San Jose Water backflow repairs
San Jose Water tests backflow assemblies for its customers itself, at no charge. You don’t need to hire a tester for the annual test. When a device fails, BackflowCare makes minor repairs in San Jose, Campbell, Los Gatos and Saratoga. Moving or replacing a device takes a licensed plumbing contractor, and we can refer you to one we trust.
