would this work, overflow??

[est 032909]

hellllllooooo,

my current setup on my 75 gallon is a drilled back panel with overflow box.

- 1" bulkhead down to the sump, flexible
- .75" return through the overflow box, which is flexible

i really wanna redo the majority of plumbing and hardware down below, but would like to attack some of the issues i have with this overflow situation.

with the return line running back through the overflow, just below the actual overflow plumbing...and the horrible design of the bulkheads...

when someone does a water change the flow down to the sump stops when it reaches a certain point in regard with the overflow box. in my situation it stops when the water line falls below the return line bulkhead.

yes all my plumbing is tight.

no i'm not siphoning from my locline plumbing.

what i would like to do is remove the overflow box and just continue the overflow pipe straight into the middle of the tank.

same with my return line.

pix for better explanation....

I know it's confusing, but it's such a pain changing the water. Plus, I know that I'd have a serious problem if the power were to go out....

Thanks,
-Brad

Yes your drawing stink. But the idea is sound. and should work as you want it to.

That being said, The stand pix are awesome.

The only problem I see is getting the pump running after a WC.
From your drawing your drain line would empty when water level gets low enough or power goes off.
No pumps I`ve used for a tank had the ability to self prime.
Even with a check valve you could end up with enough air in the line to keep the pump from priming when doing a WC, though the valve would help with a power off situation.
For the drain line you would need a couple more fittings to build a "trap" that would keep the line full when water level goes lower than the suction opening.

If this set-up is draining down into a sump and he does a water change and fills into the sump as soon as their is enough water for the pump to return to the tank it will start circulating. Then as soon as the water is higher then the the strainer in the tank It should just flow back down to the sump.

thanks....

but in regard to the draining issue...

no need to prime. my sump will always have water in it. i've been having problems with potential overflow of the sump.....just with water changes!

i couldn't imagine a power outage...the leaking bulked is maybe 3 inches below the water line. that's almost 11 gallons of water in my sump, and it's one of the smaller ones. !!!!!!!

i would like to come off the back glass to potentially the middle of the tank into an elbow and put some sort of strainer on the end to cut down on noise.

thanks for the input everyone,

there is always air in the drain line. it's not a spihon nor would i want it that way.

for there to be no air in that line the entire room would have to be filled up with water. the tank, the stand, the sump, my apartment. loll.

Sorry All,
Major brain fart..
You are all correct about the drain line.
Have a project in the still working part of the grey matter that snuck out and contaminated my post.
