Is softener water suitable for drinking?
Most water softeners use ion exchange resin, which is suitable for potable use. However, the taste may be changed, and more important is that the level of sodium dissolved in the water will increase. There are recommended levels of sodium for drinking water so you should check that the level of hardness in the water, when replaced by sodium in the water softener, does not add to the base level of sodium so much that the sodium exceeds recommended limits. Usual practice is to have a take-off point for drinking before the inlet to the water softener.
