Commercial Backflow Testing Services

TLC has a dedicated team of plumbers who are certified and experienced in commercial backflow preventers. We test, repair and replace all types of commercial backflow systems. Businesses may have more than one system for different types of water it is important to hire a plumber that is certified and experienced in commercial backflow assembly system testing.

  • Domestic Water Backflow Preventer – This type of system prevents backflow for water that is used in a building for normal everyday water.
  • Fire Suppression Backflow System – A fire suppression backflow system is designed to keep a building’s fire sprinkler system pressurized and ready in the event of a fire. This system needs to be tested annually to make sure that the system is holding water pressure.
  • Irrigation System Backflow – If a commercial property has an irrigation system then a backflow assembly valve is required for this water source. Irrigation systems usually use non-potable water and require a backflow system to keep this water out of the municipal water supply.

Our plumbers are here when you need your backflow testing and repairs.

TLC Backflow Testing Process

1) Schedule An Appointment

When you receive your notice for your annual test call us at (505) 761-9644 or schedule online. We will schedule one of our backflow certified plumbers to perform your test.

2) Perform Your Backflow Test

Our backflow tests typically take about an hour to complete unless there are other issues with the backflow system.

3) If Backflow System Passes Inspection

If the clog is unable to be cleared with the cable machine, our professional plumber will use a line with a specialized camera on the end to view the inside of the drain and locate the problem. At this point, the drain tech will describe the problem and give you options for hydro jetting, descaling, or a possible sewer line repair to fix the problem.

4) If Backflow System Does NOT Pass Inspection

If your backflow prevention system does not pass inspection our plumber will notify you and attempt to repair the backflow. If the unit cannot be repaired it must be replaced. TLC is qualified and experienced in backflow repairs and replacements. Once the repairs have been complete TLC will perform a second test to make sure the system passes the test.
