Recently glued 2 PVC couplings to a 2" PVC SCH 80 pipe, the couplings were probably SCH 40, but I assumed it would be fine as the pipe is a drain pipe from an Aquarium, so it's not really under any pressure, it leads into a body of water below in the sump.
However, today while running the system, I noticed 1 of the couplings has the smallest little drop of water every few minutes or so. Would it be safe to just silicone from the outside and call it a day, or can that little drip of water eventually lead to the coupling coming apart? The rest of the same coupling is completely dry, I really don't know how it could have happened.
Opinions?
Thank you
