1.5" drain line. The thingamajig is just a check valve with a union on either end for servicing or replacing the check valve. I thought perhaps there was some back pressure but even with just a bulkhead wide open the tank fills before there is barely anything in the overflow box, for example the tank fills to the point of almost touching the eurobracing before there is anything significant in the overflow box. I just tried again and i quickly started dialing in the gate valve thinking maybe I just had to start a full syphon and nope it stay at about the point of overflowing the display.

The drain line as complex as it may look is not actually that many twists and turns and the ones it does have are made of 2-45*'s and everything has a down sloping angle. I dunno perhaps it is the line causing back pressure.

Yes it was built by concept, I am up for any suggestions!

Yes I do own a dremel great tools! The gap between the teeth is 1/16" which seems really small but what do I know right lol

Ya, if there was a problem with the drain line plumbing I would have expected the overflow box to flood. From your description it sounds like water definitely isn't even getting into the overflow box fast enough.

Those slits sound really narrow to me.

Hey thanks for posting those pics for me! Yea they are only 1/16" as you can see before those pics I drained roughly 15 Gallons out of the display in anticipation of having to somehow widen those slits. When you look at the one photo you can see a scum line from my dry rock of where the water was before I took out the 15 gallons. From that point it raises to almost touching the euro brace and im sure if left it would go over it had it had enough water. At the point of just about touching the euro brace it really starts flowing into the overflow box but by this time it never equalizes and just runs the return pump chamber dry while the display slowly floods.

Whoa, those look really tiny! On the bright side, they look really easy to expand. Just cut a tab out (in between two slits) effectively making larger teeth.

Is the tank under warranty? You could have concepts correct it if it is.

Hi Trevor

Yes we had a run of tanks that had this problem didn't realize at the time the surface tension of water would back up with those size cuts! we figure it would look cleaner but never work out that way

give Denny a call at the shop at 5873237360 and i will have a new panel made up and overnight it out to you


thanks Dave
