TCEQ-Certified Backflow Prevention in San Antonio, TX

Backflow Prevention

Backflow preventor repair, replacement, and annual certification — TCEQ License BPO025263.

Protect Your Water. Stay Compliant. Done Right.

Backflow is a serious plumbing issue that can contaminate your home's drinking water — or even the municipal water supply — when pressure drops in the system and water reverses direction through sprinkler heads, hose bibs, or commercial process equipment. That's why SAWS and most Texas municipalities require annual backflow preventer testing and certification.

MC 1 Plumbing holds TCEQ license BPO025263 — the Texas Commission on Environmental Quality Backflow Prevention Operator certification. We install, repair, replace, and annually certify backflow devices for residential, commercial, and irrigation systems throughout San Antonio.

Every Backflow Service, Done to Code

Backflow is a regulated plumbing specialty that requires TCEQ certification. Here's what MC 1 handles with our BPO025263 license.

📋

Annual Certification Testing

SAWS and most Texas water authorities require annual testing of backflow preventers. MC 1 performs the test, files the required paperwork, and keeps you compliant year over year.

🛡️

New Device Installation

New construction, remodels, or adding irrigation — backflow devices must be installed to TCEQ standards. We handle installation correctly the first time.

🔧

Repair & Rebuild

Failed tests don't always mean replacement. Many backflow preventers can be rebuilt with new internals and pass certification. We diagnose whether rebuild or replace is the right call.

🔄

Device Replacement

When repair isn't cost-effective or the device is beyond saving, we replace it with the appropriate TCEQ-approved backflow preventer for your application.

💧

Irrigation Backflow

Most San Antonio homes with irrigation systems require backflow protection. We install and certify irrigation backflow devices to keep your drinking water safe from sprinkler contamination.

🏢

Commercial Compliance

Commercial properties often have multiple backflow devices with different testing requirements. We handle full-property backflow programs for property managers and commercial clients.

Signs Your Backflow Preventer Needs Service

Backflow preventers are mechanical devices that wear out. Don't wait for SAWS to send you a notice — catch these warning signs and handle testing proactively.

Annual test notice received from SAWS or water authority
Visible damage from freeze, impact, or corrosion
Water leaking from the relief vent port
Failed previous test requiring retest or repair
No record of testing in the past 12 months
New irrigation system needs backflow installation
Property transfer requiring compliance verification
Missing device tags or documentation gaps

TCEQ Certified — The Right License for the Job

Not every plumber can legally test and certify backflow devices in Texas. It requires the TCEQ Backflow Prevention Operator license — which MC 1 Plumbing holds under certification number BPO025263. When you hire us for backflow work, you're hiring a specialist who's completed the required training and maintains the certification.

We handle the test, file the paperwork with SAWS, and keep your property compliant. No guesswork, no compliance headaches — just the right license for the right job.
