Water drains

[i4110peter]

I know about the water drain under the back. Found another drain when filling the tank that is just open! Is this an over flow drain or should it have a shut off. This is a 2018 BH3160EL. Thanks in advance.

You'll have 1 or 2 overflow drains coming from the fresh tank. There's usually 1 on each side, terminating outside the frame in a 90 degree PEX fitting.
