Bulkhead installation for internal overflow

[Plan2Build]

All,

My question is regarding the installation of my bulkheads inside my overflow (see my previous 90L thread for pictures). :huh:

Would it be necessary or not to put a silicone bead between the sealing gasket and the glass to ensure no water seeps? I do not think it would be needed, but I have heard otherwise.

The gaskets do have 3 "ribs" raised 1mm or less from the rest of the surface....these will be in contact with the glass under compression.......

If anyone can provide their opinion I would appreciate it.

No need for silicone. Just hand tighten the nut on the bulkhead then use a wrench and give it about 1/2 to a full turn.

You will be fine. The silicone will make the surface of the glass slick and when you tighten the nut down, there is a good possibility that the gasket will move around and not make a good seal.

I'll confirm with Mac. I used NO silicon hand tightened my nut, (with rubber gasket inside??) and snugged it up a little bit with a wrench. Never had a drip out of it!!!
