| | Palmer's Plastics - Rip Plug Test Solutions Plumbers from all states across the U.S. (provinces in Australia and Canada) that test their DWV lines need to know about the Palmer's™ Rip Plug. Using knock-out plugs inside a Clean-Out Test Tee is against the code, as part of the knock out plug rim is left in. The Palmer's Test Tee Plug is completely removed. Blow up balls are expensive to plumbers because you have to depend on your apprentice plumbers to take good care of these inflatable balls. http://www.ripplug.com |
