Certified Backflow Testing for Residential, HOA & Commercial Properties

Your irrigation system contacts pesticides, fertilizers, and animal waste when it runs. The backflow device on your system helps keep those contaminants from reversing into your property’s water supply. Our certified technicians at Conserva Irrigation of Bend inspect all components of that device and deliver the annual backflow testing Bend property owners are required to complete under City of Bend Cross Connection Control Code and Oregon Administrative Rule 333-061-0070.

We serve residential customers, homeowners associations, and commercial property owners throughout the Bend area, including Redmond and the broader Deschutes County region.

Don’t wait until the season is underway and testers are booked solid. Call Conserva Irrigation of Bend at (458) 310-5535 to schedule your backflow testing in Bend before the irrigation season gets ahead of you.

What Bend Requires from Property Owners

City of Bend Ordinance 14.30 and Oregon Administrative Rule require that approved backflow assemblies on irrigation systems be tested at installation, annually, after any repairs, and after relocation. Each year, the City sends letters reminding water customers that the annual test is due. The responsibility for scheduling a certified tester, completing the test, and ensuring results reach the City of Bend Water Services Department falls on the property owner.

Testing must be performed by an Oregon Health Authority (OHA)-certified backflow assembly tester. Our technicians carry that certification. The assembly being tested is located on private property between your water meter and your irrigation system, not the assembly inside the City’s meter box, which the City owns and tests separately.

Central Oregon winters can crack and damage backflow assemblies. The City of Bend recommends scheduling early in the irrigation season, and for good reason: certified testers fill up quickly once spring arrives.

What Our Backflow Testing Service Covers

Our certified technicians inspect all components of the backflow device system, covering both the pressure vacuum breaker (PVB) and the reduced pressure zone valve (RPZ). Testing is typically performed before turning the irrigation system on for spring. Because our technicians are full-service irrigation professionals, we can pair the test with a spring startup, a full system inspection, or any repairs needed, all in a single visit.

If the assembly fails its test, we’re positioned to identify the issue and discuss the repair before your irrigation season is delayed.

One Provider for Testing, Repairs & Water Efficiency

Most backflow testing options in Bend come from backflow-only providers or general contractors with no irrigation background. Conserva Irrigation of Bend takes a different approach. The same certified technicians who test your backflow device also inspect, repair, and optimize your entire irrigation system for water efficiency. A failing assembly doesn’t send you hunting for a second provider.

We use Toro and Hunter products, apply smart irrigation technology that can reduce water usage by up to 60%, and back every service with a satisfaction guarantee. Whether you need annual backflow prevention in Bend or a full system overhaul, you’re working with one team that understands your system from the meter to the last rotor head.

Schedule Your Backflow Test Before the Season Fills Up

If you’ve received a letter from the City of Bend, are opening your irrigation system for the season, or can’t remember when your backflow device was last tested, now is the right time to act. Early scheduling can help you secure a preferred appointment time and avoid a compliance gap heading into summer.

Conserva Irrigation of Bend serves Bend, Redmond, and surrounding areas throughout Deschutes County. Call us at (458) 310-5535 to schedule your backflow testing today.

Understanding Backflow and Why It Matters

Backflow occurs when a change in water pressure causes water to reverse direction, pulling from a contaminated source back into the drinking water supply. Irrigation systems are one of the most common cross-connection risks for residential properties because they operate in direct contact with pesticides, fertilizers, and animal waste applied to landscaped areas.

A pressure drop can be triggered by a water main break, firefighting activity drawing high volumes from the system, or routine main flushing. When pressure drops suddenly, contaminated water from irrigation pipes can be pulled back toward the drinking water supply. Discolored water at a tap or an unexplained drop in household water pressure can both be signs that a backflow event has occurred.

Pressure Vacuum Breakers vs. Reduced Pressure Zone Valves

Two backflow device types are commonly found on irrigation systems in the Bend area. Knowing which one you have helps clarify what standard applies to it.

A pressure vacuum breaker (PVB) is one of the most common devices on residential irrigation systems. It protects against back-siphonage by venting to atmosphere when upstream pressure drops. A reduced pressure zone valve (RPZ) provides a higher level of protection using a differential pressure relief valve between two check valves and is typically required where a greater contamination risk is present, such as on commercial properties or systems with chemical injection.

Both device types are located on private property between the water meter and the irrigation system, not inside the City of Bend water meter box, which the City owns and maintains separately.

When a Backflow Assembly Fails Its Test

A failed annual test doesn’t always mean the assembly needs to be replaced. Backflow assemblies are mechanical devices, and their internal components can wear, corrode, or sustain freeze damage over Central Oregon winters. In many cases, repairs to seals, springs, or check valves can restore proper function and bring the assembly back into compliance.

When an assembly fails, it must be repaired and retested before the irrigation system can be used for the season. Our certified technicians are equipped to identify issues during the testing process and, because we provide full-service irrigation care, can handle a repair and arrange retesting within the same service relationship rather than sending you to a separate provider.
