We recommend that your backflow device be rebuilt if it has been in service a number of years. Depending on the usage you can rebuild every three to five years. We use original manufacturer parts and can advise you ahead of time when your valve is due for a sophisticated rebuild. Most parts are available even for older backflow prevention devices, however if parts are not available or your device is in poor condition it would require replacing the backflow prevention device.
Every year you should get your backflow device tested. The backflow valve is tested for internal and external conditions. A backflow prevention device failure to operate correctly may be obvious from a visual inspection but with the proper testing equipment performed by a certified backflow tester it can easily be detected. If you have a failed backflow device, you would want it repaired or replaced as soon as possible. Water King Inc is ready to make all your necessary repairs all at affordable prices.
