A failed test usually comes down to dirt on a check valve or worn rubber parts. We tell you what failed and what it costs, fix it, test it again, and send the passing report to your district.

When to call for a repair
- Your last test didn't pass
- Water is spraying or dripping from the device
- Water pressure dropped after the device
- The district wants a passing report and you don't have one
If the body is cracked or the device is gone, you'll need a replacement instead.
What usually goes wrong
The causes behind most failed devices are predictable. Grit from the main gets stuck on a check seat. Rubber parts dry out and crack. Springs lose tension. RP relief valves develop torn diaphragms.
Each of these can be fixed with manufacturer parts. The failed test readings show us which part to open, which keeps repairs quick and affordable.
Cracked bodies from freezes or impacts are the exception. Those usually call for a new device, and we'll be upfront about it.
Know the price before we start
Every repair starts with a quote. After the test, we show you the reading that failed, explain what's likely causing it and give you the price for parts and labor. Nothing happens until you say yes.
Most repairs use a rebuild kit and take one to two hours, including the retest. If we need to order parts for an uncommon model, we'll tell you how long it'll take and schedule a return visit.
The retest after repair is included. So is filing the passing report with your water district. You won't get a separate bill for paperwork.
Leaks, theft and urgent failures
Some repairs can't wait for a regular appointment. A relief valve dumping water nonstop, a device cracked by a freeze or a stolen assembly leaving a pipe open all need attention right away.
Emergency calls are answered 24/7. Close the shutoff valves on the device, or the main at the meter, and call us. We'll give you a price on the phone and get someone out as quickly as possible.
The same goes for a failed test with a shutoff date coming up. Tell us the date and we'll prioritize the repair so the passing report is filed in time.
Repairs for homes and for businesses
At a home, repairs are usually on a sprinkler device and take an hour or two with the water off. Many are done right after the test, on the same visit.
Businesses need more planning. Fire line devices affect the sprinkler system, and water shutoffs can disrupt customers or patients. We schedule around your hours and keep downtime short.
After a failed test
When a device fails, the district needs a passing report after the repair. We record both the failed result and the passing retest, along with the parts replaced, and submit it.
If your district set a deadline, tell us. We'll make sure the repair and retest are done in time.
Parts we carry
Our trucks carry rebuild kits, springs, test cocks and common bonnets for the backflow devices we see most often across Riverside. That's why many repairs are done on the same visit as the test.
For less common models or larger fire line assemblies, we order manufacturer parts. Most arrive within a few days, and we'll schedule the return visit as soon as they're in.

Backflow Preventer Repair
We fix every common type of backflow preventer: RPs that dump water, double checks that fail, and vacuum breakers that leak. Parts match your exact model. You approve the price first, and the retest and district filing are included once the repair is done. Most repairs are finished in one to two hours. More about backflow preventer repair.
Backflow Assembly Repair
When an assembly fails its test, we use the readings to find the failed part, rebuild it with the manufacturer's parts and test it again on the spot. Water is usually off 30 to 60 minutes. The passing report goes to your district, and you approve the price before any work. More about backflow assembly repair.
Emergency Backflow Repair
Backflow device leaking, spraying, cracked or stolen? Emergency calls are answered 24/7. Close the shutoff valves or the main at the meter, then call. We'll get a tester moving, give you the price on the phone, repair or replace the device and file the report. Nights, weekends and holidays are all included. More about emergency backflow repair.
Questions
What happens if my device fails the test?
You'll hear exactly what failed and what the fix costs before we touch anything. Usually it's a cleaning or a rubber kit. Once it's fixed we test again and file the passing report. More on repairs.
Repair or replace: which one makes sense?
Repair, most of the time. A rebuild kit fixes the majority of failures. We'd only suggest a new one if the body is cracked, parts aren't available, it was stolen, or your property now needs a different type. More on replacement.
