# Premises isolation

A term used when buying car wash.

The backflow assembly on a wash's line, required because the premises are a cross-connection hazard.

Washington names car washes on its list of severe and high health cross-connection hazard premises requiring premises isolation, so the device is not a plumber's suggestion, it is the condition of having water. Testing follows installation, repair, reinstallation or relocation and then runs annually unless the water system asks for more, performed by a certified tester, and the water system keeps its records five years or the life of the assembly, whichever is shorter. The consequence is the part to price: where a consumer fails to comply with testing or repair, the purveyor's corrective actions include discontinuing water service. A tunnel with the water off is a closed business, so read the test file before the equipment list.
