Backflow Prevention Services in Sterling
Complete Backflow Preventer Installation, Testing, and Certification in VA, MD, DC
Backflow preventers are critical for safe, uncontaminated drinking water. Without them, your home’s water supply would be contaminated and undrinkable. As the name implies, backflow preventers ensure your water flows in one direction and not in the reverse direction. If the water were to flow in the opposite direction, then it would contaminate the water supply system where you get your drinking water from. Contaminates could include human waste, fertilizers, chlorine, soap, and bacteria, all of which can threaten the health of you and your family.
That said, backflow preventers are absolutely essential to your home. You need a tested and certified backflow preventer device connected to your residence’s water pipes to allow water to flow in one direction and subsequently prevent water contamination, whether you use a well or irrigation system. That’s what we’re here for! Our experienced plumbers at Donmar Heating Cooling & Plumbing are backed by 30+ years of experience and have a reputation for getting the job done right the first time, every time.

What Causes Backflow?
Backflow occurs when water from the main water supply line flows in the opposite direction than it should. Water should only flow into your home, but when backflow occurs, water can flow backward and seep back into the main water supply line.
So, what causes backflow? Common factors include:
- A drop in water pressure
- Broken waters lines
- Significant water use (i.e., for fighting fires)
- Defective installation of an irrigation system
