Your Plumbing Company in San Jose, CA
San Jose sits on clay-rich soil that swells in wet winters and shrinks through dry summers. That movement slowly shifts underground pipes, opening joints and creating low spots where waste collects. Add very hard groundwater in many valley-floor neighborhoods and an aging housing stock, and the result is the pattern we see across San Jose: recurring drain clogs, sewer backups, low water pressure, and water heaters that give out early.
As a plumbing company based in San Jose, we approach every job by finding the cause first. We camera-inspect sewer lines before recommending repair, and we explain the difference between a quick clear and a lasting fix so you can decide.

Plumber in San Jose, CA: FAQs
Answers to what San Jose homeowners ask us most.
Do you offer 24 hour emergency plumbing in San Jose?
Yes. California Plumbing Pros is available 24/7 for urgent plumbing in San Jose, including burst pipes, sewer backups, flooding, and no hot water. Call (800) 390-6351 any time.
Is San Jose water hard?
Much of the valley floor is served by groundwater that is very hard, while imported surface water is softer. That means many San Jose homes see mineral scale build up in pipes, fixtures, and water heaters over time.
Why does my San Jose sewer keep backing up?
San Jose sits on clay-rich soil that swells and shrinks, shifting underground lines out of alignment. Combined with tree root intrusion into older clay and cast iron laterals, that creates low spots and recurring backups. A camera inspection confirms the cause. See sewer line repair.
Do I need a permit to replace a water heater in San Jose?
San Jose generally requires permits for water heater replacements and major plumbing work. We can walk you through the scope of the project and what to expect during the process. See water heater replacement.
Do you offer commercial plumbing in San Jose?
Yes. Along with residential plumbing, we serve small businesses with drain, sewer, water heater, and leak services.
How do I know if my San Jose home needs repiping?
Signs include rusty or discolored water, low pressure throughout the home, frequent leaks, and noisy pipes. Homes with older galvanized or polybutylene piping are the most common candidates. See our repiping page for details.
