- PUMP PRIME, REPEATED LOSS
What happens when a pump loses prime?
No water pressure due to lost pump prime: IF you have no water pressure, absolutely no water in the building water supply piping, and no water in the water pump itself, THEN we've lost prime and the one line or two line jet pump may be unable to bring water back from the well.
What causes a water pump to lose prime?
Debris blocking the suction strainer or foot valve is the most common cause. A blockage in the intake line can cause the water in the pump casing to overheat and literally boil out of the casing causing the pump to lose prime.
How do I know if my pump is missing prime?
If the water pump turns on but keeps running for a minute or two, check the water pressure gauges at the pump and tank. If the gauges are not rising in pressure (or if the water tank is not filling with water - is not getting heavier) then the pump has not been successfully primed.

Why is my water pump not building pressure?
The water pump may have suffered internal damage to a seal, bearing, or impeller. The motor will keep running but the pump is unable to develop normal pressures. "Damage" may include a broken impeller blade, scale or debris clogging the impeller or other pump components, or a failing pump seal or bearing.
Why is my water pump not pumping?
A leak in your system will cause both of these issues. Replace any leaking or damaged pipes and check the water level to make sure that your pump hasn't exceeded the well capacity. A faulty pressure switch will also cause the motor stay on or cycle too fast. Double-check the settings, and clean the contacts.
How much water does it take to prime a well pump?
When you first install your well pump, you need to prime it. You will need about one to two gallons of clean drinking water for this process since the water will ultimately be flowing from your pipes.
What does it mean to prime a pump?
Pump priming is the action taken to stimulate an economy, usually during a recessionary period, through government spending and interest rate and tax reductions. The term pump priming is derived from the operation of older pumps - a suction valve had to be primed with water so that the pump would function properly.
Why do we prime a pump?
The main objective of priming a pump is to remove the gas present. So, if the air or other gases present inside the pump casing and suction line, it must be primed before starting. But if the pump suction line and the casing are already filled with liquid during start-up, priming is not required.
What makes a pump self-priming?
What is Self-Priming? If a pump is located beneath the level of the liquid to be pumped, gravity and air pressure ensure that it is constantly filled with the liquid and there can be no ingress of air into the pump or suction line.

What happens if you clog a pump?
If something gets sucked up and clogs the piping or pump, you will experience poor flow. This isn’t as easy to diagnose as a crack or leak, but should be checked if you’re having priming problems. If you are in Wisconsin or Upper Michigan and can’t diagnose your pump priming problems, contact us.
What is self priming pump?
Self-priming pumps are designed to lift water from below the pump’s mounted location. One of the benefits to a self-priming pump is that it doesn’t require you to fill the suction piping with liquid first. If you tried that with a pump that was losing prime, or a regular centrifugal pump, you’d get a horribly choppy flow of water and air.
Does Gorman Rupp pump run dry?
If you’re unfamiliar, watch this quick 3-minute video that illustrates how a Gorman-Rupp self-priming pump works. It is important to know that just because self- priming pumps can pull up fluid, doesn’t mean they can run dry. Just like most other pumps, self-priming pumps need fluid in the casing before starting.
Can suction line spring a leak?
There are a variety of ways that the suction line can spring a leak. Most of the times this line is underground or in a hard to reach area, so the leak can go unseen. This is the first thing you should check if you’re experiencing priming issues.
Do self priming pumps need fluid?
Just like most other pumps, self-priming pumps need fluid in the casing before starting. If you were to run it dry, it will cause damage to the mechanical seal or cause pump failure.
Can self priming pumps be used in pits?
It isn’t uncommon for self-priming pumps to be used in pits that might have debris or other small solids. If something gets sucked up and clogs the piping or pump, you will experience poor flow. This isn’t as easy to diagnose as a crack or leak, but should be checked if you’re having priming problems.
What happens when a pool pump loses prime?
In this situation the pump is attempting to draw water faster than the pipe can provide water.
Why does my pool pump lose prime?
Pump loses prime from lack of water flow - One of the most common reasons that your pool pump might lose prime is simply that the strainer basket in either the pump or the skimmer is too full of leaves or organic debris.
Why does a skimmer need a second to drain?
Since pumps are so powerful and move so much water it takes only a second for the pump to drain the skimmer dry or at least create a vortex whirlpool that snakes to the water surface and allows the pump to take a draw of air.
How long is the suction pipe from a pool pump?
In effect the suction pipe from your pump to your pool might be 20' long , but plugging in your vacuum hose can make the total distance now 20' plus the length of vacuum hose itself. If you have a pump that is undersized or perhaps nearing the end of service the additional pull may be simply too much for it.
Why does my pool pump overheat?
Commonly pool pumps can overheat during the heat of the day which can cause the internal thermal disconnect to trip, can cause the electrical breaker to trip, or can cause increased resistance in the electrical connections which drop voltage and deliver lower voltages to the pump temporarily.
What happens when you take your finger off the end of a straw?
However the moment you take your finger off the end and lose the vacuum the water immediately drains from the straw. When a pump momentarily takes a pull of air, not water, this is like taking your finger off the end of the straw in that the pump will immediately lose prime.
Why does a pool pump catch on fire?
Temperature affects resistance and so a heat generating electrical connection will increase in resistance as it gets hotter, which in turn will cause it to heat up more , which will cause further increase in electrical resistance...this is how electrical fires happen. Pool pumps can catch on fire like this. Before the pump ever catches on fire it ...
What causes a well pump to lose prime?
Causes of loss of well pump prime include more than a bad foot valve. A leak anywhere in the water system from pump and pressure tank, through piping, down to the end of the pipe in the well (foot valve) that lets water out or air into the system can cause loss of pump prime and thus loss of water pressure.
What happens if you have no water pressure?
If you have no water pressure, absolutely no water in the building water supply piping, and no water in the water pump, we've lost prime and the one line or two line jet pump may be unable to bring water back from the well. Of course other problems can cause loss of water pressure, but if the problem is lost prime in the well pump, ...
Why do jet pumps need a cavity?
The spinning impeller inside of a typical jet pump requires a water-filled cavity in order to develop enough lift power to bring water up from the well. Loss of well prime means that the water inside an above-ground well pump has been lost along with water in the piping between the pump and the well. . The air-bound pump can no longer lift water ...
Where to disconnect well piping?
Disconnect the well piping at the pump just past the check valve, to the point where you can look into the vertical rise of standing well piping entering the pump area.
Can a submersible pump lose prime?
but what you need to know here is that a submersible well pump won't lose prime unless the water level in the well has dropped below the level of the pump itself. If that has happened, the problem is lack of water in the well, not a pump priming problem.
Can air leaks cause a loss of prime?
Air leaks here permit water to drain out of the well piping, losing prime. Air leaks at an above-ground jet pump, in the pump casing or impeller assembly can cause loss of well prime. Bad check valve at the well pump or bad intermediate check valves on deep wells using multiple check valves.
Can a jet pump run but no water is delivered?
But where a one line or two line jet pump is installed, you may have lost prime at the pump. The pump motor will run but no water is delivered. If this happens it is possible to re-prime the pump with water from another source. Watch out: before proceeding, turn off electrical power to the well pump.
How does a self priming pump work?
HOW A SELF PRIMING PUMP WORKS. A BRIEF NOTE OF CAUTION: Just because they’re able to pull fluid into them, doesn’t mean that they should start up dry!! Self-priming pumps need fluid in the casing to get started. Running dry, even for a short while, will cause damage to the mechanical seal, and pump failure.
What is self priming centrifugal pump?
Self-priming centrifugal pumps are unique. As the name suggests, they have the ability to prime themselves under suction lift conditions. They draw fluid up from tanks or pits below, making them easier and safer to work on than those that work below ground. Under the right conditions, they’ll free themselves of entrained gas ...
What happens when the recirculation port is plugged?
If the recirculation port becomes plugged, the eye of the impeller is unable to create an area of low pressure in which to pull liquid up the suction line.
How does air pressure affect an impeller?
Atmospheric pressure is higher than the lower pressure created at the eye of the impeller, thus fluid is forced up the suction line. As fluid moves up the suction line, the air ahead of the fluid is pushed into the casing and handled as the initial prime was handled through the recirculation process. Once the fluid arrives in the pump, it operates ...
What happens if an impeller is plugged with debris?
If the eye of then impeller is plugged with debris, it removes the hydraulic capability of the impeller to create an area of low pressure. 3. PUMP IS AIR BOUND. A pump can become air bound if it experiences any of these conditions:
What happens if a suction line leaks?
However, if there’s a leak in the suction line, air continues to be drawn into the pump, never allowing it to release enough to create that area of low pressure. 2.
What happens if there is no air release line?
If there is no air release line, air cannot be vented to the atmosphere, and instead collects on the discharge side. Valve on the air release line is closed, and the valve on the discharge line is closed, again, giving no place for the air to go and get out of the pump.
