Non-Potable Backflow Devices

When water is being reused, it is referred to as non-potable. This can include lake or pond water, collected rainwater or recirculated water. A non-potable backflow preventer will visually indicate to others that the water in use in non-potable and therefore unsafe for consumption. Non-potable backflow preventors operate the same way a standard backflow preventor would, they have purple caps installed on them for identification.
