Leak testing a sump?

So, I have finished building my 20g long sump. Do I just fill one chamber at a time and check for leaks? Is their anything else I should look for?

Thanks.

 

That's basically it.

If you see a leak, empty it(obviously), let it dry completely, reseal it, wait 24-48 hrs before testing again.

 

Why do you care if it's leaking between panels? Does it really matter? The only leaks that make any difference at all are the external ones (outside glass), as you don't want water on your floor. Tiny (inconsequential) leaks between baffles are nothing to worry about. Annoying? Sure. But to drain it and re-silicone it? I wouldn't sweat the small stuff.

 

Agreed 100% - but if you really want totally sealed- Seano is right.

 

Yup I agree as well ... one of my center baffles had the tiniest leak ... and I thought to myself, why reseal it ... it can't hurt anything, and I've never had a problem with it lol.

 

For example, say you have your return pump submersed(in the sump), then water will evaporate from the return section...If the baffle b/w your return section & the next one is not fully sealed, then evaporation will occur in both sections..

 

You must not have a sump. ;D
The water will be moving through the sump (over the baffles) 1000x faster than the leak between baffles, so trust me, it will never be an issue.

 

i had a leak between the baffles in my 55g sump. i just sealed it off eoth silicone over it and let it dry. small fix to a less important problem.
