No. I figured it’s a moot point since I bought it second hand

According to Red Sea thisnshouldnt be an issue. Something about equilibrium or something. I’m going to put some spare heaters in the tank and turn it off for 8 hours one weekend to see if I’m crazy or not.
As long as your drains and return aren't leaking, the only water that should go into the sump is water that is above the top of shortest of the three pipes. Once the return is turned off, the overflow and DT will equalize at that level. Now, if you happen to get aother leaky seal and the power goes off, then you're in trouble.
