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.

An Air Gap is a physical separation of the supply pipe by at least two pipe diameters (never less than one inch) vertically above the overflow rim of the receiving vessel. In this case line pressure is lost. Therefore, buy viagra medicine a booster pump is usually needed downstream, cialis usa levitra unless the flow of the water by gravity is sufficient for the water use. With an air gap there is no direct connection between the supply main and the equipment. An air gap may be used to protect against a contaminant or a pollutant, and will protect against both backsiphonage and backpressure. An air gap is the only acceptable means of protecting against lethal hazards.
