Sump baffle design

[rainsong]

I purchased a baffle kit for my 40b sump and am working on locations for the baffles.

I understand that the return pump section needs to be large enough to hold water to cover the return pump as well as all the water that drains when the pump is turned off — from the overflow (above the standpipe), the plumbing and any reverse syphoned water until the syphon break.

However, when the pump is turned off, is it normal for the water levels to be higher than the baffles? Or is this something to avoid.

That is normal

Completely normal.

When I turn off my return, and empty my overflow, my sump is nearly full, and well over the baffles. As long as during a power outage(drain down) your sump can handle the load, it's fine if the water level is over the baffles.
