Some customers express concern about this process potentially being wasteful. Overall, though, the benefits of using a water softener far outweigh any potential downsides.
Yes, the systems use a lot of water during regeneration — but they also save you water on things like laundry and washing dishes. Fairly quickly after installing a water softener, you should develop an understanding of its regeneration schedule. For one, if your softener regenerates based on demand, your water usage may have changed. If it regenerates on a time-based schedule, you may have accidentally adjusted the settings at some point.
In the latter case, refer to the manual for information on how to reset the schedule. Another common cause is an empty brine tank. You may have forgotten to refill the tank with salt pellets at some point. The salt inside may have also formed a bridge , which disguises how empty the tank really is. Remember, this schedule relies on the salt in your brine tank. Demand regeneration allows the water softener to be cleansed only when the softening capacity of the resin beads has been used up.
On the other hand, the time-initiated regeneration process could filter the water well before or after the resin beads have been used up. The majority of water softeners are designed to begin the regeneration process at 2AM, which means that the process will likely end around 4AM. The time between each regeneration depends on household water use and overall water hardness levels.
Keep in mind that the water softener must have a water reserve capacity of around 25 percent before the regeneration process can take place. At this reserve capacity, the resin beads will be at a 75 percent saturation rate , which means that the beads contain around 75 percent of the total amount of hardness minerals they can accommodate.
If the water softener is designed to accommodate a family of four, you can expect the regeneration process to use anywhere from gallons of water. However, the number of hardness minerals in the water will also determine how much water is used during regeneration.
Instead of calculating how often your water softener should regenerate, you can set it and forget, enjoying predictably soft water on a daily basis. Resin beads in the tank attract and hold onto hard water minerals, removing them from the water.
Softened water exits the tank and flows to the plumbing throughout your home. The Chemistry of Regeneration During the softening cycle, sodium on the resin beads is exchanged for hard water minerals in the water. Here are the typical water softener regeneration steps:. The number of litres used for each regeneration is dictated by the design of the water softener, its size, and efficiency.
The water softener needs a specific amount of salt to complete the regeneration. For example, the HarveyArc needs grams of salt for each regeneration. The brine solution in the bottom of the cabinet is saturated with salt. So, 0. This concentrated brine is diluted with more water as it is injected into the water softener during regeneration. In fact, the brine injector works on the venturi principle; as water goes through the injector it creates a vacuum.
This then sucks the brine into the injector as it passes into the water softener.
