Pump Troubleshooting
Pump Will Not Start Check:
• Fuse or breaker
• For correct voltage (±10%) and electrical
connections
• Pressure switch operation and correct
voltage at switch or motor wires (as
equipped).
•
Rectifier or motor for open or grounded
circuit
Drive assembly locked
Will Not Prime Check:
(No discharge/motor runs)
• Out of product
• Strainer for debris
• Inlet tubing/plumbing; severe vacuum leak
• Inlet/Outlet tube severely restricted
(kinked)
• Debris in pump inlet/outlet valves
• Proper voltage with the pump operating
(±10%)
• Pump housing for cracks
Leaks From Pump Head Or Switch:
• For loose screws at switch or pump head.
• Switch diaphragm ruptured or pinched
•
For punctured diaphragm if fluid is
present at bottom drain holes.
Pump Will Not Shut-Off Check:
(Pressure switch equip.)
• Output line closed and no leaks
• For air trapped in outlet line or pump head
• For correct voltage to pump (±10%)
• Inlet/Outlet valves for debris or swelling
• For loose drive assembly or pump head
screws
• Pressure switch operation/adjustment
incorrect. Refer to relevant pump manual
for differential and pressure adjustment
procedure.
Noisy / Rough Operation Check:
• Mounting feet that are compressed to
tight
• For loose pump head or drive screws
• Does the mounting surface multiply noise
(flexible)
• Is the pump plumbed with rigid pipe
causing noise to transmit
Pump Wiring
Important:
Use 14 gauge stranded wire up to
6 metres from power source and 12 gauge up
to 18 metres from power source.
Connect Red to Positive (+) terminal and Black
to Negative (-) terminal.
