Backflow services

Backflow is a movement of dirty water in the reverse direction through clean water lines. In the normal plumbing process, potable or clean water flows under pressure through municipal water lines to your businesses. Having clean water entering your commercial property is imperative for a properly functioning plumbing system. A backflow of dirty water can be contaminated with hazardous materials such as fertilizers, pesticides, chemicals, feces, and other toxins.  This can cause serious health hazards if left unchecked. Backflow can occur at any cross-connection point between potable and non-potable water in the plumbing system and can cause damage to your business as well as your plumbing system.

Backflow problems usually occur when pressure in the sewage lines is increased, the pressure in the water lines is decreased, or at any points where the two lines cross. Other causes include pipe freezes, water main breaks, or high water utilization. To prevent backflow, a number of precautions are taking during construction.  This includes separating water and sewage lines, adding simple check valves to check for air gaps, and the installation of backflow prevention devices.

Backflow prevention devices may be required to stay in compliance with municipal code.  The type of prevention device used will vary depending on your location and type of business.  Backflow prevention devices are installed at cross-connection points in your commercial plumbing system. The device generally consists of a pair of mechanical check values that prevent dirty water from flowing back into the clean water supply in the event of an unexpected or drastic change in water pressure. When properly installed and maintained, a backflow preventer will keep drinking water safe. However, you can’t just “set it and forget it”. Backflow valves must be inspected annually to ensure proper operation and to keep your property in compliance with the local code. If a backflow problem or contamination problem occurs, your business may be fined if backflow testing hasn’t been completed. Testing backflow prevention devices is straightforward.  The professionals at NRH Plumbing will turn off the water, test the device and certify its working operation.
