A third type of management makes use of a mechanical water meter to measure Drinking water utilization and provoke recharging. The benefit of this system is that no electrical parts are required and the mineral tank is simply recharged when mandatory. When it is geared up with two mineral tanks, softened water is always available, even when the unit is recharging.

The federal government has established regulatory limits (standards) on over a hundred chemical and microbial contaminants in drinking water.

Many states have established their own standards, which should be at least as stringent because the federal standards.
