Questions and Answers
  • 1. 

    Most health agencies prohibit ozone in the pool water because:

    • A.

      It makes the water a strange color.

    • B.

      It is such a powerful oxidizer.

    • C.

      It has a dangerous reaction to chlorine.

    • D.

      All of the above.

    Correct Answer
    B. It is such a powerful oxidizer.
    Explanation
    Ozone is prohibited in pool water by most health agencies because it is a powerful oxidizer. Ozone has the ability to break down and destroy organic matter, including bacteria and viruses, making it an effective disinfectant. However, its strong oxidizing properties can also be harmful to humans and can cause irritation to the skin, eyes, and respiratory system. Therefore, health agencies discourage the use of ozone in pool water to ensure the safety and well-being of swimmers.

    Ultraviolet radiation is an attractive option for aquatics facilities because:

    • A.

      It has the ability to destroy crypto.

    • B.

      It has been used for years to augment chlorine disinfection.

    • C.

      It can reduce chloramines.

    • D.

      All of the above.

    Correct Answer
    D. All of the above.
    Explanation
    Ultraviolet radiation is an attractive option for aquatics facilities because it has the ability to destroy crypto, which is a harmful microorganism. Additionally, it has been used for years to augment chlorine disinfection, enhancing the effectiveness of the disinfection process. Furthermore, ultraviolet radiation can also reduce chloramines, which are undesirable byproducts of chlorine disinfection. Therefore, all of the given options are correct reasons for why ultraviolet radiation is an attractive option for aquatics facilities.

    The most critical measures automatic controllers make of water quality are ORP and pH.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Automatic controllers measure ORP (oxidation-reduction potential) and pH as the most critical measures of water quality. ORP indicates the presence of oxidizing or reducing agents in the water, which can affect its quality. pH, on the other hand, measures the acidity or alkalinity of the water, which is another important factor in determining water quality. Therefore, it is correct to say that ORP and pH are the most critical measures of water quality.

    Reasons to consider a new automatic control include:

    • A.

      It’s critical to monitor dozens of variables in today’s facilities.

    • B.

      Controllers only last a few years before they go bad.

    • C.

      Wireless options and new sensing probes offer superior technology.

    • D.

      None of the above.

    Correct Answer
    C. Wireless options and new sensing probes offer superior technology.
    Explanation
    The reason to consider a new automatic control is because wireless options and new sensing probes offer superior technology. This means that by using these options, facilities can have more advanced and efficient monitoring systems. Additionally, the statement mentions that controllers only last a few years before they go bad, which further supports the need for a new automatic control. The other options mentioned, monitoring dozens of variables and none of the above, do not directly provide a reason to consider a new automatic control.

    The three types of chemical feeders are liquid; dry and erosion feed; and in-line chlorine generation.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because there are indeed three types of chemical feeders: liquid feeders, dry and erosion feeders, and in-line chlorine generation feeders. These feeders are used in various industries and applications to introduce chemicals into a system or process. Liquid feeders involve the use of pumps to inject liquid chemicals, while dry and erosion feeders use solid chemicals that dissolve or erode over time. In-line chlorine generation feeders produce chlorine on-site through electrolysis. Therefore, the given statement is correct.

    Chemical  feed systems require careful maintenance because:

    • A.

      Varying bather loads make them go out of whack.

    • B.

      They carry high pH chemicals under pressure.

    • C.

      Most are simply not made well.

    • D.

      Chemical feed systems actually rarely need maintenance.

    Correct Answer
    B. They carry high pH chemicals under pressure.
    Explanation
    Chemical feed systems require careful maintenance because they carry high pH chemicals under pressure. The high pressure can cause leaks or damage to the system, while the high pH chemicals can be corrosive and cause deterioration of the system components. Regular maintenance is necessary to ensure the system is functioning properly and to prevent any potential hazards or malfunctions.

    An NSF certification is nice to have for filters, but most health agencies don’t require it.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    An NSF certification is not just "nice to have" for filters, but it is actually required by most health agencies. This means that the statement "most health agencies don't require it" is incorrect. The correct answer is False.

    Higher than normal pressure ratings on DE filters usually means:

    • A.

      The element covers themselves have become soiled or clogged.

    • B.

      It’s time to get a new filter, because this one is broken.

    • C.

      The pressure gauge is malfunctioning.

    • D.

      All of the above.

    Correct Answer
    A. The element covers themselves have become soiled or clogged.
    Explanation
    Higher than normal pressure ratings on DE filters usually means that the element covers themselves have become soiled or clogged. When the filters are dirty, the flow of water through the filter is restricted, causing an increase in pressure. This indicates that the filter needs to be cleaned or replaced to maintain proper filtration. The other options, such as getting a new filter or the pressure gauge malfunctioning, are not necessarily the cause of the higher pressure ratings.

    What are the two most critical elements to proper heater function?

    • A.

      Proper water quality balance.

    • B.

      The temperature inside or outside.

    • C.

      Proper efficient combustion and correct water flow.

    • D.

      None of the above.

    Correct Answer
    C. Proper efficient combustion and correct water flow.
    Explanation
    Proper efficient combustion and correct water flow are the two most critical elements to ensure proper heater function. Efficient combustion ensures that the fuel is burned effectively, providing sufficient heat for the water. Correct water flow ensures that the water is circulated properly through the heater, allowing it to be heated efficiently. Without these two elements, the heater may not function effectively and may fail to provide the desired heating results.

    Dedicated gas-fired heaters are both the least expensive and longest lasting.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement claims that dedicated gas-fired heaters are both the least expensive and longest lasting. However, this is not necessarily true. While gas-fired heaters may be cost-effective and durable, there are other types of heaters that could be less expensive or have a longer lifespan. Therefore, the statement is false.

    What is the primary maintenance task for any pump?

    • A.

      Keeping parts properly lubricated.

    • B.

      Keeping the strainer basket clean.

    • C.

      Smelling for burning parts or gears.

    • D.

      All of the above.

    Correct Answer
    B. Keeping the strainer basket clean.
    Explanation
    The primary maintenance task for any pump is keeping the strainer basket clean. This is because the strainer basket is responsible for trapping debris and preventing it from entering the pump, which can cause damage and decrease its efficiency. By keeping the strainer basket clean, the pump can continue to operate effectively and prevent any potential issues caused by clogged or blocked filters.
