👉 A siphonless pipe is a type of pipe that has no valve or other means for controlling flow, allowing water to flow continuously. This feature makes it ideal for use in systems where pressure and volume are not critical factors, such as irrigation systems, industrial processes, and household plumbing. Siphons are typically made of metal or plastic and are used to transport water from a source to a sink or other location. They can be fitted with valves that allow the flow to be controlled by hand
