Welcome to the Hessenauer Sprinkler Repair and Irrigation website and blog. Often when discussing irrigation systems, backflow is a topic that may arise or even be the issue, and it is a good idea for homeowners to understand the reasons for backflow testing. Today we would like to give our online readers what we like to call, the downlow on backflow.
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.
Backflow is the undesirable reversal of flow in a potable water distribution system, as a result of back pressure or back siphonage. Just like parts on a car, backflow assemblies and devices can break down and wear out. Backflow assemblies should be tested annually to ensure the drinking water supplied to your home is safe.
Hessenauer Sprinkler Repair and Irrigation has certified backflow technicians certified for inspection, testing, repair and installation of all backflow assemblies and devices.
The first component in your irrigation system is the anti-siphon valve. To understand more about how your irrigation system works, review this post explaining anti-siphon valves and backflow prevention.
Water is brought to your property under pressure from a city main line. The water then encounters a cross-connection, with one water line to the home, and the other for irrigation. Just after this connection, on the irrigation pipe, you’ll find the anti-siphon valve. An anti-siphon valve is a combination valve and atmospheric backflow preventer, which means it serves two functions.
The anti-siphon valve protects the home’s water supply by preventing water in the irrigation system line from back siphoning into your home, and this valve is also responsible for holding pressure for your home’s irrigation system. Water is held under pressure behind each anti-siphon valve. When it receives an electronic signal from the irrigation controller, the valve opens, allowing water to pass through to the sprinklers. Sometimes these valves need to be operated manually to check a sprinkler or if a power outage is experienced. Always trust a licensed professional to handle your irrigation system situations.
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 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.
