What backflow testing and service covers
Backflow prevention assemblies must be tested under actual working conditions using a calibrated differential pressure test kit. A visual inspection alone does not satisfy the requirement — the assembly must be tested under water pressure with the results documented.
Our backflow services include:
- Certified differential pressure test of the backflow preventer assembly
- Test report documentation in the format required by Arvada Water
- Direct submission of test results to the utility
- Assembly repair or rebuild when testing reveals a failing check valve, seat, or relief valve
- Full assembly replacement when repair is not cost-effective
- Backflow preventer installation on new irrigation, commercial, or fire-line connections
- Annual reminders and scheduling so you never miss the testing window
- Irrigation system startup combined with annual backflow test
When you need backflow testing or a new assembly
Backflow requirements are triggered by specific types of connections and circumstances. These are the situations that put you in scope.
- You have an irrigation system connected to the potable water supply
- You received a compliance notice from Arvada Water or Jefferson County
- Your backflow test is due annually and last year's testing window has passed
- A test was conducted and the assembly failed — now repair is required
- You are adding a new irrigation connection, chemical injection point, or commercial water connection
- You have a commercial property with a reduced-pressure zone assembly
- A building permit for remodel or new construction includes a backflow requirement
- You are purchasing a property and the inspection revealed a missing or untested assembly
Why backflow prevention matters in Arvada
The risk is real and the requirement is not bureaucratic box-checking. These are the actual conditions that create backflow risk in residential and commercial settings.
Irrigation cross-connection
An irrigation system draws from the potable supply and discharges into soil that contains fertilizer, pesticide residues, and naturally occurring bacteria. If supply pressure drops — during a fire-flow test, a water main break, or peak demand — the pressure differential can pull that water backward through an unprotected connection into the drinking supply. The backflow preventer's job is to make that impossible. Colorado's requirement for annual testing exists because check valves and relief valves can fail without any visible sign.
Commercial and industrial cross-connections
Restaurants, car washes, medical offices, and industrial facilities all have non-potable water connections — cleaning chemicals, cooling systems, and process water — that require reduced-pressure zone (RPZ) assemblies. These are more complex than residential irrigation preventers and must be tested annually by a certified tester. We handle commercial assembly testing and repair across Arvada and submit to the water utility directly.
Pressure transients in the distribution system
The municipal distribution system experiences pressure transients — brief drops or reversals — during fire suppression activity, main breaks, and operational changes. These transients are normal and managed, but they are exactly the scenario that backflow preventers are designed to handle. An untested or failing assembly provides no protection during those events.
Compliance and property sale implications
An unresolved backflow compliance notice from Arvada Water can result in service interruption. At property sale, a missing or non-compliant assembly is a defect that must be disclosed or corrected before closing. Staying current on testing avoids both problems. For commercial properties, see also commercial plumbing services for a full maintenance picture.
How we conduct backflow testing
- 1
Schedule at the right time
For irrigation systems, testing typically occurs at spring startup when the system is active and pressurized. Commercial assemblies can be tested year-round. We confirm your compliance window and schedule accordingly.
- 2
Differential pressure test
We connect a calibrated differential pressure test kit to the assembly's test cocks and measure the performance of each check valve and the relief valve under static and flowing conditions. This is the only test method accepted by Colorado water utilities.
- 3
Pass or fail determination
An assembly passes if the check valves hold differential pressure above the minimum and the relief valve opens when required. A failure is specific — we tell you which component failed and what repair is needed.
- 4
Repair if needed
If the assembly fails, we rebuild or replace the failing components immediately when possible, then re-test in the same visit. A repaired assembly gets a clean test report.
- 5
Submit results to the utility
We complete the test report in the format required by Arvada Water and submit on your behalf. You receive a copy for your records.

Backflow testing across Arvada's residential and commercial properties
Arvada Water enforces the annual backflow testing requirement actively — unresponsive property owners can receive a compliance notice that, if unaddressed, leads to service interruption. We see a predictable rush of scheduling calls each spring as irrigation systems activate and homeowners receive reminders. Booking in late winter or early spring avoids the wait.
Commercial properties in Arvada — particularly restaurants and food-service businesses in the Olde Town area and along commercial corridors — typically have multiple assemblies: a reduced-pressure zone assembly on the main connection and separate units on kitchen equipment or grease trap water connections. We test and document all assemblies in a single visit and submit the complete package to the water utility.
If you manage a homeowner's association or a multi-family property and need to coordinate testing across multiple irrigation points or units, call us. We work with property managers on a scheduled basis and can build testing into a broader commercial plumbing maintenance program.
How Much Does Backflow Testing Cost in Arvada, CO?
Backflow testing is a flat-rate, standardized service — the price is quoted upfront and covers the certified differential pressure test, the required report, and submission to Arvada Water on your behalf. As general guidance, residential irrigation backflow testing in the Arvada area is a modest annual service that most homeowners find very affordable given that it is a compliance requirement. Commercial properties with multiple assemblies are priced per assembly tested, with multi-assembly discounts available when we test all units in a single visit. If the assembly fails and needs repair or rebuild, that work is quoted separately before any parts are ordered.
The main cost variables are the number and type of assemblies at your property (a simple residential double-check valve vs. a commercial reduced-pressure zone assembly) and whether a repair or replacement is needed after a failed test. An assembly that has frozen and cracked over a Colorado winter typically needs full replacement — we quote that clearly before proceeding. To schedule your annual test before the spring rush, call (207) 419-2600.
What affects the price
- Number of assemblies at the property requiring testing
- Assembly type — double-check, reduced-pressure zone (RPZ), pressure vacuum breaker
- Whether repair or replacement is needed after a failed test
- Commercial vs. residential scope and reporting requirements
- Scheduling timing — spring demand period vs. off-season
- Whether irrigation startup is combined with the testing visit

Questions & answers
Backflow Testing FAQs
Straight answers about this service in Arvada. Call us 24/7 if your question is not here.
Yes. Colorado state regulations and Arvada Water's cross-connection control program require annual testing of all backflow prevention assemblies on connections with a significant hazard designation — which includes virtually all irrigation systems, commercial connections, and fire suppression connections. Missing the testing window can result in a compliance notice.
Testing must be conducted by a certified backflow assembly tester — someone trained and tested specifically on the differential pressure test procedure and the specific assembly types. Plumbers who are not certified testers can install and repair assemblies but cannot legally conduct and sign off on the annual compliance test.
A failed test means the assembly is not providing the cross-connection protection it is supposed to. We repair or rebuild the failing components in the same visit when possible and re-test to confirm it passes. The final submitted report reflects the passing result after repair.
Yes, replacement is often the right call when a double-check or RPZ assembly is cracked from freezing or simply old. We install the replacement and conduct the first compliance test on the new assembly. Drain your irrigation system in the fall and insulate the assembly box to prevent this — it is a common winter casualty in Arvada.
Yes. We test reduced-pressure zone assemblies, double-check assemblies, and pressure vacuum breakers on commercial connections of all types. We document all assemblies and submit the complete test report package to Arvada Water. Call today for service availability and upfront estimate options.
For an outdoor irrigation assembly in an accessible location, you do not need to be present — we can test and submit the report without you on site, then provide your copy electronically. For indoor assemblies or commercial properties where access requires someone to let us in, we coordinate a time that works. Let us know your situation when you schedule.
Schedule a test as soon as possible if you have an irrigation system or any commercial connection. Arvada Water tracks compliance by address, so the utility may already have your property flagged if the previous owner missed a testing cycle. We can test, submit the report, and get you current in one visit. If the assembly is old or has never been serviced, we will tell you honestly whether it needs rebuild or replacement.
