The new Grip Tip Total Knockout Test Plug from Sioux Chief Mfg. is a multiple-feature, cost-effective solution for end cap and test plug users. The Grip Tip has two tips that allow the DWV system to be air or water tested. All plumbers, whether they test with air or water, will find the Grip Tip a time and money saver. Even in markets where DWV testing is not required, the Grip Tip makes for a perfect debris cover that always knocks out in one piece. The Grip Tip can be installed in all Sioux Chief Smart drains and won't prevent installation of p-traps on 1-1/2" DWV. The Grip Tip eliminates the need for separate end caps and test plugs.Sioux Chief Mfg.
