Sewage Backups Can Be a Health Hazard
Houston’s Top Backflow Testing & Prevention Services
A backflow preventer allows water to flow in one direction — away from your home. If this crucial device fails, contaminated water can back up into your plumbing system. At Village Plumbing, Air & Electric, we specialize in backflow testing to assess how your backflow preventer is working. Whether there’s an issue inside or outside your home, we can quickly take action so the water you use for drinking, cooking, cleaning, and bathing is free of waste, dirt, and chemicals.
What Causes Backflow?
Backflow is when wastewater reverses flow and reaches clean water supply lines in your home. It can happen at any cross-connection in your plumbing system or outside where a sewer line or water main has ruptured. The pressure can be so strong that this wastewater reaches drains, toilets, and other plumbing fixtures and overflows.
The primary causes of backflow include:Â
- Back siphonage:Â Issues with water pressure in pipes can result in backflow. If the pressure in one area is lower than in other parts of your plumbing, higher-pressure fluids can rush into that area. A vacuum essentially pulls water in.
- Back pressure:Â Back pressure occurs when a pump applies pressure to a pipe system. It can also happen when water is suddenly influenced by gravity, such as when a hose is lifted above the ground. A fall in water pressure due to increased demand, a burst water main, or a frozen pipe can also result in backflow.
How Is a Backflow Preventer Tested?
In Texas, backflow preventers must be inspected and tested every year. If not, a home or business owner can face heavy fines. Testing must be completed by a licensed professional.
Our team has years of experience in backflow preventer testing. The testing process involves opening and closing valves in the backflow system while taking pressure measurements. We’ll also determine if a backflow preventer activates when it’s supposed to.
The observations taken can help identify any abnormal changes in pressure that may warrant repairing or replacing your backflow preventer.
