Catalina 22 Paradise, MO
The previous owner of the Catalina C25 that I just purchased removed the sink in the galley and the ice chest drain is leaking at a valve just under the cook top. Anyone know what this valve is for and why it might have some connection to the ice chest.

The icebox drain was teed to the sink drain. The valve was added stop seawater entering the icebox while heeling.
