The most common solution where people have legitimate concerns about such
thing (such as an underlying pathosis) is to provide a water source for
cooking that bypasses the softener. This allows for softened water to be
used for toilets, bathing, laundry, dishwashing, and other hygiene purposes.
Water for drinking, cooking, and preparing beverages can come from the tap
that bypasses the conditioner. Another method of purification can be
employed at the point of consumption such as reverse osmosis that supplies
conditioned water that doesn't have added salts. Of course, drinking the
unconditioned tap water is also an option as is purchasing bottled water.
