How It Works
Line taps, also known as hot or wet taps, provide access to a pressurized pipe without disrupting pressure or service upstream of the tap. A pressure tap is first made by installing a sleeve that is capable of retaining the internal pressure of the water main around the pipe, such as Hydra-Stop’s Insta-Valve insertion valve or HSF 250 line stop fitting. A temporary gate valve is attached to the sleeve, through which the tap is performed.
