Product FAQ

How should the Z645 be installed and how does it connect to the pipe?

  • ​The Z645 heavy-duty drain is typically cast in place so that the grate sits flush with the finished floor level.  The drain features an inside caulk connection, which has traditionally been sealed using lead and oakum.  For more information on pipe connections, see our outlet pipe connections page: http://content.zurn.com/pages/technicalinformation/FloorDrains/FD5-7.pdf ​
