Scheduling a Cross Connection Survey

A preliminary onsite meeting will be required to provide a written quote for the work. Once approved, an inspection is scheduled with the customer and arrangements are made for an escort with knowledge of the water distribution system. The escort ensures that any questions that arise concerning the water system can be answered expeditiously. During the inspection the waterlines will be located along with any auxiliary water supplies. A review of any contaminants liquid, solid, or gaseous will be evaluated to determine the degree of hazard as it relates to the water system. The specialist will review the equipment that may require internal backflow protection such as but not limited to boilers, cooling towers, chemical dispensers, laboratory equipment, clean room equipment, fire sprinkler systems, irrigation systems, recycled water, etc. Where a hazard to the potable water system has been discovered, you will be required to make corrections or install a backflow prevention device at any/all service connections.
