use,the discharge pipesizeshouldbe
increased to
reduce pressure losses caused by friction,
o Up to 100' run: Same size as pump discharge port.
= 100' to 300' run: Increase one pipe size,
= 300' to 600' run: Increase two pipe sizes.

Pump/Piping installation
PUMP INSTALLATION
NOTICE: Use Teflon tape supplied with the pump for
making all threaded connections to the pump itself Do
not use pipe joint compounds on the pump: they can
react with the plastic in the pump components.
1, Bolt pump to solid, level foundation
2. Support all piping connected to the pump,
3. Wrap t-1/2 to two layers of Teflon tape clockwise (as
you face end of pipe) on all male threads being
attached to pump.
4o Tighten joints hand tight plus 1-1/2 turns° Do not
overtighten.
NOTICE: Install pump as close to well head as possible.
Long piping runs and many fittings create friction and
reduce flow.
NOTICE: For long horizontal pipe runs, install a priming
tee between check valve and well head as shown in
Figure 5, Page 4, For driven point installations, install a
check valve as shown in Figure 6, Page 4. Be sure check
valve flow arrow points toward pump
Use schedule 80 or iron pipe, See "Well Pipe Installation"
