Backflow testing is the annual check that keeps contaminated water from sneaking back into your clean water supply — and in most Central Texas cities, it’s required by law. Michalek Plumbing provides certified backflow testing, repair, and prevention services for homes and small businesses throughout Williamson County, Travis County, and the surrounding Hutto, Round Rock, Pflugerville, Georgetown, Cedar Park, Leander, and Austin areas.
If you have an irrigation system, a pool, a boiler feed, or any commercial connection to the municipal water supply, you almost certainly have a backflow prevention assembly — and it needs to be tested every year by a licensed backflow tester. We make compliance painless.
Key Takeaway
Backflow testing is a yearly inspection of your backflow prevention assembly to confirm it’s stopping contaminated water from flowing back into the public water supply. Most Texas water authorities require an annual backflow inspection on irrigation, pool, and commercial connections. Michalek Plumbing performs certified backflow testing, RPZ testing, repair, and replacement throughout Williamson and Travis Counties. Call (512) 759-2809 to schedule.
Understanding Backflow Testing: What It Is and Why It Matters
Backflow testing is one of those annual requirements that’s easy to overlook — until your city sends a reminder. The good news is that staying compliant is simple when you have a certified tester who knows the process.
Backflow happens when a drop or reversal in water pressure causes water to flow in the wrong direction through your plumbing system. A properly functioning backflow prevention assembly stops this from happening. Annual testing simply confirms your assembly is still doing its job — protecting both your property and the public water supply.
You may need a backflow inspection if:
- Your city or water utility sent you a testing notice
- You have an irrigation system, pool, boiler, or commercial water connection
- Your backflow preventer is leaking or showing signs of wear
- It’s been over 12 months since your last test

Quick clarification homeowners often ask about: a backflow preventer stops contaminated water from flowing back into the main water supply (typically installed at irrigation valves, pool equipment, and feed lines), while a pressure reducing valve reduces incoming city water pressure to a safer level for your fixtures and appliances (typically installed after the main shut-off on the homeowner’s side). Many Central Texas homes need both, and we install or service either.

Frequently Asked Questions
What is the main purpose of a backflow preventer device?
A backflow preventer stops contaminated water — from irrigation, pools, boilers, or chemical feed lines — from being pulled back into the clean potable water supply during a pressure drop or reversal. It protects your household and the broader municipal water system.
How often do I need backflow testing?
Most Texas water authorities require an annual backflow inspection on irrigation, pool, fire, and commercial assemblies. New installations typically require testing immediately upon activation. We can verify your city’s exact requirement when you call.
How much does backflow testing cost?
Backflow testing cost depends on the type of assembly (RPZ, DCVA, PVB), how many devices you have, and accessibility. Residential single-assembly tests are typically very affordable. We provide a clear price before scheduling.
What happens if my backflow assembly fails the test?
We walk you through exactly what failed and quote the repair or replacement on the spot. In many cases, we can repair the backflow preventer the same day, retest, and submit the passing report to your water authority for you.
Where is a backflow preventer installed?
Backflow preventers are typically installed at irrigation valves, pool equipment, boilers, and commercial feed lines — anywhere there’s a cross-connection between your plumbing and the municipal supply.
What’s the difference between a backflow preventer and a pressure reducing valve?
A backflow preventer stops contaminated water from flowing back into the main supply. A pressure reducing valve (PRV) lowers incoming city water pressure to a safer level for your fixtures and appliances. They solve different problems, and many Central Texas homes benefit from both.
Do you offer commercial backflow testing?
Yes — alongside our light commercial plumbing services, we handle RPZ backflow testing, DCVA testing, and full annual compliance for retail, office, restaurant, and small commercial buildings throughout Williamson and Travis Counties.
