Water Treatment FAQ's

Will my water taste salty?


No! Water softeners use water to change ion charges of elements in the water to make the water "soft." Softeners add salt but such a small amount that you will never taste it!

What Is Reverse Osmosis?


A Reverse Osmosis system forces water, under pressure into a module that contains a semipermeable membrane and a carbon filter to remove impurities.

Whether it’s an unpleasant smell or a bad taste, hard water that is increasing your utility bills or a simple desire for convenient, quality drinking water we are here to help. Water Treatment can benefit any part of your home from spot free dishes to cleaner, softer laundry, noticeably cleaner skin and longer lasting appliances! Ask our specialists about testing your water!

Yes! A properly calibrated RO system will remove 99% of all salt added by water softeners.
