I completely agree, although I just installed it. Hope water softens some here in next month,as we are ready to put our newest boat to work. How did you vent head? Mine(natures head) vents thru the former pump out port. Another post on another forum used a mushroom style with screw down lid for water intrusion control. Thinking about doing the same when next I am at the boat(250 miles away). Any ideas are welcome, thanks, Bob
