Backflow Prevention

If you’re not sure whether your building’s backflow preventer is currently certified, you could be putting your employee or tenant’s health at risk. Many things can cause a back-flow situation in your building, creating suction within your building’s faucets. Backflow preventers stop suction from occurring, keeping foreign substances from entering your building’s drinking water. Without this critical yet commonly overlooked component, your building’s drinking water could be polluted with any number of harmful chemicals.

Be Certain. Be Certified.

Knott Mechanical is specifically licensed to inspect and certify backflow preventers. Maryland State Law requires that all commercial backflow preventers be inspected and recertified every year. Is your building up to code? Call 410-561-2000 to find out.
