Backflow Preventer Repair

Backflow Preventer Repair: Restore Protection, Ensure Compliance, and Safeguard Water Quality

A backflow preventer is one of the most critical components of any plumbing system—designed to keep contaminated water from reversing into your clean water supply. But when this vital device fails, your entire property is at risk. At Blackmon Plumbing, we offer expert backflow preventer repair services across Houston, The Woodlands, and surrounding North Houston communities. Whether your device is leaking, failing inspection, or simply worn out, our certified technicians restore it to peak performance quickly and affordably.

What Causes Backflow Preventer Failure?

Like any mechanical component, backflow preventers are subject to wear and tear over time. Exposure to debris, corrosion, extreme temperatures, and fluctuating water pressure can cause:

Leaking test ports or check valves

Cracked bodies from freezing

Malfunctioning shutoff valves

Stuck or weakened internal springs

Sediment buildup obstructing flow

Failing to address these issues not only risks contamination but can also lead to failed annual inspections, code violations, and water utility shut-offs.

Signs You May Need Backflow Preventer Repair

It’s not always obvious when a backflow preventer begins to fail. However, you should schedule service if you notice:

Visible leaks or dripping from the device

Low water pressure in the building

Water flowing continuously through relief ports

Unusual water discoloration or odor

Failed backflow test results

Inspection violations from city or HOA

Our skilled team at Blackmon Plumbing conducts thorough diagnostics to pinpoint the exact failure and perform repairs that meet or exceed local regulations.

Backflow Preventer Repair vs. Replacement

In some cases, repair may not be the most cost-effective solution. If your device is:

Over 10–15 years old

Badly corroded or cracked

Lacking replacement parts

Outdated and no longer code-compliant

…our team may recommend a full replacement. We’ll provide an honest assessment, explain your options, and guide you through the process with clear pricing and no-pressure advice.
