There are times when foreign objects unnecessarily enter into the potable supply of water. This occurrence is called backflow which can be caused by a greater amount of pressure in one point of use or a negative pressure in the water line. Backflow prevention is essential in keeping the water supply free from any form of contaminants. Any house or building structure should have the proper backflow prevention device to avoid any damages brought on by contaminated water supply. There are numerous devices used in backflow prevention systems. All these devices conduct a similar function yet the kind of devices to be utilized will be based on the water situation to be prevented. The atmospheric vacuum-breaker is a device shaped like an elbow and bent at right angles. A valve placed inside the device is what inhibits the backflow. This system is dependent on the pressure. This device needs to be mounted at a minimum of six inches from where the downstream is located.
A chemigation valve is a device used in agricultural areas. In these agricultural settings, the device functions to keep the water from being contaminated with fertilizers, pesticides as well as other toxic chemicals. Other components exist in the valve. A flapper operated using a spring is present in a check valve that keeps water flowing in one direction. The device could also contain vacuum release and pressure drain. An injection port is the last component of the device which drives the chemicals to go downwards.
A hydrostatic loop is made up of a number of pipes assembling a vertical structure. The loop needs to be placed above 33 feet so that the system will function properly and prevents backflow and siphonage into the water line.
A double-check valve is normally seen in systems like fire or lawn sprinklers. On each end is an assembled gate or valve gate. The device allows testing and isolation. This valve also permits reverse and normal flow.
RPZD is a device used in zones with reduced pressure. This device is very effective in keeping the water supply from being contaminated and it's intended to deal with hazards present in high leveled places. These hazards are known to create serious harm on individuals. There are places where this device has to be tested by a certified technician at least once each year. There's a chamber in between the separate check valves of the device where pressure monitoring is performed. The excessive amount of pressure is going to be taken off through another drain. The chamber where pressure is monitored is retained at a pressure less than that of water supply.
Air gap is a backflow prevention device that's typically found in most homes. In the house's faucet there is an air gap in between the sink and the head of the faucet. On winter season, homeowners are advised to turn on the faucet at night. The flowing water helps prevent it from getting frozen. Frozen and expanded water is probably going to cause the pipes to burst. Pressure can also be relieved as water is permitted to flow to a certain area as pressure starts to build caused by the partial freezing of the water.
