Back-siphonage happens when a sudden drop in water pressure, often from a break in the water main nearby or heavy demand elsewhere in the system, pulls water backward through your fixtures instead of forward as usual. Where there’s a cross-connection nearby, that reverse flow can pull contaminants directly into your home’s drinking water before you’d have any way of knowing.

A cross-connection is any direct or indirect link between your potable water piping and a source of contamination. It can be as ordinary as a garden hose left sitting in a bucket of cleaning water, a pool, or a pond, situations most homeowners wouldn’t think twice about. We’re trained to identify and eliminate these risks throughout your property, both indoors and out.
