20 Most Recent Flotec FP217810 Submersible Well Pump Control Box Questions & Answers

That rating is deceptive. Horsepower equates to amps and they are two different ratings. You should not use a 1/2 HP for a 3/4 rated motor.

possibly your pressure tank needs to be replaced

check your pressure switch to see if the points are closed if there open its not asking for water the box wont go bad very easy starting capacitor would be the part.

Electrical code requires both hots to be switched on a 230V supply, you can switch one hot and the pump will turn on and off but there will always be an existing electrocution hazard, not a good thing.

Even new pumps have faulty parts. It could be that the foot valve is defective.

No, this pump does not natively turn on and shut off based on pressure. You need to add a pressure switch and tank. Flotec has the manual for the FP5172 here: https://www.pumpagents.com/pdf/FlotecPumps/Flotec-FP5172.pdf . I hope this helps. Cindy Wells

Some ideas on checking the pressure tank. https://www.google.com/search?q=flotec+tank+is+running+on+and+off ..

Does this unit have a pressure switch? A lot of pressure switches have an adjustable cut-in / cut-out allowing you to change the nominal operating pressure. If it is only running a short time, you could adjust the pressure switch and see if it helps. **With the power off** make small adjustments, don't crank it.

How to Set the Pressure Regulator on a Deep Well Jet Pump

1. Install a pressure gauge between the pump and the control valve if one is not already installed. ...
2. Run the pump until the pressure has stabilized. ...
3. Adjust the discharge control valve to provide 20-psi back pressure. ...
4. Open a faucet to let water run near the pump. ...
5. Open the pump control valve slowly.

Ohhhh ya. Fun, fun, fun. But, there is a way. Watch this video from Joseph and Robert on the "easy way' to remove a stuck water pump impeller. How To Remove Stubborn Impellers

It sounds like your float is hanging up. Yes, it does sound like your pit is too small. If it is smaller than 18" in diameter, it is too small. A small pit is bad for the pump too because if it is raining hard, your pit will fill very quickly. Now when the pump runs, it will empty very quickly. On-off-on-off-on-off is very bad for the pump.This is what is known as short-cycling, and it will burn up your pump in no time because of the constant on/off cycles.

lol too much power for the pressure tank back off the flow or get a new pressure valve 50 psi is good pressure how big is the tank what is the gauge rated for all these \details need to be spoken in order to answer sounds like you want some water lol its sucking air too tank doesn't need air it has to be primed first tighten the bolt and now you have to use pipe sealant white putty to seal those nuts and bolts back up pump cant suck air

A number of Flotec pump manuals are available here: http://www.flotecpump.com/ResidentialResourcePage_resourcepage_ownersmanuals.aspx . The site lists a FP4022-10 pump with the direct link to the manual here: http://www.flotecpump.com/resources/images/514.pdf . For this type of pump, there should be a priming plug or priming tee. Remove the plug (or tee) and pour water into the pump. Keep adding water until the pump and all of the piping to the well is full of water. If a priming plug or tee was also added on the suction side of the pump, open that section and fill all of the piping on the suction side with water. Replace the plugs/tees then open a faucet in the house. Start the pump. After 2-3 minutes, turn off the pump if no water has come through the unit. Add more water through the priming plug or tee (or multiple plugs and tees). Then repeat closing the priming ports and start the pump after opening a faucet. Once the pump is actually pumping water, turn off the open faucet. Wait for the pump to shut off once it reaches full pressure. Open one or two faucets to check that the pump is properly sensing the pressure changes and maintaining system water pressure. If the unit didn't pull water from the well, check the piping for air leaks. See the full trouble-shooting guide in the manual. Page 9 has the priming information and page 10 has the trouble-shooting guide. I hope this helps. Cindy Wells

from a electrical motor re-winder or repair shop take the old unit with you to get a comparable capacitor voltage /farrad reading

Usually it is the pump shaft seal located where the motor shaft turns the pump. It consists of two ceramic faces that are held together with a spring:

Sounds like you need to set the water level switch to shut off or the switch could be stuck in the on mode. Move the switch up and down and see if it comes on and push down to go off. It probably just needs setting. There should be a screw to set it.

could be a short in the wire or A short in the switch itself or the motor is just bad

Check your intake hose connections and it may have a screen inside the water connection at the pump, and there may also be one on the discharge side, make sure they are clear and clean. Check the impeller for any blockage.

It could be one of three things, the inlet is plugged, the outlet is plugged or the pump is bad. I am assuming it worked properly until this failure. I am guessing but it has to be one of those three.
