Did you know that contaminated water from backflow can lead to serious health risks? Heart disease and certain types of cancer are just some examples that ever spread through contaminated water.
Backflow testing is a significant safety measure that protects your home’s clean water supply from contamination. Backflow happens at any point where clean and dirty water lines connect. Changes in water pressure or burst water mains often trigger this issue. Your drinking water could become tainted with dangerous materials – human waste, pesticides, or chemicals.
Regular backflow testing prevents hefty fines up to $2,000 and potential disconnection of your water service. This piece will help you understand everything about backflow testing and prevention, whether you’re a new homeowner or someone who wants to protect their family’s health.
What is Backflow and Why Should Homeowners Care?
Backflow threatens your home’s water system by allowing contaminated water to flow backward into your clean water supply. This happens at cross-connections where potable water lines meet non-potable sources.
Understanding the backflow process
Your water system can experience backflow in two ways. Backsiphonage occurs at the time of sudden pressure drops in the distribution system from main breaks, pump failures, or firefighting water usage. Backpressure happens when non-potable source pressure exceeds your drinking water system’s pressure due to pumps, heating systems, or elevation differences.
Clean water in your home can get contaminated with substances from your plumbing system or outside environment during backflow events. Water distribution systems experience 25-30 breaks per 100 miles of piping each year, which creates many opportunities for backflow incidents.
Health risks of contaminated water
Backflow contamination poses serious health risks. Your drinking, bathing, and cooking water can become tainted with microbes, bacteria, and chemicals. Even tiny amounts of contaminants lead to stomach problems like diarrhea, vomiting, and nausea. These health issues affect young children, pets, and elderly people more severely.
Cross-connections and backflow caused many waterborne disease outbreaks throughout history. From 1920 to 1980, they were responsible for 78% of outbreaks and 95% of illness cases linked to community distribution system contamination in the United States. Backflow incidents often involve these chemical contaminants:
- Copper, chromium, and ethylene glycol
- Pesticides and insecticides
- Chlorine from pools and spas
- Soaps from household fixtures
Common causes of backflow in residential properties
Your home faces several backflow triggers. Water pressure changes from main breaks or fire hydrant use rank as the biggest problem. Irrigation systems create risks by pulling fertilizers, pesticides, and animal waste into your water supply.
Garden hoses create another common hazard. They can siphon contaminants back into your drinking water during pressure drops if left in pools, chemical buckets, or puddles.
Bad plumbing installation prevents proper water flow direction. Construction or remodeling work on your property might create temporary cross-connections that cause backflow.

Warning Signs That Your Home Needs Backflow Testing
You can save money on repairs and avoid health risks by spotting backflow problems early. Your home’s water system shows certain signs that tell you it’s time to test the backflow. Let’s get into the most obvious signs that your backflow prevention device needs expert help.
Changes in water pressure or flow
Your home’s sudden water pressure changes often point to backflow issues. A failing backflow prevention device might cause your water supply pressure to drop by a lot. The backflow creates a vacuum effect in your pipes that slows down proper water flow.
Fluctuating water pressure should raise concerns, especially when you have contaminants entering and blocking the system. These pressure changes might happen randomly and disrupt your daily household tasks.
You might hear strange noises from your plumbing system. A leak or faulty part in your backflow preventer often makes hissing or whistling sounds. The problem likely lies in your water supply system if these sounds continue after running water for several minutes.
Unusual water color, taste, or odor
The need to test backflow becomes obvious when you notice discoloration. Contaminated water looks brown, yellow, pink, or cloudy. Your clean water supply gets tainted with sediment, rust, or other contaminants due to backflow. Any water that isn’t clear could be unsafe.
Odd tastes or smells are another red flag. Your water might suddenly taste bitter, metallic, or like rotten eggs, which shows contamination. These unpleasant changes happen because backflow lets foreign substances into your drinking water. So if your water smells like chemicals or sewage, your backflow prevention system might not be keeping contaminants out.
Note that drinking water that’s discolored, smelly, or tastes strange can harm your health. These warning signs mean you need to take action right away. Contact Western Rooter today to get a free estimate!
How is a Backflow Test Performed by Professionals
Professional backflow testing needs special training and equipment to keep your water system free from contamination. A good understanding of the testing process will help homeowners prepare better for this crucial safety procedure.
Step-by-step testing procedure
Professional technicians follow a systematic approach during backflow testing:
- Original assessment: The technician asks for your permission to temporarily shut off the water supply. This step ensures accurate testing since backflow tests need no-flow conditions.
- Visual inspection: The professional looks for obvious signs of wear, damage, or leaks on the backflow preventer before starting the test.
- Test preparation: Your technician identifies the backflow preventer type and flow direction. They number and bleed the test cocks to clear any debris.
- Valve testing: The technician closes the downstream shut-off valve first. The first check valve might need service if water continues to pour from the relief valve after a few minutes in reduced pressure devices.
- Pressure measurement: The technician uses specialized equipment to measure pressure at different system points. This verifies that check valves stop backflow and relief valves work properly.
Equipment used during testing
Technicians use specific tools to perform accurate backflow tests:
A backflow test kit is the main piece of equipment. It includes a differential pressure gage, needle valves, hoses, test cock fittings, and a carrying case. The differential gage reads pressure differences between two areas and shows a single reading that confirms proper operation.
Test kits come in two types: analog (mechanical) gages or digital (electronic) gages. Digital versions offer computerized calibration features and can show multiple pressure readings at once.
Typical duration and cost for homeowners
Backflow testing is quick and affordable. The whole ordeal takes about 20-30 minutes if no repairs are needed. This small time investment gives important protection to your home’s water supply.
Testing costs usually range from $70 to $90, but prices can go up to $350 based on your location. Several factors affect the price, including test port accessibility, tester certification, and local rules.
Most cities require yearly testing. Some handle the testing themselves for a fee, while others ask homeowners to hire certified private companies. You might face additional repair costs if your backflow preventer fails inspection.

Simple DIY Checks Before Calling the Professionals
Simple checks can help you spot potential problems with your home’s water system before you invest in professional backflow testing. These DIY inspections protect your home from contamination.
Inspecting outdoor faucets and hose connections
Outdoor faucets are among the most common unprotected cross-connections in residential properties. You should get into your hose bibs (outdoor faucets):
- Look for a small cap on the outlet pipe near the valve—this indicates an integrated vacuum breaker that provides built-in protection
- You can install a hose bib vacuum breaker that screws onto the existing threads if your faucets lack this feature
Your garden hoses should never be submerged in pools, chemical buckets, or puddles since this creates a direct path for contaminants to enter your water supply. You should check if your anti-siphon adapters leak—these devices stop water from flowing backward if city water pressure drops suddenly.
Checking irrigation systems
Your irrigation systems can create specific backflow risks because they might contain fertilizers, pesticides, and other chemicals. You should verify the type of backflow prevention installed on your sprinkler system:
The irrigation backflow prevention needs a check to determine if you have an atmospheric vacuum breaker, pressure vacuum breaker, or reduced pressure zone device. Your pressure vacuum breaker must be installed at least 12 inches above the highest sprinkler head. Regular checks for leaks around the backflow device are important—a properly working reduced pressure zone unit might leak water occasionally.
When to schedule professional testing
Professional backflow testing remains crucial despite these DIY checks. You need annual testing with certified testers, usually during spring as irrigation systems become active.
You should prepare for professional testing by:
- Making your backflow prevention device easily accessible
- Shutting off water to appliances and fixtures during testing
- Setting appointments during off-peak hours to minimize disruption
The law requires annual testing in most municipalities—you risk fines or water service disconnection by not complying. Note that proper backflow prevention safeguards your family and your community’s water supply.
