Contact Our Expert Plumbers for Professional Backflow Testing Services

Backflow is when water flows in the wrong direction within your plumbing system. Instead of clean water moving from the supply line into your home, contaminated water reverses course, potentially introducing pollutants, chemicals, or waste into your clean water supply.

This reversal can happen due to sudden drops in water pressure or system malfunctions, and it often goes unnoticed until it’s too late. Understanding how backflow works and how to prevent it is essential to protecting your home’s water supply. 

If you believe you have a backflow issue in your house, contact our team to receive support. Our skilled plumbers offer reputable backflow testing services for homeowners in areas of Arizona such as Phoenix, Mesa, Glendale, Scottsdale, Chandler, Peoria, and Tempe. Our staff members have the tools and skills necessary to protect your clean water supply.

How Does Backflow Testing Work?

Your plumbing system has a backflow prevention device that ensures contaminated water doesn’t back up into your water supply. Backflow testing is the process of inspecting and verifying the function of the backflow prevention device.

Homeowners are encouraged to schedule annual tests to ensure these devices meet local plumbing codes and standards. 

Here’s how our backflow testing process at Day & Night typically works:

Device Shutoff and Pressurization:

The system is temporarily shut off to isolate the backflow preventer. Test gauges are used to measure pressure levels inside the device.

Valve Testing:

Our plumbers check the internal valves to confirm that they’re holding pressure and blocking reverse water flow.

Performance Report:

 If everything checks out, you’ll receive documentation as proof of compliance with local standards. If we find an issue, we’ll help you schedule a sewer line repair or replacement.

These tests are quick, non-invasive, and critical to maintaining the safety of your water supply. With regular testing from our team of certified plumbers, you avoid the risks of contaminated water and potential plumbing failures.

Why Backflow Preventers Are Important

Backflow preventers act as your home’s final line of defense against contaminated water. These devices are installed at key points in your plumbing system to stop dirty or unsafe water from flowing backward into your clean water supply.

When water pressure drops, whether it’s due to a main break, fire hydrant usage, or internal plumbing failure, there’s a chance for cross-connection. That’s when used water, carrying everything from lawn chemicals to waste, can be sucked back into your drinking water system.

A functioning backflow preventer blocks this reversal instantly, protecting your household from serious health risks. It’s often required by local municipalities, especially for irrigation systems, water heaters, and homes with older plumbing.

If you’ve never had your preventer tested, or if you’re unsure it’s working correctly, contact our team of qualified plumbers to receive comprehensive backflow testing services in Phoenix, Arizona along with the surrounding areas. We will ensure your drinking water is safe and inspect your plumbing system for issues.

Top Signs You Have Backflow Issues

Backflow problems don’t always show up as a dramatic plumbing failure. Often, they creep in with subtle warning signs that signal something is wrong behind the scenes. Knowing what to look out for enables you to be proactive about the problem and helps you know when it’s time to give our technicians a call.  


Here are the top indicators that it may be wise to schedule a professional plumbing service with our team at Day & Night:

Leaks

Unexpected water pooling around fixtures or appliances can indicate a potential problem. While leaks can come from worn pipes or valves, they may also indicate pressure changes linked to backflow issues.

Slow Drainage

If sinks, showers, or tubs are draining more slowly than usual, it could mean water is backing up inside your system. Backflow can restrict proper drainage and disrupt normal flow patterns throughout your home.

Low Water Pressure

Your water pressure should remain consistent with little to no fluctuations. When dirty water tries to enter clean lines, it can cause pressure fluctuations and valve issues. 

A sudden or gradual drop in water pressure might signal a backflow problem. Fortunately, our team offers trustworthy backflow testing and repair services for local residents in Phoenix and other locations. Once our certified plumbers arrive at your property, we will check your pipes to confirm the source of the low water pressure and confirm if you have backflow issues.

Poor Water Quality

Water that tastes metallic, smells off, or appears dirty or cloudy is a major warning sign that you could have a backflow issue on your hands. Backflow can introduce harmful substances into your drinking water, affecting its safety and clarity. 

If you notice odd smells or tastes coming from your water, our team of skilled plumbers in Mesa, Arizona and the surrounding areas can help get to the root of the problem so your water tastes fresh again.

Discolored Water

Brown, yellow, or reddish water may indicate rust, sediment, or even worse contaminants that have been pulled in through a backflow incident. This is especially common after pressure drops or plumbing repairs.

Foul Odors

Unpleasant smells coming from faucets or drains are often linked to bacteria or chemicals entering the water supply. A malfunctioning backflow preventer may allow foul-smelling contaminants to flow back into your pipes.

Visible Particles in Water

If you notice debris, dirt, or unidentified particles in your tap water, it could be more than just sediment buildup. Contamination from a backflow event is a serious concern and requires immediate, professional attention.
