Technically, best viagra online if one siphons a fluid out of a container or a pipeline, search one causes that fluid to flow up over the rim of the container or top of the pipe and then down into a lower elevation through a piece of tubing or, in this case a piece of pipe that is part of the distribution system. In the vernacular, the unwanted fluid is “sucked” into the potable water line. It is important to understand that it is not necessary for the system main to be under a true vacuum (i.e., zero psia) for backsiphonage to occur. All that is required is a negative difference in pressure and a piece of tubing or pipe that is completely full of fluid.

One of the causes of backsiphonage is a situation that arises when a temporary shutdown of a water main–or an in-plant pipe–becomes necessary for repairs. If the repair is at some point other than that of the highest point in the system, then there will be a potential for a reverse flow if one of the lower points of service is opened while the main valve is closed. Under this condition the water in the internal piping system will drain to the open valve or point of water use, siphoning anything it may be in contact with at the time.
