What Our Business Clients Say About Us in San Jose

Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.
Ron K.

Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!
Allan Huynh

CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

San Jose Commercial Plumbing FAQs

What is Commercial Plumbing?
Commercial plumbing refers to the installation, repair, and maintenance of plumbing systems in non-residential buildings such as offices, retail spaces, medical facilities, and multi-tenant properties. Unlike residential plumbing, it must account for larger water usage, complex pipe networks, multiple fixtures, and stricter code compliance. At CPI Services, we specialize exclusively in commercial plumbing solutions tailored to San Jose businesses, ensuring both functionality and regulatory alignment.
How much does Commercial Plumbing cost?
Costs for commercial plumbing in San Jose can vary based on project size, system complexity, and materials used. Small repairs (like faucet or valve fixes) may start around $150–$300, while larger jobs (such as repiping or commercial water heater installations) can range from $2,000 to $15,000+. CPI Services provides clear, written estimates upfront, no hidden charges, just reliable, transparent pricing.
How often should commercial plumbing systems be inspected?
For optimal performance and code compliance, CPI recommends a full system inspection at least once per year. High-use properties like restaurants, schools, or medical facilities may require biannual inspections to prevent backups, leaks, or contamination risks. Regular inspections help identify minor issues early, saving San Jose businesses from major repair costs down the line.
Are there specific plumbing codes for commercial properties in San Jose?
Yes. All commercial plumbing work in San Jose must comply with the California Plumbing Code and local city amendments. These codes dictate pipe sizing, material types, fixture installations, and water conservation requirements. As a CSLB-licensed contractor, CPI ensures that all work we perform meets or exceeds these standards. We handle permits, inspections, and compliance reviews on your behalf.
What are common signs of a plumbing leak in a commercial property?
Typical signs of plumbing leaks include unexplained spikes in water bills, mold growth, musty odors, visible wall stains, and low water pressure. Commercial buildings in San Jose may also experience slab leaks or underground pipe failures, which can be harder to detect. CPI Services uses non-invasive thermal and acoustic leak detection tools to pinpoint problems before they escalate into costly structural damage.
