Back Flow Prevention - Inspection Service

backflow valveA backflow prevention assembly is used to protect water supplies from contamination or pollution.  In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower etc. When pressure fails or is reduced as may happen if a water main bursts, pipes freeze or there is unexpectedly high demand on the water system, the pressure in the pipe may be reduced and may allow contaminated water from the ground, from storage or from other sources to be drawn into the system.

Back pressure is another way that an undesirable contaminant may enter your potable water piping. Sources of back pressure may be pumps in the water distribution system, boilers or heat exchanging equipment and even power washing equipment. In these cases you may have an almost constant risk of overcoming the static water pressure in the piping and when chemicals are used, as they are for commercial/industrial descaling (boilers) or residentially as in deck/siding cleaning such as bleaches (power washing), you would benefit greatly from having a backflow preventer.
