Protect Your Water, Stay Compliant
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.

Backflow testing is the process of checking a backflow prevention device to ensure it’s properly stopping water from flowing backward into your clean water supply. It’s a critical part of protecting your home from water contamination caused by pressure changes in the plumbing system.
Backflow testing is required by many municipalities, including McKinney, TX, for properties with irrigation systems, pools, or other high-risk cross-connections. It protects your family’s water from contamination by ensuring your backflow device is working correctly.
Texas law requires annual backflow testing for most residential and commercial properties with a backflow prevention assembly. Your water provider may also send annual reminders based on city code enforcement.
Failing to test your backflow device may result in fines, disconnection of water service, or non-compliance with city ordinances. More importantly, you risk contaminated water entering your home’s plumbing
A backflow prevention device is a mechanical system installed on your plumbing to prevent dirty or contaminated water from flowing back into your clean water lines. It’s commonly used on irrigation systems, pools, and fire sprinkler systems.
A typical residential backflow test takes about 30 to 45 minutes. Our licensed technicians will also handle the required paperwork and submit results to the City of McKinney.
