Frequently Asked Questions

Backflow Prevention Basics

What is backflow and why is it a concern?

Water normally flows one way through pipes. When it reverses, it can pull contaminants into drinking water, creating health hazards.

Why do fire sprinkler systems need backflow preventers?

Fire systems contain stagnant water that can become contaminated. Without prevention, this water could flow back into clean water during pressure changes.

Are backflow preventers required by code?

Yes. Houston requires approved backflow devices on all commercial fire sprinkler systems and certain plumbing systems.

What happens if my backflow preventer fails a test?

Failed devices must be repaired or replaced immediately. We can usually make repairs on the spot, but sometimes replacement is necessary. We’ll explain your options.

Testing Requirements

How often do backflow preventers need testing?

Annual testing is required for all commercial backflow preventers. Some high-hazard installations may require more frequent testing.

What does a backflow test involve?

We check all components, measure pressure differentials, and verify valve operation. The process takes 30-60 minutes per device.

Who can perform backflow preventer testing in Houston?

Only TCEQ-certified backflow testers can perform and certify tests. Our technicians maintain current certifications.

What documentation will I receive after testing?

You’ll get a test report showing pass/fail status and any repairs made. We submit copies to authorities and provide documentation for your records.

Installation & Maintenance

Where should backflow preventers be installed?

At the point where fire lines connect to water main, before any branches. They need proper clearances for testing and maintenance.

Do backflow preventers affect water pressure in my fire system?

Yes, they create some pressure loss. Proper system design accounts for this to ensure adequate fire protection pressure.

How long do backflow preventers last?

With proper maintenance, 15-20 years. Regular testing identifies wear before problems develop.

What maintenance do backflow preventers require?

Beyond annual testing, occasional cleaning and inspection. Rebuilding internal parts every 5 years extends service life.

Common Issues

Why would water discharge from my backflow preventer?

Relief valve discharge shows the device is working to prevent backflow. Continuous discharge means repairs are needed.

Do backflow preventers freeze in cold weather?

Yes, outdoor units need freeze protection in Houston’s cold snaps. We provide insulated enclosures or heating options.

Can backflow preventers cause water hammer?

Yes, fast-closing valves can create pressure spikes. Proper installation includes expansion chambers when needed.

Are there different requirements for fire sprinkler backflow preventers versus domestic water?

Yes, fire system backflow requirements differ from those for plumbing systems. We understand both sets of regulations.
