Backflow and Cross-Connections
Backflow devices are required on all industrial and commercial properties and many multi-family units to prevent the re-entry (backflow) of used water back into the potable water system. For full information, please reference North Las Vegas Municipal Code 123.20 Backflows and Cross-Connections reference and the Uniform Design and Construction Standards for Potable Water, including the addenda by visiting the links below.
The City of North Las Vegas requires testing of these devices not less than one-time per year.
