About Diamond Plumbing & Pressure Washing in San Diego, CA

San Diego's hard water leads to rapid sediment buildup in water heaters, reducing efficiency and lifespan. Our expert water heater service includes thorough flushing to remove sediment, repair of corroded components, and professional installation of new, efficient models with built-in sediment management. Regular maintenance from our team can significantly extend your heater's life and lower energy bills.

We specialize in updating and repairing San Diego's older plumbing systems. Our services include comprehensive plumbing inspections to identify weak points, trenchless sewer repair to fix lines without major excavation, and complete repiping with durable materials. We also repair and replace aging fixtures like faucets, showers, and toilets to prevent leaks and improve water pressure in your home.

For tough clogs in older pipes, we recommend our professional hydro-jetting service. Unlike basic snaking, hydro-jetting uses high-pressure water to blast away years of accumulated grease, mineral scale, and debris—common in San Diego's aging drains—without damaging the pipes. This is often the most effective, long-term solution for recurrent drain problems and is part of our comprehensive drain repair and installation services.
