A Business Owner's Guide to Backflow
What is backflow?
Backflow is the reversal of the regular flowing direction in plumbing. It occurs at the cross-connection of the plumbing, which connects the potable and nonpotable water supplies. When high pressure created by a malfunctioning boiler or pump pushes water into the area with lower pressure, wastewater and other unsanitary materials can enter the potable water supply.
What are the signs of backflow?
If someone in the office notices that the water tastes, looks, or smells different, there may be contamination. To prevent the spread of illnesses, you should call for backflow testing right away. Also, look out for changes in water pressure, which can signal a backflow issue.
What does backflow testing entail?
Before commercial backflow testing can begin, the water supply to your building will need to be shut off. When the plumbers arrive, they’ll close the gate and relief valves to check for water leaks or changes in gauge movement. Next, a professional will inspect the condition of the valves that prevent backflow. The process usually takes about 20 to 30 minutes, and needed repairs can be performed immediately.
Should I get a backflow preventer?
Yes, a backflow preventer can also ensure that your water supply doesn’t become contaminated. This device is required for many commercial facilities, including restaurants, hospitals, and buildings with sprinkler systems. If you don’t have a backflow preventer, a plumber may recommend installing one during your next commercial backflow test.
