Commercial Plumbing in San Diego County

Full-Service Commercial Plumbing for San Diego County Businesses

When a plumbing issue shuts down business operations, the cost isn’t just the repair. It’s lost revenue, frustrated tenants, and potential health code scrutiny. Plumbing Plus has been the commercial plumbing contractor San Diego County businesses rely on since 1984. We have more than 40 years of continuous operation under the same brand, built on straightforward work and honest pricing. Owners Michael and Rachael De Silva have led the company since 2010, and Michael came up through the trade himself, joining the team in 2001 and working up to lead plumber before taking ownership. This is a business run by people who know plumbing from the ground up.

We serve restaurants, office buildings, retail centers, apartment complexes, healthcare facilities, and property management clients throughout San Diego County. Whether you need routine drain service or an emergency response at 2 a.m., our red, white, and blue trucks are ready to show up and handle the job.

Commercial Plumbing Services We Provide

Commercial properties place demands on plumbing systems that residential work simply doesn’t match: higher daily usage, stricter code requirements, and the added pressure of keeping tenants, employees, and customers unaffected. We offer a full range of commercial plumbing services to cover every system in your facility.

Our commercial plumbing services include:

• Drain Cleaning and Hydro Jetting: High-pressure water clears buildup from commercial drain lines that standard snaking can’t fully reach. This is essential for high-volume kitchens and restrooms.
• Pipe Repair, Relining and Rerouting: Trenchless relining and full reroutes when structural pipe issues require more than a spot repair.
• Sewer Camera Inspection: Video diagnostics before any major repair decision, so you know exactly what you’re dealing with.
• Sewer Repair and Services: Full sewer line repair and maintenance for commercial properties.
• Leak Detection: Pinpoint identification of hidden leaks in supply and drain systems before they escalate.
• Water Line Services: Installation, replacement, repair, and maintenance of commercial water supply lines.
• Commercial Water Heater Installation and Maintenance: Full-capacity units installed and maintained to handle commercial demand.
• Backflow Prevention: Installation and service to protect potable water supplies in accordance with California Plumbing Code requirements.
• Fixture Installation and Repair: Restroom, kitchen, and utility fixtures replaced or repaired on your schedule.
• Gas Plumbing: Commercial gas line service and installation.
• Water Filtration and Treatment: System-level filtration for commercial facilities.
• Smart Water Shutoffs: Automated shutoff devices that help detect and limit water loss from unexpected failures.
• Grease Trap Service: Maintenance of grease interceptors for food service establishments to prevent FOG buildup and drain blockages.

We offer flexible appointment scheduling to work around your operating hours and minimize impact on staff and customers.

Commercial Plumbing Systems We Service

Every commercial facility has its own plumbing profile. We work across all major system types that businesses and property managers encounter.

Restroom Plumbing

High daily usage accelerates fixture wear and increases the frequency of stoppages. We handle everything from fixture replacements to supply line repairs, keeping restrooms operational without extended downtime.

Commercial Kitchen Plumbing

Fats, oils, and grease accumulate in kitchen drain lines faster than standard drain cleaning can keep pace with. We use hydro jetting to clear FOG buildup thoroughly, and we service grease trap interceptors that capture this material before it reaches the sewer system. Keeping interceptors maintained is both a health code requirement and practical protection against costly drain failures.

Water Heaters & Supply Lines

Commercial water heaters are sized and configured differently from residential units, and multi-story or multi-unit buildings depend on consistent pressure across all floors. We install and maintain commercial water heaters and address supply line integrity issues that affect pressure regulation throughout a building.

Drainage & Sewer Systems

Before recommending any major repair, we use sewer camera inspection to confirm exactly what’s happening inside the line. Hydro jetting clears what the inspection reveals. When structural repairs are needed, we handle pipe relining and full sewer repair to restore system function.

The Plumb Star Partner™ Membership Program

For commercial clients who want more than a call-when-something-breaks relationship, the Plumb Star Partner™ membership program provides a structured maintenance plan with priority access and meaningful cost advantages.

Plumb Star Partner™ members receive:

• Front-of-line priority scheduling for both routine and emergency calls
• 10% off all plumbing services
• No dispatch fees
• Free estimates
• One-year workmanship and materials warranty on all work completed while the plan is active

Annual Safety Inspection Included

Each membership year includes a comprehensive inspection covering: water quality test, water pressure check, leak inspection, dye testing of toilets, water meter check, water heater flush, and a sewer camera inspection of one drain.

For property managers overseeing multiple units, a predictable annual inspection schedule and priority emergency response can work together to reduce unplanned downtime and make maintenance budgets more manageable. This combination of benefits isn’t available outside the program.

Preventive Maintenance for Commercial Properties

Commercial plumbing issues rarely announce themselves before they cause disruption. Small leaks, mineral buildup, and worn components develop gradually, and routine inspection is the primary way to catch them before they turn into operational failures. Industry guidance generally recommends commercial systems be inspected at least twice annually, depending on facility type and usage intensity.

We offer preventive maintenance and long-term service agreements for commercial clients. Plumb Star Partner™ members receive a structured annual safety inspection as part of their membership. Even between scheduled visits, our emergency repairs team is available around the clock, so a developing problem doesn’t have to wait until business hours to get addressed.

Commercial Plumbing FAQs

Is Financing Available for Commercial Plumbing Work?

Yes. We’ve partnered with Service Finance to offer flexible financing options for commercial clients. Short-term plans with low interest and longer term plans with lower monthly payments are both available, so urgent repairs or larger system upgrades don’t have to wait on budget cycles.

What Signs Suggest My Commercial System Needs a Professional Inspection?

Repeated drain stoppages, inconsistent water pressure across floors, unexplained increases in water bills, and slow fixture drainage are all indicators that something deeper may be happening in the system. A sewer camera inspection can confirm what’s occurring inside the line before you commit to a repair approach.

We work with restaurants, office buildings, retail centers, apartment complexes, healthcare facilities, and property management clients throughout San Diego County. If your facility has plumbing, we can service it.
