How To Improve Your Pool’s Circulation

Keeping the pool’s water clarity can be easy once you understand the science behind it. Proper water chemistry is vital to keeping the water from getting cloudy and preventing algae from growing. But maintaining the chemical levels in balance is not enough. The pool can still run into issues if the water doesn’t circulate properly. To learn how to remedy the problem of poor water circulation, read the following lines and apply the advice given here.

The Importance of This Process

As a pool owner, you probably feel overwhelmed by the maintenance work that is required for you to do. Nonetheless, you still have to go through all the steps in order to ensure that it is actually safe for you and your loved ones to swim in the pool. While you are definitely aware of the fact that the pool’s water has to be cleaned regularly and that you have to add certain chemicals to it to ensure that bacteria don’t thrive in this environment, you might not be as aware of the importance of poor circulation. Know that this is actually the first step in the process of maintaining the pool clean and safe to use due to the fact that it allows water filtration and it helps with spreading chemicals in the water. Therefore, you cannot avoid it if you want to keep the pool in a top-notch shape. The process of circulating the pool’s water is performed by the pump of the pool which has the role of sucking in the water from the pool and passing it through the filter. Once it arrives in this area, it is cleaned of all impurities, after which it is pushed back into the pool through a jet. All in all, this is a process that you definitely cannot skip on, and one that doesn’t require any real effort on your part either.

Determine the Pool Turnover Rate

Have you ever heard about the turnover rate of a swimming pool? If not, it is necessary to understand the meaning of this term. The turnover rate is the number of times a pool’s water can be filtrated through the filter system. It is not important to know this number for your swimming pool. However, if you are planning to determine it, you can run the pump and filter 8 to 10 hours a day. In order to maintain your pool’s water clean and clear, circulation is very important. However, it is very easy to do it, since the pump is doing all the work for you. Aside from running the pump and filter 8 to 10 hours a day, you must keep the pump baskets and skimmer clear of debris and angle the return jets to spin the water in a circular motion. Plus, you have to brush the pool once a week and hit all the dead areas.

Position the Jets

All pools have 2 or 3 return jets where the water that filters through the circulation system returns to the pool. To improve your pool’s circulation, you should use multidirectional jets. Due to the fact that they allow you to determine the direction that the water returns to the pool, they make it easier for you to improve the pool’s circulation. Point the jets in a direction to spin the water in the pool. You should direct the jest to emit water downward, in the opposite direction of the pool skimmer. This setup will help mix the water from the bottom of the pool with the water at the surface, leading to improved circulation.

Take Care of Dead Areas

No matter how well you set up the jets, there remain areas in the pool that suffer from poor circulation. These areas are also known as dead areas. The dead areas include the areas behind the pool steps and ladders, the corners of rectangular pools, the center of round and oval pools, the bottom half of pools that don’t have a main drain and the areas adjacent to the skimmer and the return fittings. The best thing to do is to replace your standard return jets with specialty fittings that are designed to circulate the water by rotating. Also, you can run the pool filter at least 8 hours per day for the water to move through the circulation system regularly. Another way in which you can improve circulation is to use the pool for swimming and play activities regularly.

Clean the Pool on a Regular Basis

Another important step in improving the pool’s circulation is to clean the pool on a regular basis. Make sure that you brush the dead areas to remove algae, dirt, and other debris that might cling to these areas. This will give the filter a chance to remove them from the water. Make it a habit out of brushing the pool at least once per week with a brush that is fitted to a telescopic pole to easily reach all the areas of the pool. Also, you should vacuum the pool regularly to improve circulation. Hook up a robotic pool cleaner and let it on the bottom of the pool at least once per week to clean and take care of the dead areas. This type of cleaner will do the job for you. Therefore, you can lay back and let it work on cleaning your pool.

Clean the Filter

Last but not least, you must clean the filter regularly to prevent clogs that might back up the system. If you have a cartridge filter, turn off the pump and open the air bleed valves for the water to drain from the filter housing. Remove the cartridges and rinse them thoroughly. Afterward, clean the filter tank of debris as well. If you have a sand or diatomaceous earth filter, turn the pump off and open the valve for the waste or discharge line. Next, attach the discharge hose and direct it where you want the dirty water to go. Move the filter lever to the backwash position and restart the pump. When the water in the filter’s view glass is clear, turn off the pump, set the lever back to filter, and restart the pump.

Reasons Why It Doesn’t Work

When this system doesn’t work, you will notice that the water will become dirty or cloudy. But why exactly does the pool circulation system stop working properly? There are a few reasons behind this malfunction, and it’s important for you to know them in order to fix the system or prevent this from happening. In case the pool valves don’t have the correct settings, the circulation system won’t work. Therefore, make sure that all the valves are either opened or closed to help the water filter through the system. Another reason for this occurrence might be a clogged pool filter that needs to be changed or repaired. Also, if the airlock system is leaky or closed, the air valve system will fail to function, thus causing a weak performance of the circulation system.

Frequently Asked Questions

1 How can I determine my pool’s turnover rate?
The turnover rate is the amount of time it will take to circulate all the water in your pool through the filter system.

2 Can I clean the water without chemicals? How is this possible?
To clean the water without chemical, you must use biological filters.

3 Do the biological filters need to be cleaned out?
Since the filter tubing is covered with at least 9″ of expanded shale, the debris cannot get down to clog the filters.

4 How often should I clean my swimming pool?
It depends on how dirty and cloudy the water is. According to several specialists, it is recommended to clean it at least once a week. Clean it twice a week and everything will be fine.

With this product at your disposal, you will have a spotless pool without putting any effort into keeping it clean.

  2. Emma says:

    How should I test the swimming pool water chlorine and pH level?

    • Becky Eddinson says:

      One of the most efficient and easiest ways to test for pH and chlorine is to use 3-Way Test Strips. The color pads on the strips are quick indicators for pH chlorine and alkalinity.

  3. Mick says:

    Hello! Should I clean my swimming pool more than twice per month?

    • Becky Eddinson says:

      Hello, Mick! It’s recommended to clean your pool once per week. Whether you use a robotic pool cleaner or a brush that is fitted to a telescopic pole to easily reach all the areas of the pool, you need to take care of your pool at least once per week.

  4. Noah says:

    How often should I clean my pool filters?

    • Becky Eddinson says:

      It depends from filter to filter. However, as a general rule, it’s recommended to take a reading when the filter is clean or clean it when when the pressure rises about 10 psi.
