Befour you install a coupling on glass pipe you would.

Apply silicone
Apply plumbers grease
Wet the pipe with water
Dip in oil

I picked wet the pipe with water. Never worked with glass but that made the most sense to me lol iuno if its right

I had that question 2x in my masters. You have to convert litres/minute to fixture Unit to discern the pipe size.

Example : sump pump or rain fall depending on the region for a roof drain.
