, (same type
used for automobile tubeless tires.)
