How do I know if I need to install a backflow preventer?

Residential customers are only required to install a backflow preventer if there is a potential cross connection hazard. It is the customer’s responsibility to notify us if an irrigation system or pool is installed. Backflow requirements vary for commercial/industrial customers based on the business’s water use. Sandy’s Water Department staff reviews newly established commercial/industrial water accounts to assess the degree of backflow hazard and notifies businesses about backflow requirements.
