PUMP iNStallatiON
NOticE: Use only PTFE pipe thread sealant tape
for making all threaded connections to the pump
itself. Do not use pipe joint compounds on plastic
pumps: they can react with the plastic in the pump
components. Make sure that all pipe joints in the
suction pipe are air tight as well as water tight. If the
suction pipe can suck air, the pump will not be able to
pull water from the well.
1. Bolt pump to solid, level foundation.

NOticE: Install pump as close to well head as
possible. Long piping runs and many fittings create
530 0405
friction and reduce flow.
NOticE: For long horizontal pipe runs, install a
priming tee between check valve and well head as
shown in Figure 6. For driven point installations, install
a check valve as shown in Figure 6. Be sure check
valve flow arrow points toward pump.
Use schedule 80 or iron pipe. See "Well Pipe
Installation" for more information.
