Common Plumbing Problems in Ontario Homes

Plumbing in Ontario & San Bernardino County
High-desert parts of San Bernardino County get freezing winter nights, so exposed pipes and hose bibs need protection.
Water in the Inland Empire and desert communities tends to be hard, which shortens water heater life and clogs fixtures in Ontario homes. Summer heat in Ontario pushes water heaters, irrigation lines and cooling systems hard, and outdoor pipes see big temperature swings.
We serve every neighborhood in Ontario, from the town center to the outlying streets, plus the surrounding San Bernardino County area.
Nearby towns we serve: Guasti (2 mi), Montclair (5 mi), Rancho Cucamonga (5 mi), Chino (5 mi), Upland (6 mi), Claremont (6 mi), Mira Loma (7 mi), Pomona (8 mi).
