RDZ Plumbing and Drains is a Latino-owned, women-owned plumbing company on 36th Street in Normal Heights, San Diego, founded in 2018 by Salvador Rodriguez with a scope covering residential and commercial drain cleaning, sewer camera inspection, hydro jetting, and pipe lining. The company was featured on the cover of Cleaner magazine, a plumbing industry trade publication, for its adoption of high-technology pipelining equipment that allows trenchless sewer rehabilitation without excavating yards or driveways. Hydro-jetting service uses pressurized water at rates sufficient to cut through grease buildup, mineral scale, and root intrusion in sewer mains — a non-chemical approach that preserves the structural integrity of aging clay and cast-iron laterals common in the Normal Heights housing stock. Mechanical-system coordination on larger projects pairs RDZ's drain and gas-line work with HVAC contractors, and California Pro Heating and Air Inc. in adjacent North Park handles the ductwork and air-handler side on whole-house retrofits that touch both the water and air systems. Sewer camera inspection deploys a push-rod camera through the lateral to map joint offsets, belly sections, and root penetration points, producing a recorded video that homeowners and insurance adjusters can review frame by frame. The 92116 address on 36th Street places the shop in the eastern section of Normal Heights near the border with Kensington, where Adams Avenue bends toward Marlborough Drive and the residential streets carry some of the oldest sewer infrastructure in the neighborhood. Boiler and radiator plumbing is an additional specialty — an uncommon offering in San Diego's mild climate, but one that serves the Craftsman and Spanish Colonial homes in Normal Heights and University Heights where original hydronic heating systems are still in service. Commercial drain maintenance covers high-volume water-use tenants on the Adams Avenue and El Cajon Blvd corridors, and Corner Wash on Adams Avenue runs the kind of multi-machine laundry operation where grease-trap buildup and lint-clogged drain lines require quarterly jetting to prevent backups. Gas-line repiping addresses corroded or undersized black-iron runs that cannot support modern high-BTU appliances, a condition common in the 1940s and 1950s homes that line the residential streets between Adams Avenue and Meade Avenue. The team is bilingual in English and Spanish, serves HOAs and property management companies across San Diego County, and provides emergency response around the clock with same-day estimates.
