I am not sure about the fresh water tank drain on my 2007 Seneca 34 SS.
In the compartment where the dump valves and water fill stuff is, on the rear wall near the door opening are three "Low Point Drains" clearly labeled.
In the corner is another similar looking line with a valve that is not labeled.
Aparrently it is a drain too I dont know what it is.
I do not see anything that labeled freesh water tank drain.
Any help would be appreciated especially a picture with a big fat red arrow,
OK just a picture would be really good.

Yes I did try a search.
