Why won’t my pool filter spew out water?

A private pool clean is a decoration of the site, a place where the family enjoys spending time.

The basis of water purification systems in swimming pools are pressure filters. The quality of water in the pool mainly depends on their proper selection and operation.

But it happens that your pool filter is having difficulty working or not working at all, and you need to know why this is happening. In this article, we will look at common problems and their solutions.

General concepts of water filtration

Filtration is the process of passing purified water through a layer of filter material. Filtration is used to clarify water, that is, to retain suspended solids in the water. The filter material must be a porous medium with very small pores.

In the technology of water treatment of pools, quartz sand with a particle size of 0.4–0.8 mm is used as the main filtering material. In plumbing practice, filters with such a grain size of the load are called medium-grained.

Reasons to use a pool filter

Water purity is not only aesthetics. If you do not follow it, in a matter of days, mucus appears on the walls of the pool, the water becomes cloudy, and there it is not far from flowering. The reason is that stagnant water is an excellent breeding ground for microbes and algae, and if not kept clean, pool water can cause not the most pleasant diseases of the gastrointestinal tract.

Therefore, it is desirable to keep the pool clean. In most cases, the owners do not have the opportunity to change the water every three days

The best option is to install a filter device. His choice should be taken very carefully, since it will be responsible for several processes:

• Purification of water from small debris: grass, insects, sand.
• Support for water circulation, which prevents the flowering of the water surface. Thanks to this feature, you can save on disinfectants.
• Helps distribute disinfectants evenly throughout the volume of water.

All these tasks will be solved if you choose a pool filter with suitable characteristics, and the choice depends not only on the volume of the pool, but also on the filtration method used.

How do you know if your pool pump is about to stop working?

A good pool pump has a lifespan of almost 8-10 years with proper maintenance. But how to understand that the pump will soon fail?

The pool pump often leaks

If you have repaired the pump leaks and they still occur intermittently, then the seal on the motor shaft is most likely worn. It can be replaced quite cheaply and avoid buying a new pool pump.

But if even after replacing the O-ring, water still flows from the pool pump, even when it is turned off, this is a sign that the oil seal on the motor shaft has worn out.

You have a low PSI from your filter

If the pressure gauge on your filter is below normal, then you have a clogged skimmer basket or pump screen. But if this continues to happen even when the skimmer basket is empty, the impeller may soon fail.

The pool pump is losing prime

Even if you have correctly corrected the problems, you may still have problems keeping your pump in working order. It could be warped parts or it could just be time to buy a new pump.

What is a pool pump made of?

Pump Lid:

The pump lid is where you can easily check the operation of the entire filtration system. If you find air bubbles or lack of water while the pump is running, it could be an air leak on the suction side of your pool or in the lid o-ring. These air bubbles push the water out of the pump and filter, which stops the flow.

The suction side (in front of the pump) should pull from the skimmer.

Filter housing with basket:

Water from the spring first enters here and collects debris before it reaches the transmission.

Drain plug:

Needed to drain the pump before winter. There may be several on the pump.

Pump housing with impeller:

Pump housing is the most important part, here is the impeller, diffuser and seals. The impeller rotates on the motor shaft, which pumps water from the pool to the filter.

Motor and shaft of pool pump:

It is needed in order to rotate the impeller.

The most common pool pump malfunctions

It is important for swimming pools to be in a safe and clean condition. And if your pool pump isn’t pumping water, your pool water will turn into a swamp.

It is very important to resolve this issue as soon as possible.

Why is your pool pump not pumping water? Here are some common reasons:

• The dirty pool filter;
• Air in the plumbing;
• Stuck Check Valve;
• clogged plumbing;
• Garbage in pump basket;
• Pump basket not primed;
• Broken impeller;
• Incorrect valve orientation;
• Faulty pump motor.

Why is my swimming pool pump not pumping water? Top 5 pool pump problems

A pool pump is one of the most important parts of your pool’s plumbing system. It is responsible for creating pressure in your pool, which causes water to flow through the filter. Think of it as the heart of your pool – without a filter and pump, your sparkling pool will quickly turn into a muddy pond.

Unfortunately, there are cases when your pool pump won’t work, and there can be many reasons. In this article, we will look at the most common pool pump problems.

The pump does not draw water

If your pump is not moving water, you should first check the skimmer and pump baskets to make sure they are empty and not restricting water flow. Next, make sure your pool filter is clean – a dirty filter can also block flow. After you have checked this,

you can check the pump impeller. This is the part of the pump that is connected to the motor and is responsible for the movement of the water. Impellers will clog from time to time, especially in spring. To inspect the impeller, open the pump to see inside the impeller housing or volute.

One of the main causes of loss of suction in a water filtration pump is an air leak in the suction line that supplies the pump with pool water. You may know this is a problem if your pump fails to catch a charge, i.e. when your pump is running at full capacity. The pump is designed to suck water,

but it can and will suck in air if possible. Air has less mass than water, so the pump will suck in air before it can suck in water. If you think you have an air leak, go to step 5.

Water flows out of the pump

The reasons for water leakage can be due to a bad impeller housing O-ring, a bad shaft seal, as well as a bad thread sealant or shrinkage threads on the drain pipe .. If it is an O-ring or seal, then you can order seals for your pump.

The motor will not run or will turn off after a while

There are many things that can cause this problem. If you want to start by checking engine power. Check your switch and make sure your timer is set to turn on the pump. If you are getting energy, the next thing to check is the sounds.

Do you hear the hum of the motor or hear a click? A humming motor could mean a bad capacitor. Think of the capacitor as the one that starts the motor and starts spinning. The capacitor stores a quick charge of electricity to start the engine. They can be located at the rear of the engine housing, as well as on top or on the side of the device.

If your engine is running but shuts off after a while, it could be causing it to overheat. Pool pumps consume a lot of energy and need a constant supply. If it’s the middle of a hot day and everyone in your area has high AC levels, it’s possible that the drop in power will cause the motor to overheat.

There isn’t much you can do at this point, except maybe run your pump at night when it’s cooler. The second main reason for this is a malfunctioning engine fan or ventilation blockage. There are vents on the underside of the engine that can become clogged with dirt and leaves. Make sure that you do not have dirt and keep them open and clean.

The motor/pump makes a loud noise

Everyone dislikes a loud pool pump. If your pump is loud, the first thing to do is listen to it.

What sound does it make? If it sounds like it has rocks in it, it might be because it’s vibrating on the cushion it’s sitting on a piece of rubber mat underneath can help stop the noise.

If it doesn’t, it could be cavitation. Cavitation occurs when the pump cannot get enough water fast enough, or the pump “starves”. The pump impeller spins too fast with not enough water and starts knocking air molecules out of the water.

If you just installed an oversized pump, you need to check the lines for clogging or a closed valve. In some cases, this may be a clogged filter or impeller. Remove all obstacles and everything will be fine.

Now, if your pump is screaming, your motor may need new bearings.

The bearings are mounted on the motor shaft of the pool, inside the motor, to reduce friction as the electromagnets make the motor shaft rotate. This is high wear in the engine. . Most motors have two different sizes of bearings, and removing them usually requires a special bearing removal tool.

The motor/pump sucks in air

Pool water pumps must be sealed. There must be no air in the basket under the transparent cover of the pump. However, this is rare, as small air leaks are common. If the air leakage becomes too large, this can create circulation problems or pump delays.

The most common causes of pump air leakage include poor thread sealant. Other sources of air entering the system include a leaky or old pump cover, a bad pump cover O-ring, or a badly installed pump drain plug.

How to Understand Pool Filter Pressure Problems?

Your pool pump filters the smallest particles of debris from the water, making it clear. But none of this will work without water pressure. The pressure allows the water to pass through the filter. To monitor the pressure on each filter you will find a pressure gauge.

You need to know how a filter pressure gauge works and how to use it to solve pool filter pressure problems.

The pressure gauge is the part of your filter that tells you what’s going on and when you need to inspect the filter. Most gauges range from 0 to 60 psi. The small arrow indicates your filter pressure in PSI (pounds per square inch).

Each filter has its own pressure ratings. The rate is approximately 10 to 20 pounds per square inch. To find good pressure for your filter, you just need to test it. Clean and rinse the filter, then you need to fill it a little. Don’t forget to write down the PSI when the pressure stabilizes. This will be your ideal PSI.

Make a note with your pressure indicator near the pressure gauge, it is important for you not to forget it in the future.

Cause 1: The filter pressure is too high

When the filter becomes clogged, the pressure in it can rise. There are other problems that can cause a pressure surge. As long as the PSI is no more than 10 PSI above ideal, you don’t need to do anything. But when the PSI goes up by 10 or more psi, then you need to think about cleaning the filter.

If the pressure returns to normal after washing the filter, then everything is fine.

If the pressure gauge continues to show a high value, then inspect the filter again, something is not working properly. Something is preventing the water from flowing back into the pool after it has passed through the pump.

• Check valves are closed, partially closed or broken.
• What-something is wrong with your filter material (cartridge, sponge or sand.
• Broken filter parts.
• Lime deposits in the pool heater blocking the flow of water

If there is a problem causing high pressure, turn off the pump immediately. High pressure surges can ignite the filter, resulting in serious injury or even death.

Cause 2: The filter pressure is too low

Too much air reduces the pressure and prevents the pump from pulling water.

Low pressure is not as dangerous as high pressure. However, this means that your filter is not working correctly. Low pressure is often caused by a problem in or upstream of the pump. This is because after the pump, the water is under pressure, so any problems will create high pressure, not low.

Low pressure is caused by an obstruction or other problem preventing water from entering the pump.

• Skimmer or pump basket clogged;
• The impeller of the pump is clogged;
• The filter valve drives water around the filter;
• The skimmer or main drain valves are closed or partially closed;
• Skimmer or main drain pipes clogged or destroyed;
• Air enters the system at the pump inlet, pump head or valves.

If you find an obvious blockage in the skimmer, you just need to clean it out. If the problem is in a closed valve, open the valve to normalize the pressure. But if there is a blockage inside the pipes or you see that the pipes have collapsed, you would be better off calling a pool specialist.

Reason 3: The pool filter sensor is broken

It happens that you get perfect readings, but you still understand that there is a problem. Your task is to check the pressure in the filter weekly. If your filter pressure doesn’t change for a while, your pressure gauge is most likely broken.

If the pressure gauge points to zero when the pump is running, then this is not a difficult problem. Air unit under the pressure gauge, which measures pressure could just be clogged. Unscrew the sensor, clean it and replace it. If the sensor returns to reading something in the normal range, you have found the problem. If the sensor still does not move, it may be broken.

Now you might need a new pressure gauge. A good pressure gauge will cost you less than $20. When replacing the pressure gauge, be sure to use Teflon tape on the threads for a snug fit before screwing it into place.
