Workflow

Confirm the irrigation system has the required assembly in place.
Choose a Lewisville-registered tester who can handle the actual device type.
Make sure the completed test is submitted through BSI within ten days.

Residential

Residential users usually hit this through irrigation systems and other hazards the City flags at the meter or within the property.
Not every listed tester can handle every device type, so homeowners need to match the tester to the assembly.

Commercial and managed properties

Commercial, industrial, multifamily, and managed properties should assume annual testing is part of recurring compliance once the City requires a device.
