I'm not following? The E-drain should be "taller" than the primary. When all things are up and running, the primary has the full siphon. The E-drain will only have a trickle. So the E-drain is essentially at the water level or slightly under.

If you over fill during a wc and the water gets above the E drain does it level off when you start the pump up ?
For WC, I usually fill up the tank directly until it reaches the same level as after I turned off the pump and the water had drained to the sump. This is also the lowest point of the teethe of the overflow wall. The water in the overflow at this point is still at the level of the main drain.
When you turn the pump back on, the tank will refill back up with water from the sump. Eventually the overflow will "equal" out when the drain is fully siphoning.

Emergency drain test successful but I can't say for sure. It did NOT run on a full siphon (thankfully) and the water level stopped at a certain level. Turns out it was just my paranoia that was holding it back. the reason being is that my overflow box is REALLY high up in the tank. The tank is maybe a few millimeters from the brim but the drain is working. Trust me, it's not fun tearing down your tank and scraping nasty mushrooms with a combat knife for a month if the tank floods and the water gets trapped under the stand and mildews. And I know this is common but I HATE fungi.
Glad it worked out.
So you could cement or glue the standpipe and couple it to a smaller peice. Then cut that peice if need be ?
I never understood this. If yoyr removing the water from the sump at some point doesnt the water level in the tank fall below the oeverflow. Dont you have to remove the water from tank ?
You can adjust the pipes with couplings, yes. But I recommend doing it right the first time. And as for your second, the sump shares the same water volume with the tank, I turn off the return pump before doing so though.
But as your draining water from the sump doesnt the level in the tank eventually fall below your overflows, then only drain from your sump ? Forgive my ignorance im only just learning about sumps
Im envisioning the water in the tank droping a few inches until it gets lower than the overflow , the oeverflow loses siphon at that point only water from the sump is being drained. How would you do really large wc's ?
