Ghost overflow question

[kattsue]

I put water in my display to start cycling tank but not high enough to start flowing into overflow box. When I woke up this morning there was water in the back of box dripping into sump from bottom of emergency pipe where it connects to box. Stupid question I know but how did water get into back of box but not going through bulkhead.

probably leaking through the bulkheads..

Where did you place the rubber washer? (Id expect 2 actually per bulkhead).. one on each side directly on the glass surfaces between the box and glass on each side

[kattsue]

There are 2. One on each side.

There are 2. One on each side.

Well.. could be dirt, a little flash/burr from manufacturing,etc.. in there or bulkheads not tightened properly,etc..
Its just going into the external box so I wouldn't worry about it personally..

Now if its leaking on the floor then I'd do something..

I drained some water to make sure gaskets on right and they are. Don't see any water dripping on floor. Guess I'll keep an eye on it. Thanks
