- Financing Available for Larger Installations: Water heater replacements and system upgrades are manageable with flexible payment options through Service Finance Company — no need to delay the job over upfront cost.
- Diagnostic Fee Waived Upon Repair: Schedule a diagnostic and move forward with the repair. The diagnostic fee gets applied toward the total cost of the job.

- All Major Brands Serviced: Crown Plumbing installs and services all major water heater brands — Rheem, Bradford White, Rinnai, Navien, A.O. Smith, State Water Heaters, and more. Whether the unit is gas, electric, or tankless, the technician arriving at your door knows the system.

Our commercial & industrial plumbing services in San Jose, CA, cover every system your facility relies on — from water supply and drainage to renovations and beyond.

We evaluate:
- Water pressure across multiple fixtures during active use

This allows for accurate planning before repair or cleaning.
How Your Bathroom Remodel Comes Together
Sewer Drain and Pipe Cleaning
Commercial drain systems must handle constant use.
We provide sewer drain cleaning and pipe cleaning services that:
- Clear blockages affecting system performance
- Evaluate the branch and main lines

Hydro Jetting Services
For heavy buildup, hydro jetting provides a deeper solution than standard cleaning.
We:

This is critical for restaurants, high-use facilities, and industrial plumbing systems.

We:

- Restore system integrity quickly
Water Heater and Boiler Installation
Commercial facilities run on consistent hot water demand — a system sized for residential use won’t cut it.

- Install filtration systems and water softeners that protect equipment and extend fixture life
- Maintain pressure and flow efficiency throughout
- Improve water quality across every point of use in your facility

Common Commercial & Industrial Plumbing Problems We Solve
Commercial and industrial plumbing systems carry a heavier load, run longer hours, and leave far less room for error than most property owners realize.
Corroded Pipes
Years of high-volume water flow accelerate corrosion in commercial systems far faster than in residential ones. Corroded pipes restrict flow, compromise water quality, and weaken joints until a small leak becomes a facility-wide problem. Our team inspects, replaces, and repairs affected pipelines before the damage compounds.
Leaking Pipes
Water migrates behind walls, above ceilings, and beneath slabs, quietly driving up utility bills and softening structural materials. Our licensed plumbers locate and repair leaking pipes with minimal disruption to your active facility.
Sewer Backups and Blockages
A sewer backup in a commercial or industrial setting affects multiple fixtures, multiple floors, and, in some cases, the entire building. We respond same-day, clear the blockage, and inspect the sewer line to determine whether a sewer line repair is needed to prevent recurrence.
Gas Leaks and Gas Line Issues
A gas leak in a commercial or industrial facility demands immediate action. Delayed response puts staff, customers, and the entire property at risk. Our licensed plumbers locate and repair gas line failures fast, restore safe operating pressure, and inspect the full gas line system to confirm no secondary issues remain.
Aging Plumbing Systems
Older commercial systems were built for a different era of demand. Outdated pipes, undersized supply lines, and deteriorating drain fields create compounding inefficiencies. Our team handles everything from targeted upgrades to full repiping and septic drain field repair.
Pipe Pressure and Flow Issues
Inconsistent pressure across a commercial facility points to blockages, pipe deterioration, or supply line failures. We diagnose the root cause and restore consistent flow, including water line repair and replacement where the supply infrastructure needs attention.
Industries We Serve
Every commercial sector runs its plumbing infrastructure differently, and a one-size-fits-all approach leads to shortcuts. Crown Plumbing tailors every service to the specific demands of your environment.

Frequently Asked Questions
What makes commercial plumbing different from standard plumbing work?
Commercial plumbing must account for larger water usage, complex pipe networks, multiple fixtures, and stricter code compliance. Systems in commercial and industrial facilities also run longer hours under heavier demand, which means failures carry higher stakes and require faster resolution.
Does commercial plumbing work require permits in San Jose?
Commercial plumbing projects in San Jose are subject to city regulations, and permits affect both timing and scope. Any work involving plumbing system modifications, new installations, or structural changes typically requires city approval. Contact Crown Plumbing directly to confirm what your specific project requires before scheduling.
How often should a commercial facility schedule plumbing maintenance?
Regular inspections, preventive maintenance, and ongoing system optimization keep commercial plumbing running efficiently and reduce the likelihood of costly repairs down the line. The right maintenance schedule depends on your facility type, usage volume, and the age of your existing infrastructure.
How quickly can Crown Plumbing respond to a commercial plumbing emergency?
Crown Plumbing operates 24/7, and dispatches licensed plumbers the same day for commercial and industrial emergencies across San Jose. Every call gets answered regardless of the hour, and every job starts with a written estimate before work begins.
