5 benefits of using swimming pool pump cover

Ahh, the backyard swimming pool, is there anything more enjoyable than a dip in the cool, clear water on a hot summer day? If there is, then it might be lying by the poolside getting a tan after that refreshing swim. Having your own pool can be a great way to have fun, relax, and stay fit, but there are also a lot of things that have to be done to keep your pool looking, and feeling its best. One of these things is to make sure that your pool pump is in good shape and that means protecting it. Your pool pump is a powerful piece of delicate machinery that needs to be kept in a secure location where it can do its job without interference from family, pets, animals, the elements, and accidents. The best way to protect your pool pump is to use a pool pump cover. You can either buy a cover for your pool pump equipment, or you can build one yourself that will perfectly match your poolside area decor. Either way it’s vital that you use a cover to protect your pool pump equipment in order to get the most out of your pool now and for many years. Let’s look at some of the many benefits of using pool pump covers.

Protecting The Pool Pump from The Elements Such as Wind, Rain, Ice, and Snow

The weather can have a serious effect on the components of your pool pump and pool heater equipment. The pump and heater need to be protected from things such as heavy rain, strong winds, and especially snow and ice. Freezing of lines and internal components are one of the leading causes of pool pump damage. A cover will help provide an air dam around your pool pump and heater equipment to reduce the risk of freezing, and shield the equipment from potential damage from other weather conditions.

Protecting The Pool Pump from The Damage That Sun Exposure Can Do

The plastic and rubber components of your pool pump can be quickly damaged by exposure to direct sun. In fact, exposure to direct sunlight over just one summer can reduce the life of your pool pump equipment by as much as 15-20%. The use of a swimming pool pump cover can extend the life of the equipment and help you get more out of your 

Protecting The Pool Pump from Damage from Animals

Don’t let the hoses and wiring of your pool pump and heater get damaged due to small backyard animals such as gofers, squirrels, raccoons and more. The use of a full cover for your pool pump equipment can help prevent damage by keeping small critters out from around your equipment. Animal damage accounts for a significant amount of pool pump and heater repair costs every year in the U.S. This can be prevented by the use of a cover for the pool pump equipment. 

Providing A Small Storage Area for Other Maintenance Items

A cover enclosure for your pool pump and heater equipment can also provide you with a place to store other important equipment related to your pool such as your pool vac unit,skimmer, and more. Having a central place to keep all of these things, not your chemicals of course as those should be stored in a secure place indoors, is a great way to make keeping your pool clean and clear easy.

Creating A More Beautiful and Peaceful Poolside Area

In addition to protecting your swimming pool pump and heater equipment from damage, the use of a pool pump cover can also help make your poolside area more pleasant by hiding this large and bulky equipment out of sight and behind a beautiful cover. Covers for pool pumps and heaters come in a wide variety of styles and colors, or can be custom built to perfectly match your poolside area’s appearance. As an added bonus a cover for your pool pump and heater can also help to reduce the noise factor when the equipment is in use, therefore, making your poolside more peaceful and relaxing for you, your family, an your friends. Your neighbors might be happy to not have to hear your pump running all night either.

These are just a few of the many reasons why you should be using a pool pump cover. These covers can not only help make your pool last longer by protecting it, but can also help protect you and your family from potential injury from this powerful piece of machinery. A pool pump cover also helps to keep the unsightly mechanisms out of view, while simultaneously reducing noise when the pool pump is running, and therefore helps to provide of a more beautiful and peaceful environment around your pool. The use of a swimming pool pump cover, is a great way to make sure that your pool is at its best season after season, year after year.

6 Reasons Why Pool Pump Making Loud Humming Noise

One of the best ways to discover potential damage to your pool pump is by noticing excessive vibrations. These vibrations could be a result of embryonic faults, component failures or poor running conditions. This is why it is important to monitor the vibration levels of your pool pump regularly. Your pool pump’s dependability, safety, and production capability can be improved through regular monitoring. It is critical to understand the causes of the excessive vibrations and how to correct them. This post will focus on determining the root causes of pool pump vibrations.

Many conclude that vibrations are caused when the rotor of the pool pump is out of place.  But it may not be the imbalance of the rotor; there are many other causes.  There are ways to identify the source of the vibrations because each of them has specific frequency signatures. Let’s take a look at some of them:

1. Pump Bearing Problems

Bearings are placed onto the pool pump motor to help reduce the friction as the electromagnets make the motor shaft spin. But when the rolling element starts to wear, vibrations can be triggered. The number of bearing balls or rollers is what determines the frequency signature of the vibration.  This frequency is best determined by the manufacturer of the bearing part of a pool pump. An effective way to prevent the failure of the pump bearings is to lubricate the bearings with recommended oils regularly.

2. Bent Pump Shaft 

A bent shaft of a pool pump also causes high axial vibrations in the pump. If the bend is near the shaft center, notable vibrations may occur at 1X RPM. However, this is not as common as when the bend is at or near the coupling; it can occur at 1X RPM. Dial indicators are best used to identify a bent shaft in a pump.

3. Misalignment of the Shaft

Some vibrations are normal, but it sometimes takes a professional repair technician to determine the level and cause of excessive vibrations in a pool pump, especially if a shaft misalignment causes the excessive vibration. They can also tell how far it will affect the performance and reliability of the pool pump. It’s not too easy to detect a misalignment of the shaft; there’s hardly any sensor that can be placed on a pump to determine the level of force being used. However, you can generally diagnose a pool pump for shaft misalignment if you notice any or a combination of any of the following; excessive oil leaks at the bearing seals, heat of the discharge oil, excessive coupling failures, breaking or cracking of shafts, high temperatures near the casing or bearings, excessive axial or radial vibrations, and loose coupling, among others.

4. Imbalance of the Pump Impeller

You cannot avoid episodes of vibrations if the impeller of your pool pump is imbalanced. An imbalance of the impeller makes your pool pump seem misaligned, overheated, to have a bad bearing. Ultimately, you begin to sense some vibrations too when this occurs. Apart from these problems caused by an imbalanced impeller, this condition can also be dangerous in one or more of the following ways; seizing of the pool pump, failure of the mechanical packing, shaft deflection, etc. A centralized pool pump impeller causes more of a force imbalance than couple imbalance. In this case, we are looking at radial directional vibration with amplitude speed of about 1X RPM.

5. Cavitation

When the net positive suction head is insufficient, pump cavitation sets in. Usually, the absolute pressure of the liquid at the impeller shouldn’t approach the liquid vapor pressure in a swimming pool pump. This is what prevents pockets from forming and collapse as they pass through the impeller. But when the contrast happens, cavitation occurs, thereby causing vibrations in a pumping system. In simpler terms, cavitation happens when water is lower than the recommended amount within a time frame. In other words, the pump is starved of water while the impeller spins. This can cause a loud clattering sound, and in turn, excessive vibrations. The sound of a pool pump vibration caused by cavitation can be identified by a seeming rumbling rock sound or distinctive popping.  Beyond the vibrations caused, more energy is expended by the pump, and potential damage is set to occur if you do not quickly take care of cavitation.

6. Pump Flow Pulsation

It’s a really not too good for a pump to be operating near its shut-off head. This occurs when the pump runs with the discharged valve closed. If this happens for too long, pump flow pulsation occurs thereby leading to vibration of the pump. Of all the major causes of pulsation, the lack of proper feed is a major one. Other causes of pulsation could include leaking valves, worn packing, improper spring rates, piping designs that restrict flow, and multiple pumps on a common header. A suction stabilizer to keep the contact of the fluid with the plunger is one of the best ways to prevent pulsation.

What are the different types of swimming pool pump noise?

Certain pool pumps based on their make, produce a loud noise. While other swimming pool pumps that are manufactured by companies (mostly R&D based) are created or designed to be quieter.

The main source of pool noises is the pool pump which is the heart of the swimming pool working system. The pool pump can make differing sounds and just in case you have been curious about what the noises your pool make are called, this post reveals some of the most common types.

The first step to diagnosing a noisy pool is to observe the sort of noises it produces. Here are descriptions of the common noises.


The rattle sound is a rapid series of short, sharp, loud sounds, like the type resulting from the collision of hard objects such as clanging metal. This noise can be an indication that there are loose screws and that your swimming pool pump isn’t seated properly on its base.


The clattering noise can sometimes be compared to the sound of marbles moving around the pool pump. This sort of noise caused most times by cavitation. We would go through this occurrence in a bit.

Rumbling or screeching:

Rumbling is a low continuous heavy deep, resonant sound, or a series of sounds such as the sound made by heavy vehicles or thunder. Screeching, on the other hand, is a sharp, high-pitched sound like that of car tires when the break is pressed suddenly. These noises mainly signal that the bearings of the pool pump motor are wearing out, which is a familiar issue.

Bearings are placed on the motor to help reduce the friction as the electromagnets make the motor shaft spin, and therefore wear out easily. Any frequently used swimming pool pump will need to have bearings change eventually.

5 best practices you should try to reduce loud pool pump noise

During the normal operation of a swimming pool, there’s bound to be some sort of noise by pool pump. This noise isn’t excessively annoying, but when it becomes louder, it means there’s a problem with the pump that should be checked out. If it is not addressed in time, the issues will get worse and the pool pump motor will become unusable. There are different reasons that may cause a pool pump to fail, from cavitation, internal blockage, worn-out bearings among others. The noise can range from screeching to rumbling and clattering. Here are a few tricks to quiet your pool pump devices.

    • Adjust the base of your swimming pool pump:

      If your pump is vibrating excessively, it’s a sign that your pool pump motor is out of place. To fix or prevent this kind of movement and noise, tighten screws to secure and hold down your pool pump. You can also place an absorbent pad beneath the pool pump motor. To do this, you should first remove the bolts holding the pump to the concrete pad, place a piece of carpet or rubber pad beneath the motor and screw the pool pump motor back in place.
    • Check and Clean skimmer baskets:

      Debris or floating objects can get stuck in the skimmer basket and lead to eventual clogging. This, in turn, will cause the water pump to run dry. This can cause your pool pump to heat up and maybe fail. In this case, check your skimmer baskets to ensure that there’s no blockage. If there is, clean it out so that water can flow easily to the pump motor and the right rate.
    • Raise water levels:

      It is possible that the pool pump noise persists even after cleaning the skimmer baskets. In this case, it may be that the water level in the pool is not high enough to flow into the pump. Adjust the water level, and the noise will reduce drastically.
  • Clean Impeller:

    Turn off the pool pump motor and disconnect from the power source. Then take off the clear cover from the pump body, remove the strainer basket so you can see the impeller. Make a hook out of a coat hanger and insert it into the impeller opening on the pool pump motor located inside the area that held the strainer basket. Use the wire hook to fish out any debris inside the impeller. After cleaning it, replace the skimmer basket and lid of the pool pump. Turn on power to the pool pump motor.

Changing of Bearings:

Bearings are placed on the pump to help reduce the friction in the spinning motor shaft and they can easily wear and tear than other components of the pool circulation system. Also, motor bearings cannot be greased. The options are to either change them or to replace the pool pump motor completely. On the brighter side though, the cost of replacement is relatively low, although the extensive effort is required.
