By the pictures it was impossible to see the design. What you have on the table in the first pic of it is NOT what is pictured in the diagram in the link you posted.

Making the changes you drew will fix it.

I agree that the pictures couldn't tell you much, but that is as good as I could do. I did not draw any changes, and the picture of the parts is just like the link. I edited my original to try and make it more clear.

Also, it completely makes sense that I need the T as high as possible. The only reason that it is as low as it is was because of previous advice a couple months ago on this forum. I was asking where to put the T, and I was told to put it where it will not quite fill the sump if the power should shut off. That is why it is where it is. So essentially my whole overflow is garbage now if I want to put the T in the correct place.

On a good note, I haven't had to adjust the ball valve for almost three hours now, so until I can afford to re-do the overflow, it looks like it will be staying like this if it can survive through the night.

Thank you dmopar :headbang2
 
you should just buy a commercial overflow box it will solve your problems and you never put a ball valve on the overlow. the water flowing thru your tank in a wet dry system is regulated by your return pump. all your doing with the ball valve is trying to match the output from your return pump and risk overflowing your tank.
 
The T only goes high on the overflow if you're using the type that has the pipe opening down in the tank. If you're using the one where the water overflows into the pipe, it needs to be toward the bottom.

Why don't you look at the sticky post on DIY overflows instead of trying to reinvent something that already is tried and tested?
