Protect Your Water Supply
Clean, uncontaminated water is essential for your family’s health and safety. Even strong plumbing systems can be at risk for backflow, a reversal of water flow that allows pollutants from your yard, irrigation system, pool, or storm drains to enter your drinking water lines.
At B&W Fire Security Systems, our certified backflow testers provide installation, inspection, repair, and certification services that keep your home’s backflow protection working properly and in full compliance with local regulations.
UNDERSTANDING YOUR SYSTEM
A backflow prevention device keeps contaminated water from flowing backward into your clean water supply. When municipal pressure falls, or your own sprinklers or pumps push water too hard, the flow can reverse and bring pollutants such as fertilizers, sediment, or chemical solutions into your drinking water.
Because these risks can be hidden, a properly installed and maintained device becomes not just a smart precaution but often a requirement. You can learn more about Arizona’s official backflow prevention regulations on the Arizona Department of Environmental Quality website.
IDENTIFYING HIDDEN RISKS
Even small plumbing issues can cause a serious problem when water starts flowing the wrong way. Backflow can happen quietly and without visible signs until it’s too late, which is why understanding the causes is so important. Our certified technicians know how to identify these risks early and keep your home’s water clean and dependable.
Pressure loss or line breaks
When the city’s water pressure drops suddenly, such as during a main break, firefighting activity, or heavy water use in your neighborhood, the flow in your plumbing can reverse. This can pull in contaminated water from your irrigation lines, hose bibs, or even your pool.
Excess back pressure
Equipment inside your home, like well pumps, irrigation systems, or heating systems, can sometimes create higher pressure than the municipal supply. When that happens, water is forced backward into your clean water lines, carrying unwanted substances with it.
Improper installation or wear over time
Backflow devices use internal seals and valves that must stay in good condition to work properly. Over time, minerals in the water, corrosion, or general aging can weaken these parts, allowing leaks or failure. Older systems may also lack the proper assembly for your current plumbing setup, leaving your home exposed.
Fixing the Issue
We handle these problems by testing and repairing existing assemblies or replacing them with new, properly sized residential backflow preventers. Our certified technicians follow local regulations and manufacturer guidelines so your home’s system stays compliant and ready when you need it.
What we do
We provide certified testing, repair, and installation services to keep your home’s water system safe and compliant. Every residential backflow preventer we service is handled with care, attention to detail, and a focus on long-term reliability.
Annual testing is the best way to confirm your backflow preventer is working as it should. Our licensed technicians check valve function, seals, and water pressure, then submit certified test reports directly to your local municipality so you stay up to date with all required records.
If a valve fails or your device begins to leak, our team can repair or rebuild the assembly using manufacturer-approved parts. We test each repaired system to confirm proper operation and help extend the lifespan of your residential backflow preventer.
Outdated or noncompliant units can leave your water supply vulnerable. We install new, approved backflow prevention devices sized correctly for your home’s plumbing and designed to meet Arizona and local water department standards.
Keeping your system compliant doesn’t have to be complicated. We walk homeowners through local codes, inspection timelines, and testing documentation so you always know what’s required to stay in good standing with your city’s water department.
