My flotec pressure tank seems to be waterlogged, how do I recharge it?

If your pump is turning on by itself every 10-15 minutes for a brief period when no taps are open, it may indicate a potential issue with the water system or the pump itself. Here are some common causes and troubleshooting steps:
1. **Pressure Tank Issues:**
Check the pressure tank in your water system. A malfunctioning pressure tank or a tank with inadequate air pressure can cause the pump to cycle frequently. Ensure that the pressure tank is properly pressurized according to the manufacturer's specifications.
2. **Water Leaks:**
Inspect your plumbing system for any leaks. Even a small, slow leak can cause the pressure in the system to drop, triggering the pump to turn on periodically. Check for visible leaks and listen for any sounds of running water when all taps are off.
3. **Faulty Check Valve:**
The pump may be turning on due to a faulty check valve. The check valve is designed to prevent water from flowing back into the well or water source when the pump is off. If it's not functioning correctly, water may flow back, causing the pump to cycle.
4. **Waterlogged Pressure Tank:**
If the pressure tank is waterlogged, it can lead to frequent cycling of the pump. You may need to drain and recharge the pressure tank to resolve this issue.
5. **Faulty Pressure Switch:**
The pressure switch is responsible for turning the pump on and off based on water pressure. A malfunctioning pressure switch can cause the pump to cycle erratically. Check the pressure switch for proper adjustment and functioning.
6. **System Overpressurization:**
Excessive water pressure in the system can also cause the pump to cycle frequently. Check if the pressure relief valve is functioning properly and that the system pressure is within the recommended range.
7. **Electronic Control Issues:**
If your pump system has electronic controls, there could be issues with the control panel or the pump's electronics. Check for error codes or indicators on the control panel and consult the pump's manual for troubleshooting steps.
8. **Professional Inspection:**
If you're unable to identify the cause of the issue or if the pump continues to cycle unexpectedly, it's advisable to seek the assistance of a professional plumber or pump technician. They can perform a more thorough inspection and address any underlying problems.
Addressing the issue promptly is important to prevent unnecessary wear and tear on the pump and to ensure the efficiency of your water system.

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.

Some ideas on checking the pressure tank.

check the foot valve for leaks it at the end of the pipe in the well also if its newer than 30 years there is a cupler where the horizontal pipe meets the vertical on at the well head

I am going to take a stab at this it sounds like the bladder has gone bad it the expantion tank. Try letting some air out of the bladder tank and see if you get any water if you do then the bladder has gone bad the tank will need replaced. After the replacement turn the limit switch back to normal settings. You can also tap on the tank to see if it is full of water.

Hi,
Those pumps will reach 50# when brand new, but soon the parts wear and then they will not make that pressure anymore...
Instead of replaceing the pump, just back the pressure down a tick or two to get it to shut off and not waste your electric....

Well Pressure Switch Adjustment Water Well Problems

Maybe your check valve is letting water go back down the well.

Troubleshooting steps pg 13 in manual list several things.
Check air valve for leaks.
Flowtec has a customer service number:
1-800-365-6832

The manual says: "Your new pump has a 30/50 PSI
switch, so adjust the tank pre-charge pressure to 28 PSI.:
But the manual does not say or show how to adjust pre-charge pressure.
The 30/50PSI means the pump turns on when pressure falls to 30, and then runs until pressure rises to to 50. So the switch is preset and not adjustable.

check your pressure tank. It sounds like it is water logged. This means there is no air pressure in it. If you're cut in pressure is set at 30 pounds you must have 30 psi of air pressure in the pressure tank.

If the pressure does not get pass 30 psi, then check for leaks along the pipelines and on the tank itself. An air leak on the top portion of the tank can cause the pressure not to trigger the pressure switch. Use soap bubbles to detect any air leak. Although a stuck pressure is not more likely the problem, check it also.

These holding tanks are pre charged with air which in turn pressurizes the water. The tank has a bladder and an air valve on top. The pre charge ,over time, loses pressure, and the tank has to be pressurized again.

• The well pump needs to be turned off.
• The water has to be drained from the tank
• Air is put into the tank from the air valve on top of the tank, and is measured with a tire air gauge.
• The pre charge pressure is set to two psi below the pump cut in pressure.
• In other words if your pump kicks on at 30 psi, the pre charge pressure is set at 28 psi. If the pump kicks in at 20 psi, the pre charge is set at 18psi, etc.
• After you pressurize the tank, turn water back on.
• If water comes out of air valve on top of tank, then the bladder is ruptured and you need a new tank.
• Hope this helps!
