Hello,
I have what appears to be an equalizer port and I am just trying to figure out more about its purpose and if it should be open or closed during normal use (we have always kept it closed). We do not have a main drain if that makes a difference.
From my googling, it appears it helps the skimmer not suck in air if the water level drops too low, is that correct?

Thanks
