Have you ever wondered what keeps your drinking water safe from dirty water in your garden hose, sprinkler system or sewer lines? This is a picture of a backflow preventer we installed at a home in Stevensville today.
What it Does: Normally, water pressure pushes clean water from your city supply into your home. But if there is a sudden drop in pressure (like a water main break or fire hydrant use) it can create a suction effect. This is called "backflow". A backflow preventer acts as a heavy duty one-way valve that slams shut the moment water tries to flow backward, keeping contaminants out of your tap water.
