Keeping Water Clean

So, what is backflow? Backflow is a situation that can occur when water pressure in a plumbing system falls below atmospheric pressure. This can cause water to flow backward, or ‘back up,’ into the system. Backflow can contaminate drinking water supplies and present a serious health hazard. It can also cause damage to plumbing fixtures, appliances and equipment. That’s why a backflow prevention device is essential. But they require annual testing to ensure they’re operating as they should. That's where we come in. 


At Dunnrite Plumbing Services, we provide backflow inspections and testing for homes and businesses throughout the Whitsundays, including Airlie Beach, Cannonvale and Proserpine
