What Is Backflow?
Water should only move through your pipes in one direction—from the main water supply into your home and then out again. But pressure changes in your pipes can occasionally cause water to flow backward. This is dangerous because the water coming back into your home may have come in contact with contaminants like:
How Does a Backflow Preventer Work?
Backflow preventers are designed to block any water that travels through your pipes in the wrong direction. You can think of a backflow preventer like a gate inside your pipes and only moves away from your home. The backflow preventer opens in one direction to let water move freely in the correct direction, but it will not open in the opposite direction, preventing water from moving backward.
Do I Need a Backflow Preventer?
Most homes are not legally required to have a backflow preventer, though some municipalities do require them. Regardless of whether local code necessitates it, however, we recommend installing a residential backflow preventer in any location that cross-contamination between incoming drinking water and wastewater could occur. Residential backflow devices should also be installed at homes that have a well or an irrigation system.
When Do You Need Backflow Prevention Testing?
Because backflow preventers are a health and safety measure, they need to be tested regularly to ensure proper performance. Most residential backflow preventers require annual testing. You should also schedule backflow testing if you notice signs of backflow in your home, such as:
- A change in the taste, color, or smell of tap water
- Pressure changes at one or multiple faucets
- Visible rust or sediment particles in your tap water
