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.

A backflow prevention device is attached to the main water line from your home and prevents water from flowing back into your home's pipes. This is to prevent any contaminants from reaching your drinking water. It only allows water to flow in one direction, thus avoiding backflow. Backflow preventer device installation is required by law under certain circumstances such as at the source of a sprinkler system, irrigation system, or swimming pool.

The unsung heroes of irrigation, backflow preventers ensure that only clean water reaches your home. Our selection of backflow preventer devices features products that stand out for their robust design and innovative features. Choose from our range of reliable sprinkler backflow preventers to ensure a safer, cleaner water supply—because quality water is essential for you and your plants.

Air pressure regulatorhow it works

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.

The Solution Mounting a SaveAir in the air line to help regulate pressure going to the tools will help prevent potential damage to tools and employees. The SaveAir regulates the pressure going directly to the tool at the desired (and recommended) level. The SaveAir will limit air pressure to tools and is available in a variety of pre-set pressures ranging from 15 psig (1 bar) up to 120 psig (8 bar). These pre-set pressure ranges prevent the operator’s ability to adjust or increase the pressure, ensuring the tool is given the optimal working pressure that it was designed for.

Limit Air Pressure to Tools and Workstations The Problem Many workers believe that cranking up the air pressure at their workstations and to their pneumatic tools will help them work faster and more efficiently. In reality, air pressure that is too high can damage the tools, cause them to malfunction or completely stop working. The increased pressure also increases the potential for injury, as well.

By delivering a specific known pressure, the SaveAir® prevents “Dynamic Pressure Waste” that can arise when the pressure and flow are unnecessarily higher (than specified by the manufacturer) at the withdrawal point. Dynamic pressure waste is very costly and difficult to eliminate, but not with SaveAir! This miniature pressure regulator has the outlet pressure preset at the factory. This can be installed before an electronic pressure regulator to reduce P1 pressure, pick and place units in automatic assembly systems or it can be used in automation for actuation devices.

Yes, different irrigation systems may require specific backflow preventers. For example, drip irrigation systems might use a different type of backflow preventer compared to traditional sprinkler systems. It’s important to choose the correct device for your system’s design and requirements.

An AVB requires one unit per valve and most cities don’t allow them in irrigation systems. A PVB is similar to an AVB however it only requires one for the entire irrigation system. The RPZ allows for fertilizers in the irrigation system, a function that no other preventer performs. The DCA allows for the flow of pure water that is not susceptible to contaminants in the air.

Signs that your backflow preventer needs replacement include visible damage, leaking, and failing annual tests. Regular inspection and maintenance can help identify issues early, ensuring protection of your water supply.

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.

The SaveAir regulator is an independent membrane regulator that can be installed in every compressed air system. It supplies a constant, exact outlet pressure regardless of the input pressure. The pressure is factory-set and cannot be changed. SaveAir prevents “dynamic pressure waste.” This arises when the pressure and flow at the withdrawal point are unnecessarily higher than those specified by the manufacturer to achieve the desired function. “Dynamic pressure waste” is extremely costly, a waste of energy that may be found throughout industry.

Irrigation backflow devices are designed for installation on potable water lines to protect against both back-siphonage and back-pressure of contaminated water into the potable water supply. Backflow assemblies provide protection where potential health hazards exist.
