Backflow is a reversal in water or sewage direction caused by a reversal in water pressure. Contamination can occur from both water and sewerage back-ups, and can originate on your property and from the water supply adjacent to your property.
How Backflow Occurs
Many homes in Connecticut and surrounding states don’t have backflow preventers, but every home should. Here’s how backflow occurs:
- A break in a city water line can cause polluted water and other contaminants to enter the city water supply.
- Line flushing and firefighting can produce the same harmful result.
- Water systems that are supplied by wells or come in contact with untreated or contaminated streams or ponds also create potential backflow hazards.
- A toilet flush valve without an anti-siphon device can permit toilet odors, vapors and worse to get into household plumbing and the water you drink.
- If a garden hose is used to clean out sewer lines or rain gutter downspouts, a drop in pressure can cause contaminants to be drawn back into your water supply.
- Water used to fill a swimming pool can be drawn back into the water supply during pressure drops.
- If an insecticide attachment is used on a garden hose, backflow can cause potentially lethal contamination of water supplies.
Did you know: If you currently have a fire sprinkler system, you already have a built-in backflow preventer. It is also a good idea to install a lawn sprinkler/irrigation system with a built-in backflow prevention. While pesticides may be good for your lawn and help beautify your home, they definitely are not something you want backing up into your home water supply.
