| Common types of backflow prevention devices are air gaps. Air gaps create space in your water storage area which connects your plumbing system and a check valve, which prevents water from flowing backward into your home by only allowing water to flow in only one direction.
American Lawn Sprinkler specializes in testing Backflow Preventers of all types and sizes of irrigations systems.
For more information please call American Lawn Sprinkler Company, your certified backflow tester. |
