If your backflow device fails inspection or malfunctions, we offer fast, expert repairs. Our licensed specialists can diagnose issues and restore proper operation, helping you avoid fines, water contamination, and costly system failures.

We install and replace devices for new construction projects, system upgrades, and compliance retrofits. We offer emergency services for leaks or theft and can install security cages to prevent future issues.

What is Backflow and Why is Prevention Important?

Backflow happens when contaminated water flows backward into the clean water supply, posing serious health risks. San Diego requires backflow prevention devices on irrigation systems, commercial properties, and buildings with potential cross-connections.

Annual testing and maintenance are critical to ensure these devices work properly — and to protect your family, employees, or customers from harm.

At 1 Affordable Backflow, we make prevention easy and stress-free.

What Our Customers Have to Say

Dan Jones
Customer

We needed a backflow installed and called multiple companies. Alfredo and his team were competitive in their pricing, prompt, and very communicative. We're thrilled with our experience as they guided us through the process and helped us work with the water district to ensure the backflow was installed properly. Thank you 1 Affordable Backflow!

Great service on our annual backflow inspection! Very easy to work with, perfect communication, and fast inspections too! Alfredo provides excellent customer interaction - much better company to work with than our previous provider! Richard, Rancho San Diego, CA

Marley Williams
Customer

Alfredo was contacted by our neighbor while we were out of town when, on a walk, he saw that the pipe from the street to our backflow had broken and recognized 1Affordable’s tag on our backflow. Alfredo immediately drove out to turn off the water, sent us pictures and provided an estimate to repair the pipe, saving us hundreds on our water bill. We’ve been clients for 7 years and will continue to be loyal to Alfredo and 1Affordable
