How Often Should You Regenerate Your Water Softener?

If you’ve noticed an odd noise in your mechanical room or the utility closet, that is probably your water softener regenerates. But then how often do you hear this sound, do you hear it regularly or do you seldom notice? And do you take note of how often this sound comes on? One important question that we ask when using a water softener, is how often it should regenerate. But first, what is water softener regeneration?


A water softener operates with a method of ion exchange. This process involves hard water being passed over a bed of resin and this secures the hardness of the water, bringing about magnesium and calcium ions. The resin would become overwhelmed and saturated as time goes by, and so it must be regenerated or in simpler words, recharged. When a water softener is being regenerated, the process involves salt removing the minerals from the resin. This process revitalizes your water softener and this keeps it operating competently.

How Often Should You Regenerate It?

With the definition and explanation above, it is quite obvious that regular and frequent regenerations are necessary to keep your water softener working efficiently and keep the resin bed fully functional. Regeneration should occur generally every two or three days although this is determined by some factors that should be put into consideration. A quality water softener would regenerate automatically and can even do so more than twice a day or every day in a week.

Factors That Determine How Often Your Water Softener Should Regenerate

  1. The amount of iron in your water is an important factor. If you have high levels of iron in your water, your resin bed would work twice as hard in softening your water and then you would have to regenerate it often to keep it working efficiently.
  2. The same goes for the hardness of your water. A water softener is important because it turns the hard water in your home into soft water. If your water is very hard, your water softener would have a lot of work to do and hence, it would need frequent regeneration.
  3. The capacity of your resin tank is also important. If your resin tank does not carry a lot of water, there would be no need for constant regeneration.
  4. The water intake of your home is also as important. The amount of water that goes through your water softener determines how often it needs to regenerate and when your water intake increases, the regeneration would have to be more often.
  5. You also have to consider the age of your system. An older system would have to regenerate often.

You also have to look out for the type of control valve that your water softener uses, because this determines the rate at which your water heater regenerates. Some water softeners include a clock that would regenerate at your stipulated desired time. You should regenerate your water in the middle of the night so that you can avoid having untreated water in your home during the day.
