Backflow testing checks if your backflow preventer works correctly. A state-certified tester measures water pressure at the device's test ports. This process ensures contaminated water cannot flow backward into your Dallas drinking water supply.

Texas law requires annual backflow testing for:

• Irrigation systems with fertilizer injectors or chemical connections
• Commercial properties with fire suppression or industrial water uses
• Homes with pressure-type backflow preventers installed on main water lines

Our certified testers complete the inspection in 15 to 30 minutes. We file passing reports directly with Dallas Water Utilities. If your device fails, we repair or replace it within the required 10-day window.

Backflow happens when water flows backward through your plumbing. Dirty water from sprinkler systems, hose bibs, or outdoor faucets can reverse direction. This contaminated water enters your home's clean drinking water supply.

Your backflow preventer contains check valves that stop reverse flow. These valves create a one-way barrier in your water line. When pressure drops in the main water line, the valves close automatically. This prevents fertilizer, pesticides, or chemicals from reaching your kitchen and bathroom faucets.

Dallas homes with irrigation systems face the highest risk. Your sprinkler system mixes water with lawn fertilizer and soil bacteria. Without a working backflow preventer, this mixture can flow back into your pipes. Annual testing confirms your device still protects your family.

We test backflow preventers throughout Lakewood, Oak Lawn, and surrounding Dallas neighborhoods. Our certified testers check every valve and pressure point. You receive documentation that your drinking water stays safe all year.

Texas Health and Safety Code requires yearly backflow testing for all regulated devices. The City of Dallas sends annual reminders to property owners with registered backflow preventers. You must use a state-certified tester to perform your inspection.

Our certified plumbers check your device's test cocks, relief valve, and check valves during testing. We measure pressure at multiple points to confirm proper operation. After your device passes, we file the required report with Dallas Water Utilities. This filing satisfies your annual compliance requirement.

Devices that fail testing must be repaired within 10 days of the failed test. We complete repairs and retest immediately to keep you compliant. Properties throughout Preston Hollow, University Park, and all Dallas neighborhoods must follow these testing requirements. Missing your annual test can result in city fines or water service interruption.

Our licensed plumbers install backflow preventers according to Dallas city codes and ordinances. We place your device above ground where testers can access it easily. Proper installation height prevents freeze damage during Dallas winter cold snaps. The device stays visible and reachable for your annual inspections.

We select the correct backflow preventer type for your specific water use. Irrigation systems require different devices than fire suppression lines or chemical feeders. Installing the wrong device type causes failed inspections and compliance problems.

Every installation includes a full pressure test before we leave your property. We verify all valves operate correctly and seal properly. New installations in the M Streets, Uptown, and throughout Dallas require city inspection approval. Our plumbers schedule and coordinate your city inspection to complete the permit process. You pass inspection the first time with no callbacks or corrections needed.

Water leaking from your backflow preventer's test cocks or relief valve means internal parts have failed. You may notice constant dripping or small puddles around the device. These leaks waste water and signal that your preventer cannot protect your drinking water supply.

Reduced water pressure to your sprinkler system or outdoor hose bibs indicates valve problems. Your backflow device may partially close when it should stay open. Older devices develop corrosion and mineral deposits that restrict water flow.

A failed annual test inspection shows your device no longer functions properly. Our testers find worn check valves, stuck relief valves, or pressure imbalances. Dallas hard water accelerates mineral buildup inside the valves. This buildup prevents proper sealing and causes test failures.

Backflow preventers older than 10 years often show visible wear and corrosion. We frequently repair devices in Highland Park and Greenway Parks homes due to age and hard water damage. Our plumbers restore full water pressure and ensure your device passes next year's test.

All properties with underground irrigation systems require backflow prevention in Dallas. Your sprinkler system connects to your home's drinking water supply. Fertilizer injectors and chemical feeders create contamination risks that need protection.

Homes with chemical feeders for swimming pools or lawn treatment systems need backflow devices. Commercial buildings with fire suppression systems must install approved preventers. Medical offices, dental practices, and healthcare facilities require backflow protection due to specialized plumbing connections.

Restaurants and food service businesses throughout Dallas need these devices to protect public water supplies. Multi-family properties and apartment buildings in Dallas proper must install backflow preventers on main water lines.

Not every home requires a backflow device. Our plumbers evaluate your property's plumbing setup and water uses. We determine exactly what type of protection your Dallas property needs. Commercial spaces in Deep Ellum and the Design District often need multiple devices for different building systems. We assess your requirements and install only what city codes require for your specific situation.
