What to do if my Flotec FP4212j-08 Water Pump does not deliver water to full capacity?
- M
  martintiffanyAug 18, 2025
  If your Flotec Water Pump isn't delivering water to its full capacity, the water level in the well might be lower than estimated, potentially requiring a new nozzle and venturi combination. If steel piping is used, corrosion or liming could be causing excess friction; consider replacing it with plastic pipe or new steel pipe. Also, ensure the piping isn't too small, as using larger piping could resolve the issue.

What to do if my Flotec FP4212j-08 motor will not run?
- E
  Eduardo BlackwellAug 20, 2025
  If your Flotec Water Pump motor isn't running, first ensure the disconnect switch is on. Then, check the fuse and replace it if blown, or reset the circuit breaker if it has tripped. Also, examine the wires at the motor to ensure they are correctly connected and tightened. Finally, the pressure switch contacts might be dirty, in which case you should disconnect the power and file the contacts with an emery board or nail file.

What to do if my Flotec FP4212j-08 motor runs hot and overload kicks off?
- T
  Taylor WintersAug 26, 2025
  If the motor of your Flotec Water Pump runs hot and the overload kicks off, it could be due to incorrect wiring. Refer to the wiring instructions. Also, low voltage could be the cause, so check with your power company. Finally, if the pump cycles too frequently, consider installing heavier wiring if the current wire size is too small (refer to the Electrical/Wiring Chart).

What to do if my Flotec Water Pump motor runs but no water is delivered?
- J
  James ReeseAug 28, 2025
  If the motor of your Flotec Water Pump runs but no water is delivered, consider these possibilities: * If it's a new installation, the pump may not have picked up prime. Re-prime it according to the instructions. * The pump may have lost prime; check all connections on the suction line and shaft seal. * The foot valve or strainer could be plugged, requiring cleaning. * The ejector or impeller might be plugged; clean them as necessary. * A check valve or foot valve could be stuck shut, in which case, replace it. * Pipes might be frozen; thaw them. * The foot valve and/or strainer could be buried in sand or mud; raise them above the bottom of the water source. * The water level may be too low for a shallow well setup; if it exceeds 25’ (7.6M), a deep well pump is needed.

Why does my Flotec FP4212j-08 have air spurts from faucets?
- H
  Hannah RiveraAug 30, 2025
  If you're experiencing air spurts from the faucets connected to your Flotec Water Pump, it could be due to several reasons. The pump might be in the process of picking up prime; once it does, it should pump solid water without air. There could also be a leak on the suction side of the pump; check the joints for leaks using soapy water. Another possibility is that the well is gaseous; in this case, consult the factory about installing a sleeve in the well. Lastly, it could be due to intermittent over-pumping of the well, where the water is drawn down below the foot valve; if possible, lower the foot valve or restrict the pump discharge.

How to troubleshoot a Flotec FP4212j-08 motor that will not run?
- T
  Terri MasonSep 4, 2025
  If your Flotec Water Pump motor isn't running, start by checking if the disconnect switch is turned on. Then, inspect the fuse and replace it if it's blown, or reset the circuit breaker if it's tripped. If these steps don't resolve the issue, the starting switch might be defective and needs replacement after you DISCONNECT POWER. Also, examine the wires at the motor for looseness, disconnections, or incorrect wiring referring to wiring instructions. Remember to DISCONNECT POWER before checking and tightening any wiring to avoid electric shock.

Why does my Flotec Water Pump motor run hot and the overload kicks off?
- M
  Michael HodgesSep 12, 2025
  If your Flotec Water Pump motor runs hot and the overload protection activates, it could be due to several reasons. First, refer to the wiring instructions to ensure the motor is wired correctly. Also, check the supplied voltage to ensure it is not too low. Contact your power company and install heavier wiring if the wire size is too small. Finally, if the pump cycles too frequently, refer to the section on too frequent cycling.

Why am I getting air spurts from the faucets when using my Flotec FP4212j-08 Water Pump?
- A
  Andrew DiazSep 14, 2025
  If you're experiencing air spurts from faucets when using your Flotec Water Pump, it could be due to the pump picking up prime; once the pump has picked up prime, it should pump solid water without air. Another cause could be a leak in the suction side of the pump, where the suction pipe is sucking in air. Check the joints for leaks using shaving cream. If the well is gaseous, consult the factory about installing a sleeve in the well. Lastly, intermittent over-pumping of the well, where the water is drawn down below the foot valve, can cause air spurts; lower the foot valve if possible, otherwise restrict the pump discharge.
