Backflow testing is a process of checking the water pressure in a building’s water supply to ensure that it is strong enough to push water up and out of the building, instead of allowing it to flow back down into the water supply. Tests involve using valves on a backflow testing device.
Backflow can potentially contaminate a building’s potable water supply with harmful bacteria, chemicals, or other pollutants, so it’s important to have regular backflow testing to ensure the safety of the residents and staff.
