San Marino is one of the most regulated cities in Los Angeles County. And when it comes to plumbing, the bar is high. Permits, inspections, and tight work windows are all part of the job, even for routine repairs.
At Ritz Plumbing, every job is done correctly and up to code. With decades of experience serving San Marino homes and businesses, we deliver licensed, inspection-ready service—whether you’re clearing a blocked line, replacing a water heater, or building out plumbing for a new Accessory Dwelling Unit (ADU).
Homeowners, property managers, and business owners depend on our plumbing services in San Marino, including neighborhoods near Lacy Park, Huntington Drive, San Gabriel Boulevard, and Virginia Road.
Your home deserves white-glove plumbing service in San Marino. Whether you live in a historic estate or a newly built ADU, Ritz Plumbing delivers high-end workmanship.
Our team handles everything from urgent repairs to full-system builds with careful planning, spotless installs, and flawless code compliance, that pass inspection the first time and protect the beauty of your home.
Our plumbing services include:
We install and repair water lines, fixtures, and drainage systems in kitchens, bathrooms, laundry rooms, garages, and basements. Every job is code-compliant and built to last, from small leak fixes in a single-family home to full-system upgrades in estate properties or storefronts.
In San Marino, ADUs must integrate seamlessly with your property’s existing systems—there’s no room for error. Our qualified plumbers provide ADU plumbing installations, handling everything from main line connections and pressure balancing to cleanouts and venting.
Every detail is designed for easy inspection, long-term performance, and the high standards your property deserves.
Blocked drains can damage your property if not handled properly. Our skilled technicians use commercial-grade hydro jetting and auger equipment to clear tough clogs caused by roots, grease, or debris.
We provide video inspections for persistent issues or hidden blockages. These help identify line breaks, slope failures, or obstructions beneath driveways, lawns, or foundations without unnecessary digging.
When your water heater shows signs of age, performance issues, or leaks, precision matters. We handle expert repair and replacement of gas and electric units—both tank and tankless.
Every installation includes proper venting, expansion tanks, shutoffs, and gas line sizing—carefully tailored to meet San Marino’s strict code requirements and your home’s plumbing demands.
A properly installed backwater valve is essential for homes below street level or with basement fixtures. Our licensed professionals install and upgrade backwater valves to prevent sewer backups during storms or blockages. Each system includes clearly labeled, code-compliant cleanouts to ensure smooth inspections and lasting protection.
We use advanced camera diagnostics to locate sewer line damage before a shovel hits the ground. When repairs or full reconnects are needed, our team uses trenchless methods whenever possible to preserve driveways, stonework, and mature landscaping that define many San Marino homes.
Gas line work requires precision and code expertise, from outdoor grill lines to kitchen upgrades. Whether adding a new appliance or rerouting existing lines, we install and pressure-test gas piping with careful attention to appliance specs, meter capacity, and all city-mandated testing protocols.
No matter the size or scope, every installation is tailored to meet San Marino’s strict standards, ensuring safety, reliability, and seamless inspection approval.
In San Marino, meeting California plumbing code is just the beginning. Every project must also comply with city-specific amendments that govern everything from backflow prevention to cleanout placement, adding an extra layer of precision to every installation and repair.

This level of code familiarity helps avoid red tags, failed inspections, and costly delays, especially on permitted work in older or expanded homes.
