[C320-list] Hot water bypass

Tue May 26 13:07:58 PDT 2015

I would follow Jeff's recommendations. Or just replace the hot water tank and do it right. The time you spend by-passing everything, just add an hour and the tank could  be replaced.

Bill, others
I don't see any evidence of antifreeze leaking into the bilge at this time.

However, if I understand what others have written, some feel it is dangerous to bypass just the fresh water, leaving the engine side connected.  Actually, if I had to bypass both sides of the system, I would probably not do it at all right now and get by using bottled water for a while.  I think that to bypass the engine side means moving or removing the entire water heater in order to get to the back of the unit.  That kind of defeats my goal of putting the job off for a while (my wife will tell you I'm good at that).

Not sure what to do with all this................

Thanks to everyone for the input.
