[C320-list] Water supply line size

[Jeff Smith]

Mark,

Thanks. After cutting the hose at the fitting, I think I did not have a the hose fully inserted in the new whale fitting which is why it was leaking. I may need to run new hose. If so, your method sounds more reasonable than what I was going to attempt (duct taping the new tube to the old, assuming the obvious risk of the two separating while being pulled). I should be able to run the new tubing over the electrician’s fish tape. 

My current dilemma is trying to decide if it is worth it to just convert to shark bites and the appropriate size pex tubing (1/2”) as I need to replace hoses and fittings. I could also use crimp rings but there is probably a safety reason that I am not considering not to switch to crimp rings plus that might be hard to execute in certain spots. Availability of material is the main reason to switch. I know I have a leak either in my forward water tank or line. That has been dumping all of my forward tank water into the grid below my bilge. 

I will let everyone know if I decide to run new lines, etc.

(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.

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.

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.
