INSTALLATION
Physical Installation

4. Find the total length needed for 1 ¼- and 1-inch PVC pipe and couplings.
• Measure the distance from the top to bottom of the well and subtract 5 feet.
5. Assemble the 1 ¼- and 1-inch PVC pipes and couplings.
• The 1-inch PVC pipe should be cut two inches shorter than the 1¼-inch pipe.
IMPORTANT: Ensure any burrs or shavings from cutting the pipes are completely removed to pre-
vent damage to the pump.
6. Firmly clamp the unfinished pipe end with a pipe clamp 1 foot (30 cm) from the top of the pipe.
7. Lower the foot valve end of the piping assembly into the well.
8. Install the well seal and a well vent tube.
• Ensure the foot valve is suspended 4 feet (1.2 m) from the well bottom.
• The 1 ¼- inch pipe should extend 1 foot (30 cm) above the seal.
• The 1-inch pipe should extend 10 inches (25 cm) above the seal.
9. Attach a 90° elbow to the end of each pipe.
Pump Location
• Install the pump indoors in a clean, dry, and ventilated location shielded from direct sun and precip-
itation.
• Provide adequate room for future servicing, protection from freezing temperatures, flooding, and
equipment drainage.
• Bolt unit down evenly on a good foundation, preferably concrete, to prevent unnecessary stresses
from pump movement.
• Install as close as possible to water source to minimize suction piping length.
• Keep motor-operating area as dry as possible.
Piping Connections
Well Piping to Pump
1. Install a pressure gauge into the ½-inch NPT hole on the front of the casing, opposite the pressure
switch.
IMPORTANT: For driven wells, have an electrician replace the pressure switch with a low pressure
cut-off.
• A pressure gauge is not necessary for all applications. Install if included or desired.
2. Attach a 1¼-inch male PVC adapter to the top hole in pump casing.
IMPORTANT: Do not over-tighten.
3. Install piping between the pump and the well piping.
