Question about Plumbing

Open Question

I have a Flotec FP4112 08 pump, and I'm having an issue. The pressure switch is functioning, but when the power gets to the pump it just makes a loud humming noise. I took the cover off the end of the pump, and the shaft turns freely (I was told by a friend that it may have seized up, but it doesn't look like that's it). I have found some info that leads me to believe it may be the start capacitor, but I can't find it's location. Another person told my dad that there are electrical "points" inside the motor that could be stuck. We are going to be taking it apart, and I'm pretty much just wondering what to look for and what to check. Thanks in advance!!

SOURCE: No suction at pump intake

Put a vacuum gauge into the front drain plug port with the pump installed and see how much vacuum it draws. If it is low get the pump or lines repaired, if not have a well driller check the well point.

Gould water pump not comming on


Check for power to the pump then check again after the built in pressure switch. You can get the manual from Flotec at: http://www.flotecpump.com/ResidentialResourcePage_resourcepage_ownersmanuals.aspx

If the motor buzzes then there is probably a bad start capacitor.

Hi Eglenni,

Here are the specs for your pump:

Thermoplastic Shallow Well Jet Pump 3/4 HP. This new revision of an "old hand" provides good pressure pumping from wells where the depth-to-water is 25' or less.

BODY CONSTRUCTION: Thermoplastic
HORSEPOWER: 3/4
MAXIMUM CAPACITY: 12 GPM
FLOW at 10' LIFT and 40 PSI: 9.7 GPM
MAX LIFT: 25'
MAXIMUM PRESSURE: 78 psi
PRESSURE SWITCH SETTING: 30/50
SUCTION PIPE SIZE: 1-1/4" NPT
DISCHARGE PIPE SIZE: 1" NPT
AMP DRAW (full load): 6.1 amps on 230v / 12.2 amps on 115v
VOLTAGE: 230v / 115v, 60 Hz
RECOMMENDED BREAKER: 15 amp on 230v / 20 amp on 115v
MAXIMUM WATER TEMPERATURE: 140 °F (60 °C)
=========================================
Note that this pump can be operated at 115 volts or 230 volts (A/C) It may have come wired for 230 volt use from the vendor.

Make sure the pump is piped correctly.


There should be a wiring diagram either on the pump or in the literature so you can check to see how the pump is wired.

MAKE SURE
you have the pump wired for 115 volt use in your case. Also make sure the wire size is #12 awg for the power wiring.
Make sure all connections are tight. If you have an amprobe (an instrument that measures electric current) you can check to see how many amps the pump is pulling when it runs.

You said your old pump was 1 HP. This Flotec pump is 3/4 horse so there could be some pump performance loss depending on the well depth and length of the piping runs.

Here's the link to the website for the pump. There are additional resources available on the website:

We have a flotec well pump, less than a year old. The pump is working fine, and is primed. The switch doesn't appear to be working. Is this a difficult item to replace? Home Depot sells the pump and...


To replace the switch, shut off power, remove wires noting all wire locations.
You may have to relieve pressure in the system by using water until the surge tank is empty.
I'm not sure about that.
You do have to either remove the switch from the piping by unscrewing it or remove the piping from the switch by removing the connector and unscrewing the connector from the switch.
Assembly is the reverse. You should use teflon tape of dope on the screw connection below the switch.
The procedure should take about a half hour but you won't have any water during this time.

How do i set the low pressure on the flotec switch


your pump should have a 20lb seperation ie. pump turns on at 20lb and off at 40lb or on at 50lb off at 70lb. under the cover of the switch theres two screws with springs under them.dont mess with the small one.the large one if you screw it down (right) will increase the pressure while maintaining the 20lb separation. one thing to keep in mind its fine to adjust the pressure BUT at the same time the air pressure in the tank needs to be adjusted to two lbs below the cut in pressure of the pump.

I believe the directions are in the top of the cover of the switch

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.

Why wont my Jet pump shut off?


Is the little pipe that connects to the pressure switch clear?

I suggest you remove it and blow through it to make sure it is clear. If the pressure is getting to the switch, it has to shut off ... your switch should be set around 30/50 (on at 30 - off at 50)

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,
Tom

Flotec Sprinkler Pump not priming


it might be that the pump is prewired at 230 volt and you are running a 115 power supply to it, if motor just humms and little water comes out this might be your fix
