Helpful answers before scheduling.
When might a backflow assembly need replacement?
Replacement may be considered when an assembly is badly deteriorated, damaged, obsolete, incorrectly sized or uneconomical to repair. The site and authority requirements guide the final scope.
What information should I provide for an installation?
Share the property address, water authority, notice or plan details, assembly type and size when known, photos of the location and any access constraints.
Does a new assembly need testing?
Testing and reporting requirements depend on the water authority and installation. Scylla can review the available notice or project information and coordinate the applicable next step.
