Backflow

Plumbing is the foundation of every good irrigation system. The main tie-in, if not done right, can carry the potential for disaster.  Flooded basements, washed out foundations, and huge water bills can result if the work is sub-par.  Backflow Prevention is critical in protecting your family and neighbors from possible contamination.  Every County has specific guidelines as to the approved Backflow prevention devises and how they are to be installed.

You may be required to have your Backflow tested annually. If so, we have a Virginia State certified and licensed Backflow Technician on staff. To schedule a Backflow Inspection call the number below, or use the form. We will call you back within 24hrs to schedule your appointment.
