Compression gasket install, cutting oil with dawn, try a compact
Tool Tips—July 2014
When installing a no-caulk shower drain, I found the best way to install the compression gasket is to use a 2-in. PVC coupling and a rubber mallet. When you’re ready to hook up the no-caulk shower drain, place the 2-in. coupling on top of the compression gasket. Lightly hit the top of the coupling until the gasket is in the desired position. Then tighten the compression nut for an even, tight fit. I guarantee this will not damage the gasket and you will have a no-leak seal every time.
