I have had this same thing happen with thin PVC, flow to sump plumbing.I checked it every day too! One mystery snail = wet carpet with that system.
How many overflows ? Is it an hob overflow or internal ?I have a 180 and 120 gallon tanks. I wanna starting using a sump which is gonna be 90 gallons. So I'm wondering what size pipe/plumbing I need to use. I'm gonna be doing an overflow to the sump. I already have a 1321 gph pump.
Hey man have you tested the emergency drain ? Depending on how much gph your throwing at the 1.5 durso that emergency may not handle the flow ?I do 1.5 inch durso and a 1 inch stand pipe . The 1 inch standpipe is your fail safe just make it a little taller than the durso. 3/4 inch return.
If you plan to use a pump that is 1300gph with no head, you may not need to go any bigger than 1". But as mentioned above, there are benefits with larger diameter, I wouldn't go bigger than 1.5" for your case. What I noticed is that with larger plumbing, and the pump that isn't comparable, you end up closing the primary drain quite a bit and may defeat the purpose of the larger pipe.I have a 180 and 120 gallon tanks.

Wouldn't you know it? Today for the first time I found a mystery snail in my clear PVC siphon. He wasn't going up and he wasn't going down. He just bobbled there about halfway up the tube to the bend.. . . It doesn't need to be a Mystery snail. . .
