I just threw that out as a suggested safe number from me. Your water system is rated by Heartland at aound, I think, 50psi. I do not know the exact number.Thanks for the info! Is 15PSI the max I should use for the hole system?
I don't think that water in the icemaker tray will hurt. It freezes when you make ice all the time. The solenoid valve and the supply line to the icemaker is what needs to be clear. I've just followed Dometic's instructions and have had no problems. Definitely don't anti-freeze in there, you'd need a lot of rum in the drinks to compensate for the bad tasting cubes!After I turned off the water supply to the icemaker, blew water out of the supply tube and blew water out of the solenoid valve, there was still water in the icemaker tray itself which would freeze. So I had to unscrew the icemaker from the backwall, remove it and empty the water. Blowing air into the line will not get rid of this water. A logical step to easily miss. Also I wouldnt blow the pink stuff into the icemaker. Might not get the taste out next time it is used.
Just behind the removable panel in the basement. On my 2011 Rushmore there is a shutoff valve near the back of the docking center. I assume the Grand Canyon will be in about the same location. I blew out all my line and ice maker. Will shutoff the frig line and use anti-freeze to be sure. Cost of about $30. Cheap to make sure I don't freeze up in upstate NY.
What's the $30 for?
Pink stuff.
