Protect Your Drinking Water with Professional Backflow Testing

Did you know that water in your home can flow in the wrong direction and contaminate your clean drinking water supply? That’s called backflow—and it’s more common (and dangerous) than most homeowners realize.

At Smith and Son Plumbing, we offer licensed Backflow Testing and Installation services in McKinney, Texas to help protect your family and ensure compliance with state and local plumbing codes.

What Is Backflow—and Why Should You Care?

Backflow occurs when water flows backward into your home’s clean water system due to a sudden change in pressure—often caused by irrigation systems, water main breaks, or plumbing system malfunctions.

When this happens, dirty or contaminated water (including fertilizer, pesticides, or even sewage) can enter your home's water supply. Backflow prevention devices are designed to stop this from happening, but they must be tested annually to ensure they're working correctly.

Why McKinney Homeowners Need Backflow Testing

McKinney’s growing population and widespread use of sprinkler systems, pools, and irrigation setups make backflow prevention essential. Here’s why testing matters:

Backflow Testing Is Legally Required in Texas

Many residential and commercial properties in Texas are legally required to undergo annual backflow testing, especially those with sprinkler systems, irrigation setups, pools, or fire sprinkler systems.

This regulation is enforced by both the Texas Commission on Environmental Quality (TCEQ) and local municipalities like the City of Plano. Regular testing helps ensure your property remains up to code and avoids fines or water service disruptions.

Prevents Contamination of Your Drinking Water

A functioning backflow prevention device is critical to keeping your home’s drinking water safe from contamination.

Without it, harmful substances like pesticides, fertilizer runoff, or sewage can backflow into your clean water lines due to sudden pressure changes. Annual backflow testing ensures your device is actively protecting your family’s health and your home’s water supply.

Protects Your System After Weather Extremes and Heavy Use

Over time, backflow preventers can fail due to debris, mineral buildup, and wear caused by weather extremes—especially during Plano’s hot summers and freezing winters. Devices may also degrade after frequent usage, such as with active irrigation systems.

Backflow testing helps catch these issues early, giving you peace of mind and preventing costly emergency repairs down the road.

Ensures Compliance with Local Water Department Regulations

Cities like McKinney, require homeowners and business owners to submit proof of annual backflow testing to their water departments. Staying in compliance helps you avoid citations, fines, or delays in property sales.

At Smith and Son Plumbing, we make it easy by submitting all required test results directly to the City of Plano on your behalf.
