95 Crown Royale /Signature/ Dynasty.Early winterize this year 21f tonight Chicago area.
I have the multi manifold all valves are open no pipes disconnected only one hot blank. I tried to make ice/antifreeze cubes for first time I've owned it. It was final water line to winterize. No liquid went into tray ,so I removed the 1/2" feed line.it was dry as a bone.Pump full at full pressure. A bit of old pink in 1/4" line. I have been all around all adjacent cabinets .Removed some utility type panels under range in cabinet.Filer under sink only went to Insta hot and it's cold side of its faucet.
I guess it could plug up with lime or sediment if never used. If PO wanted to trap antifreeze in line could of just closed the manifold valve.I can only read half the manifold valve labels I guess next step to find the valve disconnect line and blow back with regulated air. Unless someone has an idea.

I think you have the right idea. Turn the pump off and plug the inlets. Then open the cold valve in the kitchen sink and remove the screen before blowing it out. That should keep the crud out of the rest of the system. Let fresh water run through the ice maker line and the kitchen faucet before reinstalling the screen and ice maker. Are you sure there is no shut off in the line? If no luck pour some vinegar into the line and let it sit overnight. Good luck!

Thanks but the filter was only for Insta hot and filtered cold faucet. I made a hose to bypass the filter. Insta hot was froze at one time, its old school 3 piece brass tank . I think I can solder it back together with pipe solder.I did radiator repair as young man. Not the end of world if I can't make it work again.

SOLVED
Blew the line back a unit had line removed from manifold. I could hear air blowing out a filter . The filter quick connect was closing off the line from pump. The valve was still open. After pulling mini freezer icemaker I could see behind it to under cabinet secret false floor. No finger hole. Valve and filter were both there as I suspected , just didn't know where.
There was a huge mouse nest to clean up. Glad the didn't chew up all that gear under there.
