A backflow preventer attaches to the main water line from your home and averts water from flowing back into your home’s pipes and contaminating your clean water supply. It only allows water to flow in one direction, thus avoiding backflow. This is crucial for sprinkler systems and irrigation systems, where water in your yard might carry fertilizers, pest control chemicals, or other contaminants. Backflow preventer device installation is required by law under some circumstances, such as at the source of a sprinkler system, irrigation system, or swimming pool.

Given that sprinkler system backflow preventers are essential for the proper functioning of your irrigation system, it's important to choose the right one for your property. Sprinkler Warehouse's very own irrigation expert Alfred Castillo is here to help ease your decision making and get your lawn on the right track.

Easyflex thermal expansion tanks are designed and manufactured to address the issue of water pressure caused by the thermal expansion of water as it heats up in a water heater. Such pressure can cause damage to valves in plumbing fixtures, joints in supply pipes, and even the water heater itself. Per local codes, a thermal expansion tank is required in cases where the water heater is part of a closed system. A water system is considered closed if a check valve is installed in the incoming water supply, which restricts the flow of expanded heated water from returning to the water main. All Easyflex thermal expansion tanks come with a limited 6-year warranty.

Before selecting a backflow preventer you must research the state and community laws regarding backflow installation types. You should select a backflow device that meets your watering or fertilization requirements. For instance, you may need a single device for a water hose, or one device which will protect an entire irrigation system. Some backflow preventers allow for the safe use of fertilizers in the irrigation system. Each device has a specific use for your unique irrigation system.
