Water softeners come in various sizes, and making sure that you have the right size for your home is important. Getting the right size will allow you to make sure that you can soften your water sufficiently without losing efficiency and wasting extra water and salt by regenerating too often. The best way to accurately size your water softener is to work directly with a Culligan water expert to test your water, assess your flow rate and determine how much water your household uses on a regular basis. Generally speaking, harder water, higher water consumption and a greater number of taps running simultaneously mean that you’ll need a larger water softener. You don’t want to overshoot, though. Regular regeneration is also still required for optimal performance. Plus, larger units tend to cost more, meaning that purchasing an oversized softener might result in spending more money upfront than is necessary.
