Sump issue??

LT43 · Nov 30, 2019

My DT is finally fill of RO/DI water and it’s making its way down into the sump. The first chamber is filling, the second chamber (very narrow baffle prior to the first set of socks) is also filling from the bottom as it should, however the third chamber (first sock chamber) is also filling from the bottom? I don’t see any cracks or issues with the silicon but in my mind this chamber should be filling from it coming over the top? The water level is about an inch lower in the first sock chamber than the other two.

Pictures of your sump and plumbing?

I sucked out all the water from the first filter sock chamber and found the culprit, appears to be a small leak in the corner. Suggestions? In the picture it’s that corner closest to the camera.

Some reef safe coral super glue on each side seems to have stopped it.

Good on you for noticing this. While disappointing, I don't think this leak poses a significant problem, IMO. In normal operation, there is no significant pressure on that wall. On shut down, it is not enough water to make a difference in the rest of the sump even if it leaks.

If it still bugs you, dab some (reefsafe) silicone, let it cure a bit, and fire up the RO again.
