User Guide

NB. All cylindrical stoppers must be inflated to the prescribed pressure and suitably strutted or braced to prevent movement under pressure. It is essential to release any back pressure from the pipe before attempting to remove the bracing. Stoppers should not be used in unsound, uncovered, excavated or unrestrained pipework!

Note: Stoppers must be fully inserted into the pipe prior to inflation and must not be used in pipework within open excavations or unrestrained pipework. All pipes must be anchored before pressure testing
