Aquatherm North America and McElroy have made available the Polypropylene Hot Tap Tool for exclusive use with Aquatherm polypropylene random (PP-R) pipe and fittings. Previously, a new branch line would require shutting down and draining the piping system. This new tool allows the installation of branches to a live service line, eliminating service disruption. The patent-pending design completely seals the system, drills through the pipe wall and retracts cutout pipe pieces, leaving in place a fusion-welded outlet fitting and ball valve. It is designed to provide branch lines ranging from 1- to 2-inch-nominal diameter on Aquatherm PP-R piping systems. The hot tap outlet can be used on main pipes that are at least twice the nominal size of the branch line.
