Kalkwasser Reactor in 20 Steps
Step 14
Install the  4” T Plug PVC (thread) into the  4” FIPT Adapter PVC (slip/thread)
* Do not over-tighten at this point.
Step 15
Attach the 4” Hub Closet Flange ABS to the 4” S Cap PVC (slip) using a generous amount of silicone.
* You can also use PVC cement, although the Closet Flange is ABS. The silicone will set and securely attach the pieces.
Step 16
Set the entire assembly aside to dry overnight. This will insure that the silicone sets sufficiently.
