Rankin Plumbing & Repair in Bonita serves the Chula Vista area from a Bonita Road office, specializing in slab leak detection, drain cleaning, and water heater service for the residential properties along the Sweetwater Road corridor. Non-invasive leak diagnosis pairs electronic listening devices with thermal imaging cameras to distinguish between sub-slab pipe failures and exterior water intrusion — the latter typically routed to Chavez Family Roofing for flashing and membrane repair on the ranch-style homes common in 91902. The crew handles hydro-jetting for root-clogged sewer laterals, seismic gas shut-off valve installation per California Government Code Section 19210, and copper-to-PEX transitions in the older homes that line Bonita Road. Irrigation backflow-preventer testing and anti-siphon valve replacement at the meter connection are common add-ons for the large-lot Bonita properties serviced by Pro Lawn Care of Bonita. Highest-complexity work includes full-house PEX manifold repipes routed through attic spaces to restore water pressure in homes with original 1960s-era copper supply lines.
