“Backflow” is a plumbing term for any occurrence in which unwanted water flows in reverse, contaminating clean water. It can be a serious problem, causing deadly health risks and possible property damage.
We believe clean indoor air and drinking water are vital to preserving your quality of life. M.E. Flow has served Fairfax, Sterling, McLean, and other Northern Virginia communities since 1951. Our family is invested in keeping your family safe.
What Causes Backflow?
In almost every water supply/takeaway system, water lines cross-connect at some point. During a backflow occurrence, discharged wastewater, gases, and solids can mix with clean drinking water. This can occur in municipal water systems as well as commercial and residential ones.
In homes, a water pressure fluctuation can cause backflow from kitchen/bathroom sinks, dishwashers/washing machines, and even swimming pools. Backflow can contaminate water sources throughout your house.
Common backflow causes include:
- Burst/broken pipes
- Burst/leaking water mains
- Frozen pipes
- Higher-than-usual water demand
Backflow Is Preventable
Your local plumbing professional can recommend the backflow prevention device that is best suited for your commercial or residential property. Types of backflow preventions include:
- Air gap – An air gap is created at the end of your water supply line to maintain positive pressure. This is not always an efficient solution.
- AVB – The atmospheric vacuum breaker is installed at the end of a water pipe to maintain water pressure.
- DCV – Double-check valves have two spring-loaded check valves and a shutoff valve. DCVs are often used for underground backflow prevention.
- PVB – A pressure vacuum breaker can regulate water pressure using a spring-loaded check valve with a shutoff valve. Some PVBs can leak; a spill-resistant device is better.
- RPZA – Reduced pressure zone assemblies are extremely efficient and dependable. Two spring-loaded check valves and an inlet shutoff valve are separated by test cocks, an outlet shutoff valve, and a pressure differential relief valve.
Ask your M.E. Flow plumbing pros what type of backflow preventer will be most effective for your type of property. We’ll explain the safest, most efficient locations for installation.
