3. Mount the pump as close to the well as possible.
4. Connect two pipes (1" drive, 1-1/4" suction) to the ejector and lower the ejector into the well until it is five feet from the
bottom. It should also be at least 10 feet below the well's water level while the pump is running in order to prevent the pump
from sucking air.
5. Install a sanitary well seal and connect the ejector piping to the pump. Use steel nipples through the well seal with flexible
poly pipe to avoid crushing the plastic pipe when tightening the seal.
6. Support the pipe so that there are no dips or sags in the pipe, so it doesn't strain the pump body, and so that it slopes
slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction
pipe joints with PTFE pipe thread sealant tape or a PTFE-based pipe joint compound. Joints must be air and water-tight. If
the suction pipe can suck air, the pump cannot pull water from the well.
You have just completed the plumbing for your new double pipe deep well jet pump. Please go to priming.
Priming
Caution: Risk of burns. Never run pump dry. Running pump without water may cause pump to overheat, damaging seal
and possibly causing burns to persons handling pump. Fill pump with water before starting.
Warning: Risk of explosion and scalding. Never run pump against closed discharge. To do so can boil water inside pump,
causing hazardous pressure in unit, risk of explosion and possibly scalding persons handling pump.
1. Pull out the pressure tube from the 90° elbow insert. Unthread and remove the elbow insert from the pump body.
