Understanding the NWS Control Flow AIO 12"x52" Iron System
The NWS Control Flow AIO 12"x52" Iron System is designed to provide high-capacity, salt-free iron filtration for whole-house treatment. Its large 12-inch diameter polyglass tank houses 1-3/4 cubic feet of iron-reduction media, making it suitable for homes with significant iron levels. The system utilizes air injection oxidation to convert dissolved iron into a solid form, which is then filtered out by the media bed. This process eliminates the need for salt and chemical feed, simplifying maintenance and reducing ongoing costs.
Important Maintenance Schedule
Regular maintenance ensures optimal performance and longevity of your iron filtration system. The system’s control valve utilizes Control Flow Technology, which automatically meters backwash cycles based on household water usage. Nonetheless, routine manual inspections and occasional media replacements are recommended to maintain efficacy.
Routine Inspections
- Monthly: Check the control valve for any alerts or irregularities on the display (if applicable). Inspect for any visible leaks or water flow issues.
- Every 3 to 6 months: Visually inspect the system tank and control valve for signs of wear or buildup. Ensure the bypass valve operates smoothly during maintenance checks.
Media Replacement Schedule
The iron-reduction media is a consumable component that typically requires replacement over time. Its lifespan depends on water chemistry and usage levels. While the system is designed for low-maintenance operation, the following guidelines will help maintain peak efficiency:
- Every 3 to 5 years: Plan to replace the entire 1-3/4 cubic feet of iron-reduction media. This will restore the system’s capacity to remove dissolved iron and maintain water quality standards.
- Upon detection of issues: If you notice a decline in water quality, increased staining, or reduced flow, consider inspecting the media bed and replacing media sooner.
Consumable Replacement Process
Replacing the iron-reduction media involves a few key steps, best performed by a licensed professional or a knowledgeable homeowner familiar with water treatment systems:
- Preparation: Turn off the main water supply to the system. Close the control valve and drain any residual water from the tank if necessary.
- Disconnect the tank: Remove the plumbing adapters and carefully detach the tank for media replacement.
- Remove used media: Shake or gently drain the old media out of the tank, being cautious of dust or residual particles.
- Refill with new media: Add the fresh 1-3/4 cubic feet of iron-reduction media, ensuring it is evenly distributed and filled to appropriate levels.
- Reassemble: Reattach the tank, reconnect plumbing adapters, and ensure all connections are tight and leak-free.
- System restart: Turn the water supply back on and initiate a backwash cycle if necessary, to settle the media and remove any debris.
Post-Media Replacement Tips
- Check for leaks around connections and tank seals before restoring full water flow.
- Monitor water quality and system performance over the first few days after replacement, looking for signs of proper operation and iron removal.
- Adjust the control valve settings if your system allows for flow rate modifications, ensuring optimal backwash timing and interval.
Maintaining Your Iron Filter for Longevity
Consistent, scheduled maintenance will extend the life of your system and ensure continued protection against iron-related issues. Regular inspections, timely media replacements, and attentive operation will keep your water clear and your plumbing free of staining and buildup.
To simplify maintenance, keep records of all inspections, media changes, and system adjustments. This allows you to track the system’s performance over time and anticipate upcoming service needs.
Pre-treatment and filtration order
The sequence of treatment stages in water filtration is crucial for addressing high iron levels effectively. In regions where iron content in the water is significant, pre-treatment systems can be beneficial. By addressing any sediment or larger particles first, a whole-house system like the Fleck 5600SXT 48,000 Grain Water Softener can then focus on softening and iron removal without being hindered by additional contaminants. This order ensures that the filtration media remains clean and performs optimally.
An appropriate pre-treatment process may include sediment filtration or a sediment trap, which can capture larger particles before they reach the iron filtration system. When this step is neglected, larger particles may prematurely clog the media bed, reducing the overall efficiency and lifespan of the system. Proper sequencing of filtration and treatment stages not only enhances iron removal but also improves the quality of water throughout the home, ensuring that appliances and plumbing systems are protected from the corrosive effects of untreated water.
