Booking a test versus letting it slide
An overdue test can mean a notice from the supplier. A failed assembly can mean contaminated water. Six differences.

How a backflow test is booked and done
Four steps from a reminder notice to a recorded result.
Call and describe
Where the assembly is, what it protects and what your supplier asked for.
Plan the shutdown
Water to the protected line is off for a short time during the test. Same-day service is available.
Run the test
A gauge set checks the checks and relief valve, and the readings are written down.
Pass, or repair and retest
A pass is recorded. A failure is repaired and tested again.
What moves the cost of backflow testing
A test on a single sprinkler assembly and a set of assemblies in a large building are different jobs. These factors explain the range.
Number of assemblies
Each device is tested on its own.
Type and size
Larger, more complex assemblies take longer.
Location
A visible box in the yard versus a vault or a tight mechanical room.
Condition
Worn parts mean a repair kit or a replacement beyond the test.
Reporting
Some suppliers ask for results to be submitted on their schedule.
Have this ready for the call
- Type and location of each assembly
- Your supplier’s notice or deadline
- Any past test results you have
- When water can be shut off for a short time

A cross-connection is any link between clean drinking water and something that is not.
How water can go the wrong way
Drinking water normally moves outward from the main under pressure. If pressure at the main drops, for instance after a main break or heavy fire-hydrant use, the flow can reverse and pull water from wherever the pipe leads. That is back-siphonage. The other direction is back-pressure, when a boiler or pump pushes water into the supply at higher pressure. A garden hose left in a stock tank, a sprinkler head sitting in a puddle or a hose clipped to a chemical sprayer can each pull their contents into your home plumbing.
The point of backflow testing in Klamath Falls, OR is to check the gates meant to stop that from happening. Klamath Falls municipal water is groundwater drawn from City wells and treated with chlorine only, which is why the protection that follows it matters.
| Hazard | How it happens | Protection |
|---|---|---|
| Sprinkler heads in soil | Back-siphonage after a pressure drop | Pressure vacuum breaker or double check |
| Garden hose in a tub or pool | Hose end below the water line | Hose bib vacuum breaker |
| Boiler feed | Back-pressure from the boiler | Reduced pressure assembly |
| Fire sprinkler line | Stagnant, treated water | Double check assembly |
| Carbonator or chemical injector | Fluid pulled into supply | Reduced pressure assembly or air gap |
Simple protection you can add today
The simplest protection is a threaded vacuum breaker on every outdoor hose bib. It screws onto the spout and lets air in when pressure falls so water cannot be drawn back. Some modern hose bibs include one built in. Never leave a hose end submerged, and keep the end of a hose away from fertilizer sprayers and tubs unless a breaker is fitted.
- Hose bib vacuum breakerScrews on the spout. Check that it is not stuck open.
- Air gapKeep a gap between the faucet and the water in any basin.
- Hose endsNever in a bucket, tub, pool or tank.
- Irrigation assemblyTested on the supplier’s schedule.
Which properties have assemblies that need testing
Requirements are set by your water supplier, not by this page.
Homes, businesses and special systems
Lawn sprinkler systems are the most common case in homes. Properties with fire sprinkler lines, boilers, pools with fill lines, commercial kitchens, carwashes or shops with chemical equipment may also carry assemblies. Some suppliers require periodic tests on certain device types. Ask your water supplier, which in the city is the Klamath Falls Water Division, what applies to your address and how often.
Business owners often hold several assemblies at once, which is why the commercial plumbing page lists backflow among scheduled tasks.
| Property | Assemblies often found |
|---|---|
| Home with lawn sprinklers | Pressure vacuum breaker or double check |
| Restaurant | Dishwasher, carbonator, boiler |
| Shop with an irrigation system | Irrigation assembly |
| Building with fire sprinklers | Double check or reduced pressure |
| Rental with a boiler | Boiler feed assembly |
Spotting the assembly
An irrigation assembly is usually a brass or bronze unit with two shutoffs, a couple of test cocks and sometimes a bonnet that points up. It sits above ground in a box or beside the house. Reduced pressure assemblies have a relief port on the underside that may drip when something is wrong. If you are not sure whether you have one, trace the irrigation supply back to where it connects to the house line.
Trace the sprinkler line
Follow it from the first valve box toward the house.
Look for two shutoffs
Handles with test cocks between them.
Check for a relief port

Note what it protects

What happens during a backflow test
A test takes a short time per assembly and tells you whether the gates still hold.
A gauge, a sequence and a written result
The tester connects a differential gauge to the test cocks, closes the shutoffs in order and watches how the pressure behaves across each check valve. A good check holds against reversed pressure. A relief valve opens when it should and stays shut when it should. The readings are written down and the assembly gets a pass or a fail. Water to the protected line is off briefly, so sprinkler zones go quiet for a little while.
If the supplier asks for the result to be submitted, tell the plumber so the record can be prepared. The result also helps you if there is ever a dispute about the state of the assembly.
| Step | What is checked |
|---|---|
| First check valve | Holds pressure against reverse flow |
| Second check valve | Holds pressure against reverse flow |
| Relief valve (if fitted) | Opens at the right pressure difference |
| Shutoffs | Close and open freely |
Getting the site ready
Clear brush and snow from around the box. Tell anyone using water that it will go off briefly. Have any notice from the supplier on hand. If the assembly is in a vault or a mechanical room, make sure the plumber can reach the test cocks.
- Clear the areaWeeds, mulch and snow.
- Warn the household or staffWater to the line is off briefly.
- Bring the noticeDeadline and device information.
- Open the roomIf it is inside a building.
Why an assembly fails and what the repair involves
Most failures are small rubber or spring parts, not whole units.
Common causes
Check valves depend on rubber seats and springs. Debris can lodge under a seat so it no longer seals. Seats harden and crack with age. Springs lose tension. A relief valve that weeps may have a fouled disc. Many of these repairs are a rebuild kit that is swapped during the test visit. When the body is cracked or corroded, or the parts are no longer made, replacement is the answer. A failed assembly means that line has lost its protection until it is fixed, so do not leave it.
| Failure | Likely cause | Remedy |
|---|---|---|
| Check valve leaks backward | Debris or worn seat | Clean or replace the seat |
| Relief port discharges | Fouled disc or fluctuating supply | Service the relief valve |
| Cracked body | Freeze or impact | Replace the assembly |
| Shutoff will not close | Corroded stem | Replace the shutoff |
Water that smells or tastes wrong near an assembly
Do not drink from the line. Close the supply to the assembly and call. See how to shut off your main water valve.Protecting an assembly from the cold
An exposed assembly is one of the first things to break in a hard freeze.
Drain, cover, and check in spring
Above-ground assemblies hold water that expands when it freezes. Close the supply shutoff, open the test cocks to drain, leave them open and wrap the assembly in an insulated cover made for the purpose. Do not wrap it in plastic, which traps moisture. Buried vault units are less exposed but still benefit from checks. In spring, test cocks should be closed again slowly, and a test after a hard winter is a sensible way to catch damage. See how to prevent frozen pipes for related steps.
Shut off the supply
Before the first freeze.
Open the test cocks
Leave them open to drain.
Cover the assembly
Insulated cover, not plastic.
Retest in spring
Catch cracks before the season.
If it already cracked
Close the supply and call. A cracked body is replaced, not patched. Watch for water entering the ground or the building. Burst pipe repair explains what to expect for the line that feeds it.
| Sign | Action |
|---|---|
| Water gushing at the unit | Close the supply and call |
| Slow drip after a freeze | Call; do not wait for spring |
| Cracked plastic bonnet | Replace the part or the assembly |
