Valley Industrial Specialties in Chula Vista operates a wholesale plumbing warehouse on North Glover Avenue, stocking over 10,000 repair parts, backflow-prevention devices, fixtures, tools, and safety gear across residential and commercial product lines. Founded in 1985, the independently operated corporation supplies trade plumbers and maintenance crews with hard-to-find, obsolete, and discontinued components that big-box retailers no longer carry — the same deep-inventory sourcing that supports complex drain and supply-line rebuilds at Solid Plumbing & Drains Inc. The Chula Vista location anchors a three-branch network that also serves El Cajon and the San Marcos corridor, giving South Bay contractors a local counter for same-day pickup on emergency parts. Hydronic heating components, backflow assemblies, and water-heater elements round out the catalog alongside HVAC crossover inventory stocked by mechanical contractors at Friar's Plumbing Heating and AC Repair. The warehouse carries brass, copper, PVC, CPVC, and PEX fittings from manufacturers including Watts, Zurn, and Wilkins, with specialty threading and flaring tools available for on-counter fabrication of non-standard pipe assemblies.
