Water in a pipe normally flows one way, from the supply into your home. Backflow is that flow running backward.
How can used water get into the drinking supply?
Two things cause it. Back-siphonage happens when supply pressure drops, perhaps after a main break or heavy firefighting draw, and the lowered pressure pulls water backward. Back-pressure happens when a connected system, such as a boiler or a pumped irrigation zone, has more pressure than the supply and pushes water in the wrong direction.
What gets drawn back depends on what is on the other end. A sprinkler line might hold fertilizer residue or soil. A hose in a pool might hold chlorine. A boiler loop can hold treatment chemicals. A backflow device, built with spring-loaded check valves, closes the path. Because springs and rubber wear, the device is tested on a regular schedule.
| Device | Where it is usually found | What it relies on |
|---|---|---|
| Hose bib vacuum breaker | Outdoor spigots | A small atmospheric port |
| Atmospheric vacuum breaker | Downstream of irrigation valves | An air inlet and a float |
| Pressure vacuum breaker | Above-ground at irrigation systems | A check and an air inlet |
| Double check valve assembly | Fire lines and low-hazard commercial lines | Two check valves |
| Reduced pressure assembly | High-hazard sites such as chemical feeds | Two checks and a relief valve |
Does a home need this, or only a business?
A home with a sprinkler system, a pool fill line, a fire line or a well-and-city connection usually has a device. A home without any of those may have only the small hose bib breakers. Businesses with boilers, fountains, car wash gear or medical equipment are more likely to need a larger one.
Your water provider writes the rules, so call or check your bill to find out which one serves your address. Supply in the Green Valley area is split among several providers, and each handles testing notices in its own way.
- Sprinkler or drip systemAlmost always has a device.
- Pool or spa fillOften needs a vacuum breaker.
- Fire sprinkler lineA double check is typical.
- Boiler or chemical feedUsually a reduced pressure assembly.
- Only outdoor hose bibsSmall breakers on each spigot.
Irrigation backflow assemblies in the desert
Desert yards run on drip lines, spray heads and timers. The device at the head of that system is the one most homes need tested.
What wears out a sprinkler backflow device here?
A pressure vacuum breaker stands above ground on a short riser. In Green Valley, summer sun bakes the plastic and cooks rubber seals, and a cold snap can freeze water inside the body and crack it. Monsoon downpours can flood the valve box and sit around the device for hours. Sand and silt also work their way into seats and keep them from sealing.
Look at your assembly once a month during watering season. Weeping at the top, a spray from the vent or constant dripping at the base are all signs that a seal has lost its grip. If a pipe feeding the zone has broken, see water line repair. For bigger yard line trouble, leak detection helps find where the water goes.
Look for spitting
Water at the vent means the unit is relieving.
Check the box
Silt or standing water in the valve box should be cleared.
Check the riser
A tilted, cracked or sun-faded body needs replacement.
Schedule the test
Yearly, or when your provider’s notice arrives.
How do I protect the device from heat and cold?
An insulating cover made for backflow devices helps in a freeze, and a ventilated shade structure helps against sun. Draining the assembly before a freeze, by opening the test cocks and shutting the upstream valve, protects it. Do not wrap it in foil or plastic, which can trap heat or moisture.
If you are replacing yard lines, call 811 before any digging. The tester or plumber can also raise or relocate a device that sits in a low spot.
| Hazard | Effect on the device | Prevention |
|---|---|---|
| Summer sun | Brittle plastic, hardened seals | Cover or shade |
| Rare winter freeze | Cracked body | Insulated cover, drain down |
| Monsoon flooding | Silt in seats, submerged vent | Raise or relocate |
| Mower or trimmer hits | Chipped riser | Guard or marker post |
| Hard mineral buildup | Sticky checks | Rebuild at test time |
On test day: how a backflow assembly is checked
A test takes a gauge kit, a few valves and a bit of time. The result is a pass or a fail for each part.
What does the tester actually do?
The tester closes the shutoff valves on either side of the device, then attaches a test kit to small ports called test cocks. Each check valve is held to a pressure standard and the relief valve, if present, is checked for the pressure at which it opens. Air inlet valves on vacuum breakers are checked for opening at the right point. Every reading is written down.
While the water is off, plan on a short interruption to the line behind the device. For an irrigation zone it affects only the yard. For a business, ask when is a good moment to shut off a connected line. A device that passes gets a report. One that fails is repaired and retested.
Shut the valves
Both sides of the device are closed.
Attach the kit
The gauge connects to the test cocks.
Read each part
Check valves, relief valve and air inlet are measured.
Record the result
A pass or a fail goes on the report.
Water flooding from a device
Close the valve that feeds it, then call. A spray from a failed assembly can erode soil, flood a valve box and waste a lot of water quickly. Keep children and pets back from the spray.
What is a typical pass or fail reading?
A check valve passes when it holds the minimum pressure drop across its seat. If the pressure falls quickly, the seat is leaking and the valve fails. The relief valve passes when it opens above a minimum differential. A vacuum breaker passes when the air inlet opens before pressure falls to a set low point.
Most failures come from debris on a seat, a worn rubber disc or a weak spring. Those are inexpensive parts, so a failed test is often a short repair, not a new device.
| Component | Pass means | Common failure cause |
|---|---|---|
| First check valve | Holds back pressure | Debris on the seat |
| Second check valve | Holds back pressure | Worn disc |
| Relief valve | Opens at the right differential | Stuck or dirty |
| Air inlet valve | Opens before pressure is lost | Stuck float |
| Shutoffs | Seal tightly | Mineral buildup |
Who needs backflow testing in Green Valley and when
The rules come from your water provider. A letter or a bill insert is usually the first sign.
| Property | Typical device | Testing pattern |
|---|---|---|
| Home with sprinklers | Pressure vacuum breaker | Yearly or per provider notice |
| Home with a pool fill line | Vacuum breaker | Per provider notice |
| Home with a fire line | Double check assembly | Yearly |
| Small restaurant | Double check or reduced pressure | Yearly |
| Office with a boiler loop | Reduced pressure assembly | Yearly |
| Strip center with irrigation | Pressure vacuum breaker or double check | Yearly |
| Mobile home park meter | Double check at the meter | Per provider notice |
Your water provider may be the Green Valley Domestic Water Improvement District, the Community Water Company of Green Valley or another supplier, depending on your address. Call the one on your bill to ask how testing is tracked. For shops and offices, the commercial plumbing page covers other building work.
What if I get a notice and do not know what it means?
Read it for four things: the address of the device, the type, the due date and who should receive the result. Many notices name an approved list of testers or allow your own plumber to file. If anything is unclear, phone your provider, then call to schedule the test.
Missing a deadline can lead to follow-up notices, so do not wait until the last week. Ask the provider or the county building department if you need to know what applies to your particular property.

- Who receives the reportProvider or an online portal.
- Contact for questionsA phone number on the letter.
What happens when a backflow device fails the test
A failed test is common and fixable. The device stays out of compliance until it is repaired and passes again.
Is a rebuild or a replacement the better choice?
A rebuild replaces the springs, discs, seals and sometimes the cover. It suits a body that is intact and a model that still has parts. Replacement makes sense when the body is cracked, corroded or discontinued, or when repeated rebuilds cost more than a new unit. A new device also gives a chance to correct poor placement, such as an assembly sitting in a low spot that floods.
Retest after the work and file the new result. If the assembly sits on a line with old pipes, ask for a look at the rest of the run, and see pipe repair if something upstream is leaking.
| Situation | Better option |
|---|---|
| Fouled seat, intact body | Rebuild |
| Cracked body from a freeze | Replace |
| Parts no longer made | Replace |
| Repeated failures in a short time | Replace and relocate |
| Device in a flood-prone spot | Raise or relocate |
What else should I check at the same visit?
While the plumber is there, test the shutoff valves on both sides, look at the pipe leading to the device and note the pressure. A line with high pressure stresses check valves. Ask whether a pressure regulator makes sense.
For a worn irrigation line that keeps breaking, see how to find a water leak in your house for ways to trace a loss. If you are weighing a new service line, the plumbing services page lists every job on the line.

Keeping your backflow records straight
A pass today means little if the paperwork never reaches the right office.
Who gets the report, and how long should I keep it?
Most providers want the result filed with them directly. Some use a portal and some accept a paper form. The tester can usually submit it, but confirm that before the visit. Keep a copy of every test report with the property records, along with the serial number and installation date.
When a property sells, the new owner needs to know the device exists and when it was last tested. When tenants change, tell them where the assembly is and who to call. If you manage a business, add the device to your maintenance calendar. Read more in the how to choose a plumber guide.

How do I make the next test easy?
Keep the device clear. Trim plants that grow around it, keep the valve box free of silt and mark its location so mowers and trimmers stay away. Know where the shutoffs are, and make sure the gate is not locked on test day.
Tucson-area and Sahuarita-area owners can book through the same line. See the Tucson and Sahuarita area pages for coverage.
| Prep | Why it helps |
|---|---|
| Clear growth around the device | The tester needs room for the kit |
| Open gates | Access is faster |
| Know your shutoffs | The water can be isolated quickly |
| Have the last report ready | Shows previous readings |
| Note any dripping | Helps the tester start in the right spot |
