Backflow Preventer
A Backflow Preventer is a safety device used in irrigation and plumbing systems that stops contaminated water from flowing backward into clean water supplies. It's like a one-way door for water that protects drinking water from being contaminated by irrigation systems. This is important in landscaping because many states require certified professionals to install and test these devices. When you see this term on a resume, it often indicates the person has special certification and training in water safety systems, which is valuable for commercial and residential landscaping projects.
