La Jolla is on the same water system as everyone else, built so water flows toward the properties and never back, and the backflow preventer at the connection points is designed to keep it that way. For La Jolla's residential properties, the device usually sits at the irrigation connection, protecting the supply from what landscape systems could otherwise send backward. For the businesses in the Village, the restaurants, the galleries, the medical offices, the buildings with fire systems, the devices get tested on a schedule, and the notices arrive in busy season and slow season alike.
A healthy assembly makes the test routine. An aging one, with worn valves, tired seals and some help from the coastal air, turns the notice into a job for a licensed contractor, with a retest once the repair is done. Properties here are kept in good shape, and the backflow device should be kept up the same way.
That's the service, performed by or under a licensed contractor, testing through repair through replacement, with clear updates and the tester's paperwork passed along to you. The idea is simple, the test gets done and the device gets kept up without it turning into an ongoing project for you.
