PROBLEM
Pump will not prime.
Pump delivers water for a period
of time, then stops pumping.
Pump does not deliver rated
capacity.

(CAUTION: SHUT OFF POWER TO PUMP)
• Not enough water. Stop motor, remove pressure gauge bushing, and fill case and suction line
with water.
• Pump wired incorrectly.
• Plugged venturi tube or nozzle.
• Foot valve is sitting in sand or mud, or is stuck shut, or leaks.
• Low well water level. In deep wells, the ejector as well as the foot valve must be below
water level.
• For the RC10 & RC5, the diffuser O-ring seal may be improperly positioned.
• Air leaks. Check all connections for airtightness.
• Low well water level. Use a water-level tester while pump is operating.
• Plugged venturi tube, nozzle, or impeller parts.
• In deep wells, the regulator may be set incorrectly. See Step 14 in the 4" diameter Deep Well
Installation Instructions.
• Plugged venturi or nozzle.
• Faulty pressure gauge resulting in false readings.
• In deep wells, the operating pressure may be too high. See Step 14 in the 4" diameter Deep
Well Installation Instructions.
• Low well water level. Use a water-level tester while pump is operating.
• For the RC10 & RC5, the diffuser O-ring seal may be improperly positioned.
• Oversubmergence of ejector. In deep wells, if ejector is more than 10 feet below pumping
level, pumping capacity is reduced.
• In deep wells, the ejector may have improper size and depth setting.
• Motor voltage does not match power supply voltage. See pages 2 and 3.
• Improper wire size. See Wire Size Guide on page 3.
• Impeller is rubbing against pump case.
• Impeller neck is worn.
• Defective pressure switch.
• For the RC10 & RC5, the O-ring seal may be improperly positioned.
• Tank precharge pressure too high. Tank precharge pressure must be 1–2 pounds less than
switch turn-on setting.
• In deep wells, the water level may be going below limit of ejector. Use water-level tester
while pump is operating.
• Galvanized storage tank is waterlogged.
• Leaky foot valve.
• Too much tank pressure.
• If within Warranty, return pump/motor unit to place of purchase (with proof of purchase)
for exchange.
