👉 Swallow pipe is a type of pipe that has a conical shape and is used to deliver water from a reservoir or other source into a larger container, such as a tank. It typically consists of two tubes connected at an angle, one for delivering water and the other for venting the excess water back into the reservoir. Swallow pipes are commonly found in agricultural irrigation systems, sewage treatment plants, and many other applications where water needs to be transported over long distances.
