To prevent backflow in your plumbing system we can utilize a simple and effective strategy of creating an air gap. This backflow preventer is an open space (often a vertical area separating the flood level and water outlet) that occurs between devices that connect a plumbing system, such as a faucet or valve, to a location where water is likely to pool.
Our customers are our top priority. We want to make sure you get the service you expect and more!
Our same-day service is one of our popular requests!
In situations where an air gap is not the right alternative, we will suggest a backflow prevention device. A backflow preventer valve can be installed throughout the plumbing system anywhere that has a high risk of potentially contaminating the water supply.
