First dual overflow tank

rffanat1c · 12/16/2017, 01:38 AM

Hey all, filling up my 180 tonight and it is 1/8” off left to right. The right overflow is full and draining into the sump but the left one is empty. I have read this is an acceptable amount over 6’ but will my left overflow have water in it once the sump is full??

If it doesn't it will when the pump is on and you probably won't notice the difference.

As long as your pump builds more than 1/8" of head in the display then both will function.

My dual overflow was off, and I emptied tank and leveled it.

Both overflows are functioning just fine after turning return pump on. Thanks all.
