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.

For theft prevention and replacement hassles, our plastic disposable cup will not get stolen. The Palmer's™ Rip Plug will still be holding psi pressure when you return to the drainage waste & vent inspection. Inspectors will feel confident that their ABS or PVC plumbing pipes will hold a pressure test over an extended period of time.

Palmer's® Plugs will save you time & money when testing your ABS or PVC drainage lines ...period.
