FAQs

Swimming pools can be hygienic if they are properly maintained and disinfected. Proper maintenance includes regular testing and adjusting of the water chemistry, such as pH, chlorine, and alkalinity levels, and cleaning the pool, such as skimming the surface and vacuuming the bottom. Additionally, it is important to keep the pool area clean and free of debris, such as leaves and grass clippings, to minimize the number of contaminants that enter the pool.

Proper disinfection is necessary to kill harmful microorganisms that can be present in the water, such as bacteria and viruses. The most common method of disinfection is through the use of chlorine, which can be added to the water in the form of liquid, granules, or tablets. The chlorine level should be maintained between 1 and 3 parts per million (ppm) to ensure that the water is safe to swim in.

However, if a pool is not properly maintained and disinfected, it can become a breeding ground for bacteria and other microorganisms, which can cause health issues. It is important for pool operators to ensure that the pool is properly maintained and disinfected to minimize the presence of harmful microorganisms in the water.

It is also important for swimmers to practice good hygiene, such as showering before swimming, avoiding swimming when sick, and avoiding swallowing pool water, to minimize the risk of getting an infection.

 

Yes, it is possible to get bacteria from a swimming pool. Bacteria can enter a pool from a variety of sources, such as swimmers’ skin, hair, and clothing, as well as from the environment. Some of the most common types of bacteria found in pools include E. coli, Pseudomonas, and Legionella.

Properly maintained and disinfected pools should have low levels of bacteria. However, if the pool is not properly maintained or disinfected, the levels of bacteria can increase and potentially cause health issues.

To minimize the risk of getting bacteria from a pool, it is important to practice good hygiene, such as showering before swimming, avoiding swimming when sick, and avoiding swallowing pool water. Additionally, pool operators should ensure that the pool is properly maintained and disinfected to minimize the presence of bacteria in the water.

 

The lifespan of a pool can vary depending on a number of factors, including the materials used to construct it, the level of maintenance it receives, and the climate it is located in. On average, the lifespan of a concrete pool is around 20-25 years, while the lifespan of a vinyl liner pool is around 10-15 years. Fiberglass pools have a longer lifespan, around 25-30 years. However, with regular maintenance and proper upkeep, a pool can last for many years beyond these estimates.

 

Balancing pool water involves adjusting the levels of various chemicals to ensure that the water is safe and comfortable for swimming. The following is a general guideline for how to balance pool water:

1. Test the water: Use a pool test kit to measure the levels of chlorine, pH, total alkalinity, and calcium hardness. Follow the manufacturer’s instructions for the test kit.
2. Adjust the pH level: The pH level should be between 7.2 and 7.8. If the pH level is too low, add a pH increaser (such as sodium carbonate) to the water. If the pH level is too high, add a pH decreaser (such as sodium bisulfate or muriatic acid) to the water.
3. Adjust the total alkalinity: The total alkalinity should be between 80 and 120 parts per million (ppm). If the total alkalinity is too low, add an alkalinity increaser (such as sodium bicarbonate) to the water. If the total alkalinity is too high, add a pH decreaser (such as sodium bisulfate or muriatic acid) to the water.
4. Adjust the chlorine level: The chlorine level should be between 1 and 3 parts per million (ppm). If the chlorine level is too low, add chlorine to the water. If the chlorine level is too high, add a chlorine neutralizer (such as sodium thiosulfate) to the water.
5. Adjust the Calcium hardness: The calcium hardness level should be between 200 and 400 parts per million (ppm). If the calcium level is too low, add a calcium hardness increaser to the water. If the calcium level is too high, add calcium hardness decreaser to the water.
6. Check the Cyanuric acid (if using stabilized chlorine): It should be maintained between 30 to 50 ppm to prevent chlorine loss due to sunlight.

It is important to wait at least 4 hours after adding chemicals to test the water again to ensure that the levels are in the appropriate range. It is also important to follow the manufacturer’s instructions for any chemicals used in the pool and to use test kits that are specifically designed for swimming pools.  

It is recommended to test the pool water at least once a week, or more frequently if the pool is heavily used or if there are sudden changes in weather or water conditions. Testing the pool water regularly will allow you to detect any problems early and make any necessary adjustments to the water chemistry. The following parameters should be checked regularly:

1. Chlorine: The chlorine level should be maintained between 1 and 3 parts per million (ppm) to ensure that the water is safe to swim in.
2. pH: The pH level should be maintained between 7.2 and 7.8 to ensure that the chlorine is working efficiently.
3. Alkalinity: The total alkalinity should be maintained between 80 and 120 parts per million (ppm) to help stabilize the pH level.
4. Calcium Hardness: The calcium hardness level should be maintained between 200 and 400 ppm to prevent damage to the pool surfaces.
5. Cyanuric acid (if using stabilized chlorine): It should be maintained between 30 and 50 ppm to prevent chlorine loss due to sunlight.

It is important to test the water and adjust the levels of the chemicals as needed, to maintain a balance and avoid any damage to the pool, equipment, or swimmers. Additionally, it is important to follow the manufacturer’s instructions for any chemicals used in the pool and to use test kits that are specifically designed for swimming pools.  

Emptying a swimming pool also called draining, is generally safe if it is done properly and with the appropriate precautions. However, there are several factors that need to be considered before doing so. Some of the key factors that need to be considered before emptying a swimming pool are:

1. Local Codes and Regulations: Check with your local municipality to ensure that pool draining is allowed in your area and if there are any permits required.
2. Pool Structure: Make sure that the pool structure is in good condition before draining. A pool that is in poor condition can be severely damaged by draining.
3. Water Table and Flooding: If the pool is located in an area with a high water table or potential for flooding, draining the pool can cause damage to the surrounding area.
4. Drainage: Make sure that proper drainage is in place to handle the large amount of water that will be released when the pool is drained.
5. Equipment: Make sure that the pool’s pump, filter, and heater are turned off before draining.
6. Gradual Draining: Drain the pool slowly and gradually to avoid any structural damage. Draining the pool too quickly can cause the pool shell or liner to collapse or crack.
7. Safety measures: Empty the pool with enough safety measures, if you are not comfortable with the process or have any doubts, it’s best to hire a professional pool technician to handle the job.

By considering these factors, you can ensure that emptying your pool is done safely and without causing any damage to your property or the surrounding area. However, if you are not comfortable with the process or have any doubts, it’s best to hire a professional pool technician to handle the job.  

If a pool is too full, it can put added stress on the pool structure and the surrounding area. A pool that is overfilled can cause the water to spill over the sides, potentially causing damage to the pool deck and surrounding landscaping. Additionally, an overfilled pool can also put added pressure on the pool’s plumbing and filtration system, which can cause leaks or other issues.

The overfilled pool also can cause problems in the pool’s skimmer and return lines, which can lead to poor water circulation and an increased risk of algae growth. Furthermore, the increased water weight can cause a structural failure in the pool or the surrounding deck, which can be dangerous and costly to repair.

It is important to regularly check the pool’s water level and adjust as necessary to ensure that the pool is not overfilled. A pool’s water level should be kept at the appropriate level, usually around halfway up the skimmer or tile line.

 

The frequency of cleaning a pool filter depends on the type of filter and the usage of the pool.

A sand filter should be backwashed every 2-3 weeks or when the pressure gauge indicates that the filter is dirty. The sand should be replaced every 5-7 years.

A DE (diatomaceous earth) filter should be taken apart and cleaned every 3-6 months, and the grid should be inspected and replaced if necessary.

A cartridge filter should be cleaned every 1-3 months or when the pressure gauge indicates that the filter is dirty. The cartridges should be replaced every 1-2 years or when they become too dirty to clean.

A pool with heavy use or a lot of debris will require more frequent cleaning than one that is used less or has less debris. Additionally, the weather and the environment can also affect the filter, for example, after a heavy storm or heavy leaves fall, the filter may need to be cleaned more frequently.

It’s important to follow the manufacturer’s instructions for your specific filter and to check the pressure gauge regularly to ensure that the filter is working efficiently. A dirty filter can cause the pool pump to work harder, which can lead to increased energy costs and can also cause damage to the pump.

 

Shocking a pool, also known as super chlorination, is the process of adding a large dose of chlorine to the pool to kill any bacteria or algae that may be present in the water. The frequency of shocking a pool can vary depending on a number of factors, such as the number of swimmers using the pool, the weather conditions, and the overall water quality.

It is recommended to shock the pool at least once a week, or more frequently if the pool is heavily used, or if there are sudden changes in weather or water conditions. Additionally, it is a good idea to shock the pool after heavy rain, if there has been a high level of bathers or if you notice a change in the water clarity or smell.

It’s important to follow the manufacturer’s instructions for the type of shock treatment you are using and to test the water after a shock to ensure that the chlorine level is safe for swimming, usually between 1-3 ppm. It’s also important to note that shocking the pool should not be a substitute for regular maintenance, such as regular testing and adjusting of the water chemistry, cleaning the pool, and vacuuming the bottom.

 

The length of time that a pool pump should be run depends on a number of factors, such as the size of the pool, the type of filter, and the desired water turnover rate.

As a general rule, the pool pump should run long enough to turn over the entire volume of water in the pool at least once per day. This is known as the turnover rate and it helps to ensure that the water is properly filtered and circulated.

For example, for a pool with a volume of 20,000 gallons and a pump with a flow rate of 50 gallons per minute, the pump should run for approximately 8 hours per day.

A general guideline is to run the pool pump for 8-12 hours per day, but this can vary based on the specific needs of your pool and the equipment you have. It’s also important to note that the pump should be run during the peak hours of sun exposure, to help prevent algae growth.

It is recommended to consult the manufacturer’s instructions or consult a pool professional to determine the appropriate turnover rate and run time for your specific pool and equipment. Additionally, it’s important to monitor the energy consumption of the pool pump and adjust the run time if necessary to minimize energy costs.

 

Yes, it is important to regularly brush your pool to keep it clean and free of debris. Brushing your pool helps to remove dirt, algae, and other contaminants that may accumulate on the walls and floor of the pool. This is important for maintaining the appearance of the pool and keeping the water clean and clear.

Brushing also helps to prevent the buildup of algae and other microorganisms that can cause discoloration and cloudy water and can also lead to problems with the pool’s filtration system.

It’s recommended to brush the pool’s walls, floor and steps at least once a week, or more frequently if the pool is heavily used or if there are a lot of leaves or other debris in the pool. It’s also important to use the correct type of brush for the surface of the pool (plaster, tile, vinyl, etc) and to use a brush with stiff bristles to remove tough stains and algae.

It’s also important to note that brushing alone is not enough, regular vacuuming and skimming are also needed to maintain a clean pool.

 

If the water level in your pool drops, there are a few things you can do to address the issue:

1. Check for leaks: The most common cause of a low water level is a leak in the pool structure or plumbing. Look for any obvious signs of water loss, such as wet spots or cracks in the pool walls or floor.
2. Check the skimmer and pump baskets: Make sure the skimmer and pump baskets are not clogged with debris, which can impede water flow and cause the water level to drop.
3. Check the water level in the pool: Check if the water level is below the skimmer. If it is, water is not flowing into the pool fast enough.
4. Check the pool filter: Make sure the pool filter is clean and not clogged with debris. If so, wash or change the filter.
5. Check pool water balance: If none of the above steps solve the problem, it’s possible that your pool’s water balance is off. Test your pool water and adjust the pH, total alkalinity, and chlorine levels as needed.
6. Add water as needed: If you’re unable to identify the cause of the low water level, simply add water to the pool to bring the level back to normal.

If the problem persists you may want to contact a professional pool service for further assistance.  

Yes, too much chlorine can damage a pool. Chlorine levels that are too high can cause a number of issues, including:

1. Corrosion of metal parts: High levels of chlorine can cause corrosion of metal parts, such as ladders and railings, which can lead to rust and other damage.
2. Damage to pool surfaces: High levels of chlorine can cause discoloration or fading of pool surfaces, such as plaster or tile, and can also cause damage to pool liners.
3. Irritation to skin and eyes: High levels of chlorine can cause irritation to the skin and eyes, which can be uncomfortable and even painful for swimmers.
4. Loss of effectiveness: High levels of chlorine do not have a higher sanitizing effect, it can actually make it less effective since it can form chloramines, which are less active than chlorine molecules, and can cause the chlorine to lose its ability to kill bacteria and other microorganisms.
5. Environmental damage: High levels of chlorine can also have a negative impact on the environment, as it can be harmful to plants and wildlife.

It is important to regularly test the chlorine levels in a pool and adjust as necessary to ensure that they are within the appropriate range (1-3 ppm). It is also important to maintain the appropriate pH level in the pool, between 7.2-7.8, to ensure that chlorine is working efficiently.  

Yes, sunlight can remove chlorine from water. Sunlight, specifically ultraviolet (UV) radiation, can break down chlorine molecules, reducing the amount of chlorine in the water. This process is known as “photolysis”. The rate of photolysis increases with the intensity of the UV radiation, which is why chlorine levels in a pool can decrease more quickly on sunny days.

The rate of photolysis also depends on the pH level of the water. The higher the pH level, the less effective chlorine is, and the more quickly it will break down. This is why it’s important to maintain the appropriate pH level in a pool, between 7.2-7.8, to ensure that chlorine is working efficiently.

It is important to note that the amount of chlorine loss is not only due to the sun, but also to the temperature, the number of swimmers, and the level of contaminants in the water. Therefore, it’s important to regularly test and adjust the chlorine levels in a pool, especially on sunny days, to ensure that the water remains safe to swim in.

 

Pools can turn green after rain due to an increase in the number of algae spores that are present in the water. Rain can wash algae spores into the pool from the surrounding area, where they can then grow and multiply. Additionally, heavy rain can also cause the pH level of the pool water to fluctuate, which can create an environment that is more conducive to the growth of algae.

The chlorines level can also decrease during heavy rain, which can contribute to the growth of algae. Finally, heavy rain can also cause a large amount of debris to enter the pool, which can provide a food source for algae. This is why it’s important to keep the pool cover on during heavy rain to reduce the amount of debris that enters the pool.

 

It is generally not recommended to drain a pool during heavy rain, as it can put added stress on the pool structure and surrounding area. Draining a pool during heavy rain can also increase the risk of ground shifting and settling, which can cause damage to the pool and surrounding decking. Instead, it’s better to wait until the rain has stopped and the ground has had time to dry out before draining the pool. Additionally, if you have a pool cover, it’s important to keep it on during heavy rains to reduce the amount of debris that enters the pool.

 

To keep your pool cover clean, you should regularly remove debris such as leaves, twigs, and dirt using a pool cover pump, leaf rake, or pool cover vacuum. You can also use a mild detergent and a soft-bristled brush to gently scrub away any stains or discoloration. Rinse the cover thoroughly with a hose or pressure washer to remove any remaining dirt or soap. It’s also a good idea to keep the cover tightly secured when not in use to prevent debris from accumulating on it. Additionally, you can use a pool cover cleaner to help remove dirt, grime, and mold.

 

When closing your pool for the winter, it’s important to properly store and handle your pool chemicals to ensure they remain safe and effective for use next season. Here are a few steps you can take to prepare your pool chemicals for winter:

1. Use up remaining chemicals: Before closing your pool, use up any remaining chemicals, such as chlorine or algaecide, to prevent them from losing potency over the winter.
2. Store chemicals in a cool, dry place: Once you have used up the remaining chemicals, store the rest of your chemicals in a cool, dry place, such as a garage or shed. Avoid storing chemicals in damp or humid areas, as this can cause them to degrade or become unstable.
3. Keep chemicals away from heat sources: Do not store chemicals near heat sources, such as a furnace or hot water heater, as this can cause them to become unstable or even explosive.
4. Keep chemicals out of reach of children and pets: Store chemicals in a secure place, out of reach of children and pets, to prevent accidental ingestion or injury.
5. Follow the manufacturer’s instructions: Always follow the manufacturer’s instructions for storing and handling pool chemicals, as different chemicals may have different requirements.
6. Keep the chemicals in their original container: Do not transfer pool chemicals to other containers, as this may lead to confusion later on and could cause you to overdose on the pool.

By following these steps, you can help ensure that your pool chemicals remain safe and effective for use next season.
