Backflow Preventer Testing

Backflow Preventer Testing: Protecting Houston’s Water Supply with Certified Precision

A properly functioning backflow preventer is your first line of defense against contaminated water entering the public water supply. At Blackmon Plumbing, we specialize in certified backflow preventer testing for both residential and commercial systems across Houston, The Woodlands, and North Houston communities. With annual testing required by most local municipalities, it’s essential to work with licensed professionals who understand every component of your system and deliver fast, compliant results.

What Causes Backflow Preventer Failure?

A backflow preventer is a mechanical valve assembly that ensures water flows in one direction—into your home or business. If water pressure drops or reverses due to a break, surge, or back-siphonage, the device prevents dirty or hazardous water from contaminating your clean water supply.

Over time, internal components can wear down or malfunction. That’s why most Texas cities and utility districts require annual backflow preventer testing to confirm your device works as intended.

Without annual testing, you risk:

Failing a plumbing or irrigation inspection

Water service interruption from city utilities

Health hazards from cross-contamination

Fines or compliance penalties

Who Needs Backflow Preventer Testing?

The short answer? Almost everyone. Texas water districts and municipalities require annual backflow testing for:

Residential irrigation systems

Commercial properties

Restaurants and food prep facilities

Medical clinics and dental offices

Fire suppression and sprinkler systems

Apartment buildings and condos

Boiler systems and cooling towers

If your property has a cross-connection to the public water system, you’re responsible for maintaining and certifying your device yearly.

What Happens During a Backflow Test?

During a backflow preventer test, we follow a thorough multi-step procedure:

Shut off downstream water supply

Connect test kit gauges to the backflow assembly

Monitor pressure zones to ensure valves are holding proper pressure

Check for leaking or failed components

Document performance against TCEQ standards

Tag the device with a testing date and certification

Submit documentation to the local water authority

If the device fails, we’ll provide an immediate quote for repairs or replacement and offer to retest after correction.

Signs Your Backflow Device Needs Immediate Testing

Even if you’re not due for an annual test, your backflow preventer might require attention if you notice:

Leaking from valve bodies or relief ports

Unexplained drops in water pressure

Discoloration or odor in water supply

Property damage from internal leaks

City-issued reminder or warning notice

We recommend testing after any major plumbing service, line break, or irrigation repair.
