I have just taken posession of a Niagara 31 (my first boat
). I found that the icebox drain is hooked to a footpump (tap water) by a two-way valve. To drain the ice box I flip the valve from the water tank to the icebox drain and use the drinking water foot pump to pump the effluent through the tap into the sink to drain away. To me this seems very unsanitary. I was thinking of connecting the icebox drain to one of the cockpit drains close to the hull to allow passive drainage. Do I need a shut off valve in this line or is there a better way in general to correct this problem?
