What happens here
Install a backflow prevention device on the main water line before it connects to the sprinkler system. This device is crucial for preventing contaminated water from the sprinkler system from flowing back into the potable water supply. The specific type of backflow preventer and its installation height (e.g., 12 or 18 inches above ground) depend on local codes and the terrain's elevation changes. This typically involves connecting galvanized pipes with Teflon tape and joint compound, then transitioning to PVC for underground runs. Ensure it is installed correctly to pass inspection and prevent water contamination.
Goal: Prevent backflow of irrigation water into the potable water supply.
