Urgent: Overflow leak.. Advise required.

[JDigital]

Scenario 2, 99.9% won't happen, as I had a slight oversight when doing my plumbing and cemented the stand pipes into the bulkheads. I left that .1% so I don't sound like a fool in the future when my PVC cement fails me for the first time ever..

That leaves your first scenario, which is possible. But I think if the bulkheads themselves leak, it would be manageable to replace them with the aid of a towel so soak up any leakage while replacing. A possible nuisance for sure, but manageable and easy to keep check of on a daily basis. I shouldn't say this, but I have always had good luck with bulkheads not leaking.

The leak is fairly slow.. over the course of 1.5hrs the level in the overflow raised by 1/8" (in a 8.5"x6" footprint).

If power goes out you DT will be still draining in to the Overflow and down to the sump. If your sump is larger then DT you are ok.

But skimmer will overflow as well as whatever else you have in the sump

Find yourself a tube of Orca Glue. It seals underwater and it's safe.

Works like a charm and has saved me countless times

I had a small leak in one side of the overflow in my 180g once. The only problem I thought it may be was as mentioned, seeping between the stack and bulkhead portion during long shutdowns, for whatever reason. I sealed the stack with plumbing tape and it was fine. If you glued yours, thats even better.

I dont see how it can run into the sump any different than normal in that case?

I must say, it always did bug me though, thinking it could all leak out somehow.
