How a backflow call goes
Four steps from the notice to a passed test.
Call
Say you need a backflow test or have a device problem.
Describe the device
Where it is, what it protects, and anything written on the notice.
Test or service
Same-day service is available. The assembly is tested with gauges.
Repair and retest
If it fails, worn parts are replaced and the device is checked again.
What decides backflow pricing
A simple test on an accessible device is a different job from a repair or replacement. These are the factors.
Type and size of the device
A small residential assembly is simpler than a large commercial one.
Number of devices
Properties with several assemblies take longer to test.
Access
A device in a clear box is quick. One buried, overgrown or in a tight space takes more work.
Repair needed
Replacing worn rubber parts is a smaller job than replacing the assembly.
Paperwork
Some suppliers want a report filed. Ask what your notice requires.
Have this ready for the call
- Any notice or letter you received
- Where the device sits and what it serves
- Any marking or tag on the assembly
- Whether it is leaking or just due for a test

Water is supposed to move one way
Clean water enters a building at a pressure higher than the pipes inside. Backflow is when that flow reverses, and used or contaminated water gets pulled or pushed back toward the supply. It happens two ways. Backsiphonage occurs when supply pressure drops, for example when a main breaks or a hydrant is opened, and the pipes pull water backward. Backpressure occurs when pressure on the building side exceeds supply pressure, as with a boiler or a pump.
A backflow preventer is a valve assembly that keeps water moving one way. It matters for the whole neighborhood, not only the building, because a reversal can carry fertilizer, pool chemicals or dirty water into the shared supply.
| Cause | What happens | Example |
|---|---|---|
| Backsiphonage | Supply pressure drops and water is pulled backward | A main break or heavy fire flow |
| Backpressure | Building pressure exceeds supply pressure | A boiler or booster pump |
| Cross-connection | A pipe links drinking water to something not safe to drink | A hose left in a bucket of chemicals |
| The safeguard | A device that blocks reverse flow | Backflow preventer |
Why a test is needed at all
A backflow assembly contains check valves with springs and rubber seals. Those wear, collect grit or get stuck. Nothing about a worn device is visible from the outside, because water still flows through it normally. Only a test shows whether the valves still seal. That is why backflow testing in Lake Elsinore, like anywhere, is its own routine.
This page does not say who requires a test at your property, how often, or who may perform it. Those requirements come from your water supplier and the city. Ask EVMWD or the city building department what applies to your address, and bring any notice you received when you call.
- Check valvesSpring-loaded valves that must close tightly.
- Relief valveOn some assemblies, opens to dump water if both checks fail.
- Shutoff valvesAllow the assembly to be isolated for the test.
- Test cocksSmall ports where the gauge connects.
- Rubber sealsThe parts that wear first.
Common places to find one
Devices show up wherever drinking water could meet something it should not. The size and type change with the hazard, from a small hose attachment to a large assembly on a business line.
| Where | Why a device is there | Usual appearance |
|---|---|---|
| Outdoor hose bib | A hose could siphon chemicals back | Small brass vacuum breaker on the spigot |
| Lawn sprinklers | Irrigation water can hold fertilizer or soil | Raised valve assembly near the house or a box in the ground |
| Boiler or heating loop | Treated water can push back | Compact assembly on the fill line |
| Pool or spa fill line | Pool water must not reach the supply | Device on the fill or an air gap |
| Fire sprinkler line | Stagnant water in fire lines | Large assembly where the line enters |
| Commercial kitchen or shop | Equipment tied to the supply | Assembly near the meter or on equipment |
Business properties often have more than one device. See commercial plumbing for work on those. The faucet-level vacuum breakers on hose bibs sometimes crack or drip; faucet repair handles those.
The main kinds of backflow assembly
From simple to heavy duty
The device type depends on the level of hazard. A hose-bib vacuum breaker is the simplest. A pressure vacuum breaker sits above the highest outlet it protects, usually on irrigation. A double check valve assembly has two check valves in series, for lower-hazard connections. A reduced pressure assembly adds a relief valve between two checks and is used where the hazard is higher.
You do not need to choose. The water supplier decides which type a connection needs. If a device has to be replaced, the new one should match the type required for that connection, so describe your existing one and read the label.
| Type | How it works | Typical use |
|---|---|---|
| Hose-bib vacuum breaker | Air inlet breaks the siphon | Outdoor taps |
| Pressure vacuum breaker | Check plus air inlet, raised above outlets | Irrigation |
| Double check assembly | Two checks in series | Lower-hazard lines |
| Reduced pressure assembly | Two checks plus a relief valve | Higher-hazard lines |
| Air gap | Open space between outlet and spill level | Where a gap is workable |
How to tell whether you have a device
Look near the water entry and the irrigation
Walk to where the water line enters the house and look near the meter box. A brass assembly with two shutoff handles and small test ports on the side is a backflow assembly. A device on a sprinkler system often looks like a brass or plastic valve standing above the ground with a cap on top. Hose bibs may have a small brass cap-shaped piece threaded on.
A tag or tape with a serial number is normal. Keep any paperwork from past tests. If you cannot find a device and think you should have one, mention it when you call. Some properties are on a program list from the water supplier and others are not, and the call is the fastest way to find out whether yours is.
- Near the meterBrass assembly with two handles and side ports.
- Sprinkler systemA raised valve above ground, or a box in the lawn.
- Hose bibsA small cap-shaped vacuum breaker on the spigot.
- Past paperworkOld test reports with serial numbers.
- Your noticeThe letter often names the device and its location.
How backflow testing in Lake Elsinore works, step by step
Notify and prepare
Water to the assembly will be shut off briefly, so plan for no water to that line.
Attach the test kit
A gauge kit connects to the test ports on the assembly.
Check each valve
The tester measures whether each check valve holds pressure, and whether the relief valve opens on assemblies that have one.
Record the result
The reading and the device details go on a report.
Repair if needed
Worn rubber parts and springs can usually be replaced. A badly worn assembly is replaced.
Retest and restore
After a repair the assembly is tested again and water is turned back on.
Who files the report, and by what date, depends on your water supplier. Ask EVMWD or the city. If the assembly sits on a supply line with other problems, see water line repair.
Leaks, failed tests and what they mean
A device that drips or sprays
Many assemblies have a relief port that drips if the checks are not sealing, and a vacuum breaker that spits when its seal is worn or debris is caught. A little water after a pressure surge can be normal on some designs, but a steady drip is not. Do not plug the port. It is there so a failure shows itself instead of hiding.
Shut off the water to the assembly at its inlet valve and call. If it is on an irrigation line, turn off the irrigation supply too. If water is spreading, see how to shut off your main water valve.
| What you see | Likely cause | Direction |
|---|---|---|
| Steady drip from relief port | Check valve not seating | Repair |
| Spray from vacuum breaker cap | Worn seal or debris | Repair |
| Failed test | Worn checks or a stuck relief | Repair, retest |
| Cracked body | Damage or age | Replace |
| Device missing or removed | Cut out or stolen | Replace |
Plugging a drain port does not fix it
People sometimes cap a dripping relief port to stop the water. That removes the warning and may defeat the safeguard. A drip needs a repair. Missing devices are another issue, because a removed or bypassed assembly leaves the connection unprotected.
- Do not cap relief portsThey are part of the design.
- Do not remove partsLeave seals and springs alone.
- Do not bypassA pipe around the device defeats it.
- Keep the box clearRoots, debris and standing water cause problems.
- Keep paperworkTest reports prove compliance.
If you suspect contaminated water
Stop using the water
If it smells, tastes or looks wrong after a pressure event, do not drink or cook with it.
Shut off the line
Close the main or the supply to the suspect fixture.
Do not mix chemicals
Hoses left in buckets, fertilizer or pool chemicals should be pulled out.
Call
The line is open 24/7. Same-day service is available.
Tell the water district
If the whole street is affected, report it to EVMWD.
Unsure about the water?
Treat it as not safe until it is checked. Use bottled water for drinking and cooking. If you are worried about your health after drinking it, contact a doctor or poison control.
