Water Differences and Dissolved Solids: How is RO Water different from tap water? How will I know the RO System is removing Dissolved Solids from my tap water?Updated 2 months ago

The biggest difference from tap water and evidence the system is functioning is in the taste and clarity of the water produced. Cooking, coffee, drinks, and juices made with RO water will taste better. Ice cubes made with RO water are harder, clearer, and last much longer.

Ice Test: If you take two similar glasses and put ice cubes made with RO water in one and the same number of ice cubes made from tap water in the other, you will notice that it takes longer for the RO ice cubes to melt. When you melt tap water ice cubes you usually see sediments on the bottom of a glass. This doesn’t happen with RO water.

Conductivity Test: Another way of determining the amount of dissolved solids removed from tap water is by using a conductivity meter. This meter measures the conductivity which dissolved solids create in water. The meter will tell you the parts per million of Total Dissolved Solids (TDS). Express Water offers a water sample kit for the testing of a customer's water to determine how the RO Membrane is working. It can also help to determine when to replace the membrane.
