My tank is used and the 3/4" bulkhead is thread x thread (pic attached). I ran my return piping to it and plan to connect to it with a 3/4" male pipe adapter (another pic). I plan to cement the 3/4" pipe to the male pipe adapter. Do I then cement the 3/4" male pipe adapter to the inside of the 3/4" bulkhead? Or should I use something else like plumbing tape? I think I read a lot of people have leaking issues with the thread x thread bulkheads - so I was considering just cementing it.
