How much water can the Tannin 5600 SXT Water Softener treat?

The Tannin 5600 SXT Metered Water Softener can treat 48,000 grains of hardness and tannins before it requires a regeneration cycle. This capacity is sufficient for a standard 3-bedroom household with moderate water hardness, but it may require more frequent regeneration if your well water contains high levels of tannins.

The 48,000-grain capacity is a specific volume of treated water based on the resin’s ability to exchange ions. Because tannins can clog resin beads faster than standard hardness, the actual amount of water treated depends on your specific tannin concentration. We selected the Tannin 5600 SXT for our comparison because it offers a high 14 gallons per minute (GPM) flow rate, ensuring the system does not starve the house of water during the regeneration cycle. You should verify if your water contains high levels of iron or manganese, as these minerals can foul the resin and reduce the effective capacity more rapidly than tannins alone. For specific requirements regarding salt types or local chemistry limits, consult the manufacturer’s support page or the provided manual.

What to Check Before Buying the Tannin 5600 SXT

Before purchasing this water softener, you should confirm these technical requirements to ensure the unit performs correctly in your home.

• Verify the physical footprint and plumbing clearance for both the brine tank and the valve head to ensure they fit your designated space.
• Confirm the specific salt type required, such as pellets or crystals, to prevent salt bridging and ensure effective regeneration.
• Determine if your water requires additional pre-filtration for iron or manganese to prevent resin fouling.
• Check the flow rate during the regeneration cycle in the manual to ensure it meets your household’s water demand.
• Identify the specific maintenance schedule for the metered valve to ensure accurate usage tracking and prevent under-softening.

Comparing the Tannin 5600 SXT to Other Softeners

The Tannin 5600 SXT is a specialized water treatment system designed to remove both hardness and organic tannins from well water. This unit sits in a middle-to-high range of capacity, making it suitable for standard residential use. If you have a large estate or require high-flow irrigation, you might need a system with a higher grain capacity, such as 72,000 grains, to prevent frequent regeneration. Conversely, if your water has very low tannin content and only requires basic softening, a smaller, more compact unit might be a more cost-effective choice for your space.

You should choose the Tannin 5600 SXT if you have a standard-sized home with well water that contains both mineral hardness and visible tannins.
