Pump losing prime from low water level - A very common reason for a pool pump to lose prime is from the water level in the pool being too low, or possibly the weir in front of the skimmer mouth getting stuck in the up position… The moment that the pump is able to draw air it will lose prime.

Those who are looking for an answer to the question «Why does my pool pump keep losing its prime?» often ask the following questions:

❓ Inground pool losing prime when vacuuming?

If there's a hole near the top of the hose and it's near the surface it's going to suck in air that's going to cause you to lose prime… That's a very common spot for air to get in especially when you connect the vacuum hose and increases that pressure, it could pull in air and cause the pump to lose its prime.

❓ Why does a pool pump lose prime?

  • Small air leaks reduce the efficiency of a swimming pool pump and cause an irritating gurgle in a swimming pool, usually at the return jet closest to the equipment. Large amounts of air can bring the system to a complete halt by causing it to lose prime.

Pool losing water when pump is running?

Generally, if you're losing water when your pump is running, you have a pressure-side return leak. When you're running your pump, the plumbing after the pump is under pressure. Often times, this can lead to small leaks and water sprays through your line (from the filter to your return jets.)

Why is my pool pump losing suction?

If the impeller becomes clogged with debris, water can't rotate out the sides of the impeller. This decreases suction which reduces water flow through the pump. Solution: Clean out the impeller.

Do you have to prime pool pump?

Many pool pumps nowadays are self-priming, meaning that they can automatically generate water flow after turning on, even if there are significant amounts of air in the system. Some pumps require you to manually prime your pump before turning it on… 6) Use a garden hose to fill the pump basket up with water.

How do i prime my pool pump?
  • How To Prime A Pool Pump In 7 Easy Steps Step 1. Turn off the pump Step 2. Switch the multi-port valve to recirculate Step 3. Remove excess air Step 4. Clean out the pump basket Step 5. Fill the pump basket Step 6. Turn on the pump Step 7. Close the air valve
How do you prime a pool pump?

I have a pump that has a catch basin where leaves and other debris is collected. Two screws hold the top onto the catch basin. When I remove the basket inside, there is water in there along with the basket. With your pump OFF, remove the top to the catch basin. Empty an debris in the basket. Fill a bucket with water and pour the water into this catch basin. (Note that you will only be able to fill it so far, and the rest will go into your pool. As long as you have some water (6-8 inches) in the catch basin, you won't have to worry about running the pump in a dry state.) Replace the basket and the top to the catch basin and screw the top on snugly. Make sure your filter handle is in the position to circulate the water. Turn on the pump. If these instructions do not work, turn off the pump immediately and consult a pool supply company, or a pool repair company for advice. : I agree with the above comment. To improve on it: If you have a valve in front of the pump, close it before opening up the pump. Fill the pump housing up comletely with a water hose/bucket. Open and close the valve as many times as needed until you no longer get the "burping" action. Make sure the water level stays full while you're doing it. This will help get any air out of the lines, so that the pump primes more quickly once you turn the pump back on. P.S. Don't forget the re-open the valve. If pump still does not prime, you may have a leak in the plumbing. Check the nipples going in and out of the pump first to make sure they are not sucking air in. Check any valve bodies for same. Seal any leaks and repair/replace as soon as possible. I can answer any pool-related questions at anjeli-klean.com

How to prime a index pool pump?

Why will a pool pump not prime?
  • There are several reasons why pool pumps tend to lose their prime or are unable to reprime themselves, the most common problem results from air in the pipes or filter. This is usually caused by the pools water level being too low or sometimes is caused by loose fittings or perished o'rings.

Why does my hayward pool pump keep leaking?
  • Leaks can also come from loose drain plugs or loose on bolts on the seal plate, connecting the motor to the pump. If the water is running down between the pump and motor, determine if it’s dripping out of the plumbing fitting on top or the shaft seal on the bottom.
Why does my pool pump capacitor keep failing?
  • Another reason for the failures, the capacitor is faulty from the start, either it is from a bad batch or mishandled before it installed. But if you’re having this problem repeatedly, it’s probably not the capacitor. It’s probably the fact that you just have an old motor.
Why does my pool pump impeller keep cracking?
  • The spinning action of the impeller when driven by the pump motor generates the water pressure in your pool system. Sometimes debris will get into the pump and will crack the impeller. In other cases the threads that hold the impeller to the motor shaft become worn causing the impeller to wobble and rub against the diffuser.
Why does my pool pump keep blowing bubbles?
  • Most filters will self-bleed the air out through the return jets by blowing bubbles. If air is accumulating in the filter and possibly draining the pump out when you switch it off your pump will be sucking air but you may not have enough back pressure to bleed the air.
Why does my pool pump keep leaking water?
  • There is a constant flow of water to the skimmer / pump. I'm wondering if I have an air leak in my pump somewhere. When I turn the pump off water leaks from around the pump skimmer housing. I changed all of the seals a few weeks ago, and the skimmer lid is secure.
Why does my pool pump keep running dry?
  • If the pump has no water to pull from the skimmer, it will draw air instead and lose prime which leads to running dry. At the least, this will ruin the motor shaft seal which is what prevents water from getting inside the motor. If it keeps running dry, the pump heats up and so does the water inside. Commence melting plastic.
Why does my pool pump keep shutting off?

The pump is a vital component to your swimming pool… There are several reasons why your pump may randomly shut off—a behavior known as "pump tripping." Most commonly, your pump may be operating at the wrong voltage, overheating, or simply failing to compete with your neighborhood's electrical needs.

Why does my pool pump keep slowing down?
  • Pressure keeps slowing down out of return jet. Pool return line could be partially blocked meaning that there is a wall of water building up in the system reducing the pressure. Have the same problem and currently trying to cut out the section of blocked pipe. Like you we replaced sand in filter, New pump etc.
How long does it take a pool pump to prime?

Allow water to run into the pump housing for at least two minutes. This will allow some water to seep into the pipes that extend from the skimmer to the pump so there'll be enough water to create suction in the pump.

Do i need to prime my pool pump?

A pool pump must be primed, to work properly. Priming is what supplies the pump with enough water to put the water in circulation or, in other words, to start pulling water from the pool. Self-priming pool pumps automatically generate the flow of water, even if there is a lot of air in the system.
