[C320-list] Water supply line size

[mark]

Jeff,

It sounds like the aft tank and supply line you have are in the same place as my 1995 model.  (Water tank under berth in aft cabin, and water line runs under the engine pan and galley floor to the pump under the sink in the galley.)  If I were trying to replace that water line (and assuming the line is mostly intact) I would try running an electrician's fish tape through the old water line, until it came out underneath the sink.  If the fish tape was too big to slide through the old water line, you might be able to use 1/8 inch galvanized wire rope from Home Depot.  Whatever you use just needs to be narrow enough and stiff enough that you can push it through the old water line.  

Once you get your fish tape or wire rope to the galley, pull the old line out from under the sink, and feed the new line in from there as well.  You might be able to just slide the new water line over the fish tape or wire rope as a guide, to get it to follow the same path as the old one.  Or you could use the tape or wire rope to pull the new water line back through to the aft water tank.  But if you do that, be sure that your connection between the water line and the fish tape or the wire rope is solid, because if they separate you've lost the ability to track back through the same path.

If you do replace the line, let us know what worked, as I may have to actually do this myself one day, and actual experience beats the heck out of guesses about what I would do if. . . .

Jon,

Thanks. That is the information I need. I did have a new 15mm whale fitting but it is leaking as well. I would just replace the hose but it disappears under the engine pan. It sounds like I can’t use 1/2”. I guess I will try cutting a small portion of the hose and getting a clean edge for the new whale fitting.

Thanks,
Jeff
