Danboise Mechanical, Inc. | Backflow Testing

A backflow, which is also known as a cross connection, is any connection between piping that carries drinking water (also known as potable) and the piping or fixtures that carry other types of water or substances that are not safe to drink (also known as non-potable). The backflow can occur when material moves from the contaminated source back into the drinking water system.

Did you know that lawn irrigation systems, swimming pools and hot tubs are common cross connection points? When the sprinklers on irrigation systems are nested underground, it is possible for contaminated water to flow into the sprinklers. In swimming pools and hot tubs, if water inlets (the points where water flows into the pool or tub) are submerged, it is a cross connection. This often occurs in hot tubs with submerged inlets that are made of permanent hard piping.

The Michigan State Plumbing Code requires you to have all of your building backflow prevention devices tested and re-certified annually.

Danboise Mechanical is pleased to offer a full service team of State Certified Cross Connection Specialists trained in installation, replacement, repair, and re-certification.
