What Does a Standard Backflow Test Cost for Your Property or Device?

If you’re trying to budget for an annual test (or a city notice just landed in your mailbox), the most helpful answer is: a standard backflow test typically costs more or less depending on the device type, access, and how many assemblies you’re testing at once.

What Backflow Testing Long Beach experts recommend is getting a clear quote based on your property type and the specific assembly installed—because a small residential unit and a large commercial RP assembly don’t price out the same.

Atlas Backflow Services put this guide together to help you understand common price ranges, what drives cost, and how to avoid surprise add-ons.

Quick Cost Snapshot (Most Common Price Ranges)

While exact pricing varies by provider, scheduling, and site conditions, these are realistic planning ranges for Long Beach-area properties:

• Typical single-device test (most homes / small sites): $75–$160

• Common commercial / multi-device sites (per assembly, often discounted): $65–$140 each

• Large or high-risk assemblies (e.g., many RP devices, complex access): $120–$250+ per assembly

• After-hours / urgent scheduling: can add $50–$150+

• Retest (if needed after a repair): often $40–$120, depending on provider and timing

What Backflow Testing Long Beach experts recommend is asking whether the quote includes test reporting/submittal (when applicable) and whether there are extra charges for hard-to-access devices.

What “Standard Backflow Test” Usually Includes (And What It Doesn’t)

A “standard” backflow test typically refers to a certified tester verifying that the assembly’s check valves and relief valve (for RP devices) function within required tolerances.A standard test commonly includes:

• Arrival on-site and locating the assembly

• Shutting down water briefly (when required)

• Performing the test with calibrated gauges

• Recording results and preparing required documentation

Often not included (but sometimes bundled) are:

• Repairs (parts + labor)

• Replacement of failed assemblies

• Retesting after repair

• Excavation, access work, or enclosure modifications

• Permit fees (if replacement requires permitting)

As Backflow Testing Long Beach experts recommend, confirm upfront whether paperwork submission is included—especially if your water purveyor requires electronic submittal.

Cost by Device Type (Assembly Type Matters Most)

The type of backflow preventer on your property is one of the biggest cost drivers. Here’s how pricing tends to break down.

1) DCVA (Double Check Valve Assembly)

Common on many commercial services and some lower-hazard applications.

• Typical test cost: $75–$160

  
  

  DCVAs are usually straightforward to test when accessible.

  
  

2) RP / RPZ (Reduced Pressure Principle Assembly)

Used where the hazard is higher (many commercial/industrial uses). It has a relief valve and tighter performance expectations.

• Typical test cost: $95–$220+

  
  

  What Backflow Testing Long Beach experts recommend is budgeting a bit more for RP devices due to added complexity and the higher likelihood of needing maintenance over time.

3) PVB (Pressure Vacuum Breaker)

Common on irrigation/sprinkler systems. Usually outdoors and seasonal.

• Typical test cost: $75–$170

  
  

  Pricing can increase if the assembly is inside a tight cage, above a roofline, or hard to reach.

4) SVB (Spill-Resistant Vacuum Breaker)

Also used for irrigation, designed to reduce water spillage.

• Typical test cost: $85–$190

  
  

  Access and enclosure clearance often decide where it lands in the range.

Cost by Property Type: What You’ll Likely Pay

Because properties tend to have predictable device setups, you can estimate cost by your use case.Single-Family Home (domestic line or small irrigation device)

• Typical: $75–$160 for one assembly

  
  

  Homes often have one testable assembly (sometimes irrigation only). If your assembly is behind landscaping, a locked gate, or in a cramped box, cost can rise.

Multi-Family (duplexes, apartments, condos, HOA master meters)

• Typical: $65–$140 per assembly (often discounted for multiples)

  
  

  Multi-family sites may have a domestic assembly plus irrigation assemblies. What Backflow Testing Long Beach experts recommend is asking for per-device pricing tiers if you have more than one.

Restaurants / Retail / Small Commercial

• Typical: $85–$200 per assembly

  
  

  These sites often use RP assemblies (higher hazard) and may have multiple points (domestic, irrigation, fire line depending on configuration). Scheduling during business hours can also affect access and time on site.

Medical / Lab / Industrial / Manufacturing

• Typical: $120–$250+ per assembly

  
  

  High-hazard sites often require RP assemblies and may have strict access protocols, escorts, or shut-down coordination—factors that influence pricing.

Irrigation-Heavy Properties (large landscapes, campuses, parks)

• Typical: $75–$190 per assembly, with better pricing when testing several at once

  
  

  What Backflow Testing Long Beach experts recommend is batching tests during the same visit to reduce trip and setup costs.

The Biggest Factors That Change Your Price (Checklist)

If you want the most accurate estimate, these are the details that matter most:

• Number of assemblies (multi-device sites often qualify for volume pricing)

• Assembly type (RP tests often cost more than DCVA or PVB)

• Accessibility (locked enclosures, tight vaults, roof access, blocked shutoffs)

• Water shutoff coordination (tenant notifications, business downtime, escorts)

• Time of service (after-hours, weekends, or urgent appointments)

• Reporting requirements (some agencies require specific formats and timelines)

As Backflow Testing Long Beach experts recommend, take a quick photo of the device tag and installation location and share it when requesting a quote—this alone can prevent mispricing.

What If the Device Fails? Understanding Retests and Repairs

A failed test does not automatically mean you need a full replacement. Many failures are repairable (e.g., check module cleaning/rebuild, seals, springs). Common cost add-ons include:

• Repair labor + parts: varies widely by assembly type and condition

• Retest fee: often $40–$120

• Replacement (when needed): can range from a few hundred to several thousand dollars depending on size, permits, and installation complexity

What Backflow Testing Long Beach experts recommend is choosing a tester who can clearly separate test cost from repair cost, and who explains whether repair is reasonable versus replacement.

How to Get the Best Value (Without Cutting Corners)

Price matters, but a correct test and proper paperwork matter more—especially when compliance deadlines are involved. Here’s the practical approach Backflow Testing Long Beach experts recommend:

• Confirm certification and calibration of testing equipment

• Ask what’s included (test + forms + submittal, if required)

• Bundle multiple assemblies into one appointment when possible

• Ensure clear access (unlock gates, clear shrubs, remove stored items)

• Schedule before the deadline to avoid rush fees and limited availability
