hey guys so i got a dumb question here after setting up my tank and sump ran into a few issues
my piping is all 1 inch id say pretty big?
i have 2x 1 inch lines running down into socks
and 1 emergency line which i have locked off for now
but when i turn my return pump on i have to run it literally on like like 40% power cause its not getting enough water from the drains is this normal?
the pump im using is Amazon.com : Jebao DCT Marine Controllable Water Pump : Pet Supplies
the tank has a flow box built into it with 3 drain lines

am i doing something wrong?

also i need some bulkheads cause the ones i have on the tank are dripping alittle saw some on amazon just dont know if they any good?

Not sure where you are located. I picked up bulk heads in the past from Aquatic Obsessions in Avenal.

If the bulkheads are dripping, tighten them up…and make sure the gasket is on the wet side.

just hand tighten. home depot has gaskets, can try that first. also make sure glass is very clean. some dirt will cause leaks

yah thats my next move is try to replace the gasket without actually taking the whole thing apart cause the guy who had the tank glued it all down with pvc so you cant just take the bulkhead off...

Respectfully, this is not correct. Regardless of how the bulkhead is installed, the gasket ALWAYS goes on the flange side.

The flange side would be in water no? Not sure if anyone would ever have or assume the threaded size would be inside the tank.

I never thought my tank was atypical! :oo:

And here's my atypical sump with a bulkhead for an external pump. I must be special:

Although they are now out of business, anyone with a GlassHoles overflow has flanges outside their tank. My interest in making my statement about gasket location is that I've seen folks installing the gasket on the thread side and wondering why is was leaking. So I still stand by my statement....gasket always goes on the flange side. In your particular application the flange happens to be on the inside of the tank.

I didn’t want to assume anyone was dumb enough to install it that way haha

Flange side, meaning the none thread side no matter if its in or out of the water?

And I guess that’s why they are out of business. Flanges on the outside was their downfall. Jk but as far as gaskets I always assumed they go on wetside guess I should never assume. Just doesn’t make sense to put gasket on dry side.

If you scratch your head and think about it for awhile, it makes sense. The water seal occurs with the flange and gasket flat against the glass. With the flange on the outside, yes, water will creep up the threads, but now stop by the gasket being there. As far as the water seal, a bulkhead will work either way....flange inside or outside. You only need to install dependent on your particular application.
