They feature a durable bronze body and a check valve and air opening port in one assembly. A. The backflow preventer is designed to relieve pressure when the watering cycle stops or the system is turned off, so you will see water dripping from it at system shutdown. To troubleshoot leaking of a hose end backflow preventer, the first thing to check is the washer seal in the female connection. The rubber washer will deteriorate or dry out over time and need to be replaced periodically.
HOWEVER...limitation in local authority does not alter the basic requirement for protection of the potable water supply. Installing a backflow preventer outside and above the ground proved to be the best practice. Unlike devices installed below terrain and inside the building , backflow preventers above ground and outside are the best of two worlds. Installing backflow prevention devices outside and above the surface protects property, the environment, testing and maintenance workers, and building inhabitants. In addition, it shields designer engineers from unnecessary liability.

The compartment must have an appropriate locking and drainage mechanism, temperature maintenance capacity, and a strong and rugged structure. Installing a backflow preventer inside an underground vault is an outdated method that is still in use nowadays, mainly because of aesthetic reasons. The problem with subterranean vaults is that they are underground, meaning greater chances of flooding. The sole purpose of backflow preventers is to prevent cross-connections . Subterranean vaults contradict that purpose because they flood, causing cross-connections and contamination.
A backflow preventer is a plumbing device that prevents water from flowing reversely.

The first step in installing a PVB device is to check with the local codes for backflow device requirements and restrictions. The installation site must be easily accessible for routine testing and maintenance to ensure the system is operating properly. Prior to installing this backflow device, the supply line must be flushed with all foreign material. Pressure Vacuum Breaker assemblies must be installed at a minimum of 12 inches above the highest downstream outlet, and the highest point in the downstream piping.
Sprinkler irrigation systems that are supplied by either domestic or private potable water systems have the potential to be pollution hazards to the water supply. According to federal law, it is required that these systems be protected with the installation of a backflow device to protect against possible back-siphonage into the potable water supply. Sprinkler Warehouse encourages our customers to check their local water authority for installation requirements and codes.
Warning About Irrigation Systems Supplied By Domestic Potable Water Systems
Then remove all of the broken plastic parts from inside the backflow device. It is important not to remove the metal piece at the bottom inside the backflow device because it has a spring below it that may hurt you. Finally, you need to place the bell on top of the metal screw and tighten the small nut just enough to hold the metal bell on the device and still rotate by hand with some tension. To avoid having to replace the bonnet and poppet again you should cover the backflow device with an insulated pouch to protect against freezing temperatures.
If you over tighten them, it can ruin the washer seal or cause cracks that will leak as well. Whatever material you choose, ensure it conforms to all applicable safety and health standards. An appropriate enclosure should satisfy draining and temperature standards, as well. Choosing the right size and color will help you meet your design demands. Depending on the size of the backflow preventer, the enclosure can vary.
