The NMB Stopper with Indicator (SWI) is designed to be placed in the grout outlet tube opening. The stopper inserts tight into the PVC outlet tube (14mm). Stopper allows air and water to pass the indicator but when solid grout arrives, it pushes the plunger against the stopper and seals off the tube.
