Why Choose Homewerx?

California Law Requires Testing

San Diego requires annual backflow preventer testing by a certified tester. Expired certifications result in water service disconnection notices — we keep you compliant year-round.

Cross-Connections Contaminate Drinking Water

Without functioning backflow prevention, irrigation chemicals, pool water, or boiler fluid can siphon back into your drinking supply during pressure drops. The health risk is real and preventable.

Irrigation Systems Are High Risk

Every irrigation system connected to potable water needs a backflow preventer. Fertilizer, pesticide, and soil bacteria can contaminate your household water through an unprotected irrigation connection.

Failed Tests Mean Failed Devices

When a backflow preventer fails its annual test, internal components have worn out. Rebuilding or replacing the device promptly prevents the water district from shutting off your service.

Our Process

01

Risk Assessment

We identify every cross-connection on your property — irrigation, pool fill lines, boiler connections, hose bibs — and determine which backflow protection each requires.

02

Device Selection

We match the correct backflow preventer type to each application — reduced pressure zone assemblies for high-hazard connections, double check valves for lower-risk points.

03

Installation

Professional installation with proper clearances, orientation, and test ports. We ensure the device is accessible for annual testing and positioned to drain safely.

04

Initial Testing & Certification

Every new installation is tested immediately using calibrated test equipment. We file the certification with the San Diego water authority on your behalf.

05

Annual Testing Service

We track your annual testing deadline and schedule your appointment proactively. Test, certify, and file — no compliance gaps, no disconnection notices.

06

Repair & Rebuild

When devices fail testing, we rebuild or replace internal components on-site. Most repairs are completed the same day as the failed test, restoring compliance immediately.
