The Aquasure Harmony Series 72,000 Grains Water Softener can process a variable amount of water depending on your source water’s hardness, but it is designed to handle the needs of a large household with up to 6+ bathrooms.
The 72,000-grain capacity refers to the amount of hardness the system can neutralize before it triggers a regeneration cycle. Because this capacity is based on grains of hardness rather than a fixed monthly gallon total, the actual volume of water processed depends entirely on your specific water quality. You must determine your source water’s hardness level in grains per gallon (GPG) to calculate your specific usage. This calculation is vital for water softener buyers because exceeding the system’s design limits leads to hard water breakthrough, resulting in scale buildup on fixtures and appliances. The Aquasure Harmony Series was selected for our comparison because it provides a high-capacity threshold suitable for larger residential footprints. The unit features an automatic digital metered control head to manage these cycles based on actual usage.
What to Check Before Buying the Aquasure Harmony Series
Before purchasing this water softening system, confirm these technical requirements to ensure the unit functions correctly in your specific plumbing environment.
- Verify your source water hardness in grains per gallon (GPG) to ensure it falls within the 72,000-grain capacity limits.
- Measure the available clearance in your utility space to ensure the fiberglass-lined polyethylene tank fits the designated area.
- Confirm your home’s flow rate (GPM) to ensure the water has sufficient contact time with the prefilled premium-grade resin.
- Check the required salt type and consumption rate in the manufacturer’s documentation to manage ongoing maintenance costs.
- Verify that your plumbing has the necessary pressure and a bypass valve to allow for maintenance and proper operation.
Comparing the Aquasure Harmony Series to Other Water Softeners
The Aquasure Harmony Series is a high-capacity water softener, which is a system that uses resin beads to remove calcium and magnesium minerals from your home’s water supply. This specific model is positioned for users with high-demand requirements, such as large estates or homes with many bathrooms. If you have a smaller home with low water usage or very soft source water, you might find a lower-capacity unit more cost-effective. However, for households requiring heavy-duty performance to prevent scale buildup, the 72,000-grain capacity provides a significant buffer against frequent regeneration cycles.
If you have a large household with 6 or more bathrooms and need a high-capacity system to handle significant mineral content, the Aquasure Harmony Series is the appropriate choice.
