Welcome to the Hessenauer Sprinkler Repair and Irrigation blog and website. When sprinkler irrigation systems are discussed, backflow is often mentioned or perhaps an issue. Today we would like to clarify the term “backflow” and explain the functions of some irrigation system backflow prevention devices.
Backflow is the undesirable reversal of flow in a potable water distribution system, as a result of backpressure or back-siphonage. Just like parts on a car, backflow assemblies and devices have can break down and wear out. Backflow assemblies should be tested annually to ensure the drinking water supplied to your home is safe.
Irrigation system backflow prevention devices are designed to protect water supplies from contamination or pollution. They are installed on potable water lines to protect against both back-siphonage and back pressure of contaminated water back into the clean water supply. Backflow assemblies are very important to provide protection where potential health hazards may exist. Knowing some of the basic backflow devices in an irrigation system can make the system easier to understand.
Pressure vacuum breakers (PVB’s) are used to protect water supplies from contamination or pollution by keeping non-potable water from entering the water supply with vacuum pressure. PVB’s usually have specially calibrated gauges to assure they are functioning properly.
Double check valve and reduced pressure assemblies (DCVA) are used to protect water supplies from contamination or pollution. Atmospheric vacuum breakers (AVB) are the simplest design of backflow preventer, and if you have less than six control valves, they are also the least expensive option. Hose-end vacuum breakers attach to the end of your garden hose to prevent running water from re-entering the system.
Backflow repair parts allow you to keep your backflow device, a key part of your sprinkler system, running smoothly. Backflow preventer devices are designed to protect your water system from potentially toxic pollutants, so it is critical to keep them operating properly.
Y-type strainers are recommended for residential and commercial water lines to protect delicate equipment, such as regulators and backflow preventers, by filtering blockage-causing sediment from the water system. Y-strainers are recommended for a variety of water systems, including residential and commercial irrigation and swimming pools.
Backflow theft prevention cages provide maximum strength and safety to keep your backflow device secure. Backflow enclosures are a great way to hide unattractive backflow preventers from view. Backflow enclosures are a great way to hide unattractive backflow preventers from view. They come in a variety of sizes and colors and styles, for all your landscaping needs.
Backflow preventer test kits are compact, lightweight, and portable testing devices. A backflow test kit can be used for reduced pressure zone, double check valve, spill-resistant vacuum breakers, and pressure vacuum breaker backflow preventers.
It is important to maintain a properly functioning irrigation system. To discuss backflow testing, need repairs or have sprinkler irrigation issues to discuss in the Central Florida and Orlando areas, contact us at 407-302-2227 today.
