Backflow Repair & Replacement Across Southern California

Protecting the public water supply is a critical responsibility for homeowners and businesses alike. A backflow preventer is a safety device on your plumbing system that stops contaminated water from flowing backward into the clean water supply.

At Drain Charmer Plumbing & Rooter Inc., our certified technicians specialize in the testing, repair, and installation of backflow devices.

Many local water authorities require annual testing of backflow prevention devices, especially for commercial properties and homes with irrigation systems, to ensure they are functioning correctly. A failed test can lead to fines and even a disruption of your water service. Our team is certified to perform these tests and handle all the necessary repairs and paperwork.

All of Our Backflow Services

We are certified to handle all aspects of your backflow prevention needs to keep your property safe and compliant. Our services include:

Annual Backflow Testing & Certification: Performing the required annual tests and submitting all necessary paperwork to your local water authority.
Backflow Preventer Repair: Repairing failed devices by replacing worn-out seals, springs, and other internal components.
New Backflow Device Installation: Installing the correct type of backflow preventer for new construction, irrigation systems, or commercial properties.
Backflow Device Replacement: Replacing old, failing, or non-compliant devices with modern, approved models.

If your backflow device fails its annual test, a repair is often needed to bring it back into compliance. Our technicians are experienced in servicing all types and sizes of backflow preventers, from the simple ones found on sprinkler systems to the large, complex devices used in commercial buildings.

Don’t risk the safety of your water supply or fall out of compliance with local regulations.

Andrew at Drain Charmmer and Rooter was super helpful, timely and attentive helping solve my tankless water heater issues. No hot water at the home front is an issue and resolving it quickly is three thumbs up. Many thanks!

Jimmie Culver

Drain Charmer and technicians are top notch. Ramon was able to fix my water heater in 5 minutes. Consider me a customer for life! Drain Charmer and Andrew replaced my water heater a few weeks ago and I couldn't be more pleased with the professionalism the entire crew displayed. Not only did they save me money but did the job 24 hours after I first called them. They truly are a 5 star company!

Drain Charmer did an excellent job replumbing our duplex that we are preparing to sell He and his team are very professional and great to work with. They reacted quickly to our urgent needs, provided an estimate same day, showed up on time and worked around the clock to complete the work fast. We are very impressed. Thank you Andrew and Jesse. Fun people to talk to.

A few days ago Andrew replaced my water heater the same day I called to announce the leak. The next day I texted him with questions about how to maintain the heater so it lasts longer. He spent 2 hours texting back and forth with me explaining how to do the yearly flush-out of both my units. I didn’t know how to do anything so it took sending photos in which Andrew patiently circled the knobs I needed to find and explained exactly how to do it. He is the best plumber I’ve found. I’ve used him for many jobs in the past and will continue to call on Andrew for my plumbing problems.

We had a weekend plumbing leak and the crew at Drain Charmer were so helpful, caring, and truly professional in fixing our issue. They went way beyond good service and we wouldn’t hesitate to call them with any future plumbing needs. We couldn’t be more pleased.

Wiktoria Marroquin

We had a plumbing emergency early on a Sunday morning, and while every other company told us we’d have to wait until the next day, Andrew and his team came through when we needed them most. They arrived within an hour! The customer service was outstanding from the start. Our technician, Jesse, was prompt, called ahead with his ETA, and resolved the issue quickly and professionally. Truly top-notch service — highly recommend them to anyone in need of fast, reliable, and friendly plumbing help.
