Backflow Testing & Repair in Las Vegas

Backflow Testing & Prevention by Desert Peak Plumbing Solutions in Las Vegas, NV

A backflow preventer keeps irrigation water, fire sprinkler water and process water from being pulled back into the public drinking water supply. In Southern Nevada, testable backflow assemblies on commercial properties, HOA irrigation, fire lines and many residential irrigation systems must be tested every year, and the results reported to the water purveyor.

Desert Peak Plumbing Solutions tests, repairs and installs reduced pressure zone (RPZ), double check valve (DCVA) and pressure vacuum breaker (PVB) assemblies. We handle the paperwork, keep a record of your test dates and remind you before the next one is due.

Extra Advantages of Our Service

Backflow assemblies in the desert sun need more than an annual test to stay reliable.

A typical visit looks like this: we confirm the assembly type and serial number, record line pressure, run the test sequence for each check valve and the relief valve, and note the results on the purveyor's form. If the assembly passes, you get a copy of the report the same day. If it fails, we explain the failed component, quote the rebuild and, with your approval, complete and retest it during the same visit whenever parts are on the truck.

What Our Service Covers

During a test we connect a calibrated gauge to the test cocks and check each check valve and relief valve against its required pressure differential. If the assembly passes, the report is filed. If it fails, we explain which part failed and quote the repair on the spot.

Most single-assembly tests take under an hour, and water is only off for a few minutes while the test is performed. See a recent example: Enterprise Retail Center Backflow Testing.

Water purveyors in Southern Nevada track every testable assembly in their service areas and send notices when a test is due. Missing the deadline can lead to follow-up letters and, eventually, interruption of water service. We schedule tests ahead of your due date, file the results and keep a record of each device, so property managers do not have to chase paperwork every year.

Frequently Asked Questions

Answers to the questions Las Vegas customers ask us most about backflow testing & prevention. Have a different question? Call (702) 555-0148.

Testable assemblies must be tested at least once a year, and also after installation, repair or relocation. Your water purveyor sends a notice when the test is due.

We identify the failed component, usually a check valve or relief valve seal, and rebuild the assembly. After the repair we retest and file the passing result.

Homes with testable assemblies on irrigation systems, pools or fire sprinklers usually do. Check your water bill or district notice, or call us to look at your setup.

Yes. We install the correct assembly for the hazard, test it after installation and file the initial report.

Pricing depends on the number and size of assemblies on the property. Multiple devices tested on the same visit cost less per device. Repairs, if needed, are quoted after the test.

A reduced pressure zone assembly may discharge water from its relief valve when pressure fluctuates or when a check valve is fouled. Constant dripping means the assembly needs service.
