Question about Flotec Corrosion Resistant Shallow Well Jet Pump 1/2HP, 8GPM

1 Answer

I have a Flotec FP 4022-10 3/4 hp shallow well pump. It was working fine yesterday afternoon and then in the evening I had no water. I replaced the pressure switch and checked the pressure in the tank (it's set at 28psi). The pump will run for a couple of seconds and then cut off. I have primed it and still nothing. The pump also seems to be extremely hot. Any advice would be greatly appreciated.

    When you say "it's set at 28psi" you are talking about the air pressure on the bladder tank when there is no water in it, correct? From the sound of it, you have had a catastrophic pump failure or a bearing failure in the motor that has it locked up. How old is it? Warrenty? Are you able to disassemble it yourself?

    How old is the pump? and , is it a high use water system that you have, small or large family, lots of laundry, car washes ,etc, etc.? Your system works on 30-50 pressure?

If heating up, the motor thermal switch is opening to shut down the motor; this is by design. During the brief run time does it pump at all? It sounds as if there may be mechanical issues on the pump itself and the motor (from the extra draw) is heating up and shutting down. I'd look in to the pump to see if anything had failed within it.
I hope this may have helped,

I ask a question yesterday about a flotec 1 hp pump. How do I know if I need to rebuild the pump or if my well has got to low on water?

how deep is the well can you hear the pump working.or are you able to pull the pump up to inspect it.or can you place ahose down the well to be sure that water is down there,some pumps have a pressure sensor so when theres no water it switches of so as it does not opperate dry,because this will damage the seals in the pump,hoe this helps.

Hi there my flotec 1/2 hp shallow well jet pump has a crack in the casing how can i repair this until i can get a new pump?

If it is on the pressure side about the only repair would be to get it welded. If on the suction side you MIGHT be able to "V" it out slightly and use JB Weld or maybe even Bondo... Tose will NOT work on the pressure side however.

Flotec pump model FP 4112-08 will not pump over 35 psi

If it stops pumping at 35psi you need a new pressure switch. If it just continues to run but doesn't build more pressure the problem is more likely a plugged point or air getting in due to the water table dropping.

The foot valve (one way valve) is either very dirty and in need of cleaning, or it is defective and should be replaced. Don't wait, you're wasting a heck of a lot of electricity and wearing out the pump much faster than you should.
