DUG WELL, CISTERN, LAKE AND
SPRING INSTALLATION (FIGURE 12 ON
PAGE 11)
1. Install a foot valve on inlet pipe and
lower into water.
The foot valve
SHOULD be at least
18” from the bottom of the well or sand
or sediment MAY be drawn into the
system.
NOTE: When a lake is used as a water
supply, make sure the inlet pipe is deep
enough to be submerged at all times.
Slope the horizontal piping upward
toward the pump to prevent trapping air.
The pipe must be removed during winter
months or protected against freezing.
Protect the pipe from damage from
swimmers and boats.
Install a screen
around the inlet pipe
to prevent the entrapment of swimmers.
SHALLOW WELL PUMP WITH
CONVENTIONAL STORAGE TANK
1. Install air volume control on tank.
2. Connect the copper tube from the air
volume control to the uppermost 1/8”
NPT opening on the side of pump. Be
sure the connections are tight. Leaking
can cause the pump not to prime.
3. Install a valve and an isolator hose
between the tank and the house
plumbing to aid in pump removal for
servicing and for reducing the noise
transmitted to the house through the
piping.
4. Provide a hose bib (faucet) at the
lowest point in the system to drain
the system for service or storage.
SHALLOW WELL PUMP WITH
PRECHARGED STORAGE TANK
1. Shut off the power to the pump.
2. Open the faucet nearest the tank and
allow all water to drain from the tank.
3. Measure the tank precharge at the
valve stem using a tire pressure gauge.
4. If necessary, precharge with an air
pump to 28 - 30 psi on 1/2, 3/4 and 1
HP pumps.
5. Slope the horizontal pipes upward
toward the pump to prevent trapping
air. If the horizontal distance exceeds
25 feet, see Chart 2 on page 3 for the
recommended pipe size.
