Vacuum breakers for outdoor faucets are an essential addition to any home's plumbing system. These devices prevent contaminated water from flowing back into the house's potable water supply. They work by allowing air into the pipe when the water supply is turned off, breaking the vacuum and preventing backflow. This is especially important for homes that use pesticides or fertilizers in their gardens, as these chemicals can be harmful if ingested. Installing a vacuum breaker is a simple and cost-effective way to protect your family and ensure that your water supply remains clean and safe.
