If the water supply pipes become clogged, the pump will short cycle. A clog in the water supply creates high water pressure very quickly. The best way to check for this is to check the water filter. If it's dirty or blocked, replace it, and you may restore function.... read more ›

Your gas pump keeps stopping before your tank is full because the pump is set up to stop when it detects a certain level of gasoline in the tank. This is to avoid overfilling and spills because the nozzle on the pump is gets blocked, preventing it from pumping more fuel into the tank.... continue reading ›
When air gets trapped in pipes, it can cause fluctuating, and spluttering water pressure as the air and water move through the pipes. Air trapped in pipes acts as a valve, causing water flow to stop and start in fits and bursts.... see more ›
Directly, the motor is stopping due to the overloads tripping. That could be due to… bad motor windings drawing excess current. Bad motor bearings causing excess load and excess current.... read more ›
- Repair the tank air volume control.
- Drain the water tank and let air re-enter the tank.
- Drain the water from the tank and use the air inlet valve to recharge air back into your tank. The air charge should be 2 psi lower than you pump cut-on pressure.
- Mechanical seal leakage. ...
- Process issues. ...
- Bearing issues. ...
- Impeller wear and tear. ...
- Coupling-related issues.
If a pump is taking its suction from a tank with low liquid levels, the formation of vortices can draw air into the suction line and hence the pump. Vorticing can be eliminated, by installing a low liquid level sensor to turn off the pump.... continue reading ›
There are many things that could lead to no water supply even with your water pump running. Some of the possible issues include: A blocked sediment filter or a failing filtration system. Low water table caused or overusing your water supply.... see details ›
In simple terms, if your pump is drawing down more current than the breaker has capacity for, then it could cause it to trip out. Essentially, the breaker is doing its job as it detects that too much current is being drawn than it can safely handle.... see details ›
The gas pump nozzle shuts off due to the way it is designed. When the nozzle shuts off as you're trying to use it, this does not necessarily mean that it is malfunctioning. Actually, it has a mechanism that is supposed to shut off the fuel supply for safety reasons.... continue reading ›
Basically, the gas is coming out of the gas pump at a pressure that is too fast for the car to take in. If the air vapors do not get out fast enough and the tube gets covered by gasoline, a vacuum forms inside the nozzle which will automatically switch off the flow of gas into your tank.... read more ›
Excess air will just be discharged: Provided that your water tank is one that does not use an internal bladder to keep water separate from air, if you have put more air into the pressure tank than necessary, the excess air will simply squirt out of various faucets the next time you run water and then the problem will ...... view details ›
Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi. If your well tank is on a 40/60 pressure switch, your pressure setting should be 38 psi.... see details ›
There can always be a rule of thumb of one minute on and one minute off. The motor is much more efficient with two minutes of shut off after two minutes.... read more ›
How Often Should A Pressure Tank Cycle. A pressure tank should cycle once every 24 hours. If you have a large pressure tank, you may be able to draw down on the water volume for 30 minutes to an hour before turning it on. You will be able to fully relax for 45 to 2 minutes with a standard pressure tank.... see details ›

Short cycling of a water pump means that the water pump or "well pump" turns on and off too rapidly or too frequently when water is being run in the building. "Short cycling" means switching on and off every 30 seconds or less.... read more ›
Short cycling is when a pump turns on and off too rapidly. Not only can short cycling result in pump failure, but it can harm the rest of your system as well. Short cycling can occur for a number of reasons. One of most common reasons for short cycling is a loss of air in the water pressure tank.... read more ›
- Turn off the power to your switch.
- Remove the switch from its housing.
- Use a soft brush to clean any dirt or debris from the switch.
- Rinse the switch with clean water.
- Reattach the switch to its housing.
- Turn on the power to your switch.
Three problems are possible. Either the flow is too low, and therefore the head is too high, or the head is too low (indicating that the flow is too high). When considering head and flow, remember that the pump is correctly operating on its curve. Therefore, if one is too low, the other must be too high.... see details ›
Shutting Down Centrifugal Pumps
For low to medium specific speed pumps (below values of approximately 5,000), close the discharge valve prior to stopping the pump. This takes the load off the motor and, if any check valves leak, it may prevent reverse flow through the pump.... see details ›
