WARNING:
PVC pipe is generally not recommended for compressed air service.
Cautions
The following suggestions are offered to reduce the complications involved in assembly and
installation.
• Cover the hose ends with tape if they are being pulled through trenches. Be sure the ends
of the hoses that connect to the air compressor and fluid discharge have the correct fitting
leading out of the well. If you are unsure, look at the respective fittings on the pump.
• Blow out all water and particles from compressed air conduits (trunk lines, sensor hoses, air
supply hoses etc.) and fluid lines for at least 10 seconds after the water and particles exit
before connecting them to the system.
• When running hoses in conduit, include a rope to pull additional hoses in case they are
needed at a later date
• If solid metal piping is used for compressed air conduit, it is advised that an air filter or a
"Y" strainer with a fine mesh screen (80 mesh or finer) be placed at the downstream end
of the piping. Metal flakes, rust, galvanizing material, dirt, etc. can be dislodged from such
metal piping and travel to the pump.
