PUV-7 Water Softening And Filtration

The PUV-7 water softening and filtration system is an efficient and cost-effective way to remove hardness from your water. It uses a special ion exchange process to remove calcium and magnesium, the two minerals responsible for making water hard. This process also filters out dirt, sediment, rust, pesticides, and other contaminants that could be present in your water supply. The PUV-7 is designed for homes, businesses and industrial applications and can be easily installed on existing plumbing systems. It also requires minimal maintenance to keep it running efficiently. The PUV-7 has adjustable settings to customize the hardness removal required for your needs. 

PUV-7 Water Softening And Filtration

PUV-7 water softening and filtration is a process that utilizes advanced technology to remove harmful contaminants, hardness minerals, and other impurities from drinking water. It uses an ion exchange system for its main function of softening water. This process also filters out sediments, viruses, bacteria, chlorine and other chemicals that affect the quality of your water. Hardness levels are measured in grains per gallon (gpg).

When water hardness is high, it can lead to scale buildup on surfaces and clogged pipes. This affects the efficiency of your appliances and plumbing system, which can cost you more money in the long run. Hard water may also contain unhealthy toxic substances such as lead, chlorine, arsenic, and nitrates.

The PUV-7 Water Softening System

The PUV-7 water softening system is an advanced, high-tech water filtration and softening solution. The system combines filtration and reverses osmosis to reduce hardness, impurities, and sediment, delivering clean and safe drinking water. It features a multi-stage filtration process that removes 95-98% of contaminants from the water.

The PUV-7 system also features a reverse osmosis process, which softens the water by removing minerals like calcium and magnesium that cause hardness in tap water. This process reduces contaminants such as chlorine and lead, producing safe drinking water.

The PUV-7 Water Filtration System

The PUV-7 Water Filtration System is a highly efficient, lightweight and compact unit designed for use in both residential and commercial applications. It utilizes the latest technological advances to provide safe, clean drinking water.

The PUV-7 Water Filtration System works by trapping and removing unwanted particles from the water using a combination of sediment filtration, chemical adsorption, ion exchange and reverse osmosis. The system utilizes seven filtration stages to remove all contaminants, including heavy metals, bacteria, viruses and other impurities.

The components of the PUV-7 Water Filtration System include a pre-filter, sediment filter, activated carbon filter, chemical adsorption filter, ion exchange resin and reverse osmosis membrane. All filters are designed to remove different types of contaminants for maximum efficiency.

Choosing The Right PUV-7 Water Softening And Filtration System

  • Cost: Make sure to consider the total cost of the system, including installation and any additional components or services that may be required.
  • Efficiency: Look for an energy-efficient system with advanced filtration capabilities. This will help ensure optimal performance and reduce electricity bills in the long run.
  • Maintenance: Consider the maintenance requirements of the system. Look for systems designed to be easy to use and maintain to enjoy clean, soft water with minimal effort.
  • Durability: Ensure the system is made from durable materials and has a long service life. This will ensure that your PUV-7 system will last many years.
  • Quality: Look for a system tested and certified by the Department of Health and Human Services. This ensures that the system meets the highest standards in terms of quality and performance.

How To Replace A UV Lamp?

Step 1: Unplug the power cord from the outlet before replacing the UV lamp.

Step 2: Loosen the screws on top of the PUV-7 to open its lid and expose the UV chamber.

Step 3: Lift out the old UV lamp and set it aside.

Step 4: Clean the quartz sleeve with a damp cloth or cotton swab. This will help ensure the maximum effectiveness of your UV light.

Step 5: Insert the new lamp into the chamber, then secure it with screws from the top of PUV-7.

Step 6: Plug the power cord back into the outlet and restart the operation of the PUV-7 water softening and filtration system.

Troubleshooting A PUV-7 Water Softening And Filtration System

  • Pressure drop: When it comes to pressure drop, you should check if you notice a decline in water pressure in the filter cartridge. Ensure it has been washed and replaced regularly per the manufacturer’s instructions. You can also inspect the valves and ensure they have not been clogged or damaged due to sediment buildup.
  • High bacteria counts: The high bacteria count in the system can be due to the breaking through the sediment filter. You should test the source water to ensure the water quality.
  • Water appears milky: This could be due to air bubbles in the water, which are often caused by high levels of calcium carbonate. Run the water until the air is purged.
  • Unit leaking water: If your PUV-7 unit is leaking water, there are several steps you can take to identify and fix the issue. Check for any loose or damaged hoses causing the leak. If these appear to be in good condition, then it is likely a malfunctioning internal component, such as the valve or gasket.
  • System shutting down intermittently: If the system begins to shut down intermittently, check for any signs of blockage or debris buildup in the filter screens. This can cause the system to stop running. Additionally, check the system valves and pipes to ensure no signs of leaking or clogging.


Can PUV-7 water softening and filtration systems remove all impurities from water?

PUV-7 water softening and filtration systems can reduce hardness levels, iron, manganese, and other dissolved minerals through an ion exchange process. However, they cannot remove contaminants such as chlorine and microbial particles from the water.

Can PUV-7 water softening and filtration systems be used in commercial settings?

Yes, many businesses and industries use PUV-7 water softening and filtration systems. The system is designed to handle large amounts of water, so it is ideal for commercial settings such as restaurants, hotels, hospitals and factories that require a high volume of clean water.

Des the UV filter go before or after the pressure tank?

The placement of the UV filter depends on what type of water-softening system you use. In most cases, it’s best to place the UV filter after the pressure tank. This ensures the water is already softened and filtered before entering the tank, protecting your system from harmful contaminants. It also reduces any potential buildup in the pressure tank, which can cause it to malfunction.

Can you install a water filter with a water softener?

Yes, you can install a water filter with a softener. This is especially recommended to ensure your drinking water is safe and clean.


PUV-7 water softening and filtration is an efficient system that provides great advantages to households. Its seven-stage filtration process eliminates sediments, contaminants, and other impurities, ensuring the delivery of clean drinking water. It also reduces hard minerals like calcium and magnesium in the water, making it softer and easier to use in various houseexcellentactivities. PUV-7’s advanced design and quality materials make it a worthwhile investment for any home, as it ensures the delivery of clean, safe water on demand. With its durable construction and easy maintenance options, households can enjoy clean drinking water without worrying about high costs or frequent repairs.
