Lee,
On 3/5 2006 you posted that you put a vacuum valve in the heater hose line to produce a positive shut off of water so the Max air system would blow only cold air in your Dolphin motorhome. A couple of questions: 1.) Is the ID of the heater hose 5/8 or 3/4? 2.) Where did you pick up the vacuum line to actual the valve?
I have a 2004 Dolphin lx6342, bought in Jan, and no manuals that actually show schematics or real technical detail.
Thanks,
Brian K.
