A backflow preventer is the assembly that stops contaminated water from flowing backward into the clean public supply — from an irrigation system, a boiler, or a commercial process line. Because a failed preventer can let fertilizer, chemicals, or dirty water siphon into your drinking water, most Texas water suppliers require these assemblies to be tested every year by a certified tester, with the results filed with the utility.
We handle the whole thing for Cibolo-area irrigation systems, commercial buildings, and multi-family properties: we test the assembly with calibrated gauges, make any repairs it needs, and submit the signed report to your water provider so you stay compliant. If you've gotten a notice from your water utility that your annual test is due, that's exactly what this service is for — and we make it painless.
When you need backflow testing
- You received an annual backflow-test notice from your water utility
- You're installing or just installed a new irrigation (sprinkler) system
- You run a commercial kitchen, medical office, or building with a required assembly
- Your assembly failed its last test and needs repair plus a retest
- You're buying or selling a property with a backflow device that needs certification
- You're not sure whether your system even has a compliant preventer
What's Included When You Book Backflow Testing
Every backflow testing & prevention job in Cibolo comes with the same standard of care — no vague “we'll take a look” and a surprise bill. Here's exactly what you get:
- Testing of your backflow assembly with a calibrated, up-to-date test kit
- Correct identification of the assembly type and size (RPZ, double-check, PVB)
- A signed, certified test report completed to your water supplier's format
- Submission of the report to your water utility so your compliance is on file
- Same-visit repair or rebuild and retest if the assembly fails
- A plain-English explanation of what the device does and why it's required
How backflow testing works
- 1
Locate & identify the assembly
We find your backflow preventer and confirm the type (RPZ, double-check, PVB) and size so the test is done to spec.
- 2
Test with calibrated gauges
We run the required test procedure on the assembly's check valves and relief valve using a calibrated test kit.
- 3
Repair if it fails
If a valve or seal has failed, we rebuild or replace the needed parts and retest — so you leave with a passing assembly, not just a failing report.
- 4
File the report
We complete the certified test report and submit it to your water supplier, so your compliance is on record with no chasing on your end.
What Affects the Price
Backflow testing is priced per assembly, with repairs quoted separately only if the device fails; we tell you the test fee up front.
- Number and size of assemblies being tested
- Assembly type (RPZ typically takes longer than a double-check)
- Whether repairs or a rebuild kit are needed after the test
- Residential irrigation vs. commercial or multi-family property
- Any re-test required after a repair

Backflow Testing FAQs
In most Texas water-supplier jurisdictions, testable backflow assemblies must be tested annually by a certified tester, with the report filed with the utility. Your water provider sets the exact schedule and usually mails a notice when your test is due. If you have an irrigation system or a commercial assembly, an annual test is the norm.
A failed test means a check valve or the relief valve isn't holding. We can usually rebuild the assembly with the correct repair kit or replace the failed part and retest on the same visit, so you end up with a passing, compliant device. We quote any repair before doing it — there's no surprise.
Yes. An irrigation system is a classic cross-connection risk — without a preventer, fertilizer, pesticide, or standing water in the lines can siphon back toward the drinking supply when pressure drops. Texas code requires a preventer on irrigation systems, and your water supplier requires it to be tested. We install, test, and certify them.
Yes, and we do it as part of the job. After a passing test we complete the certified report and submit it to your water supplier, so your compliance is on record. You don't have to track down forms or deadlines — we handle the paperwork.
A single residential irrigation assembly usually takes well under an hour — often 20–30 minutes to set up, run the test, and record the results. Multiple assemblies or a commercial RPZ take longer. We handle the report submission afterward, so your part is just giving us access to the device.
We test and repair the common testable assemblies — reduced-pressure zone (RPZ), double-check valve assemblies, and pressure vacuum breakers (PVB) — on residential irrigation systems, commercial buildings, and multi-family properties. If you're not sure what you have, we'll identify it when we arrive.
