@ GW, I know you know this but if it is a valve there will be water in the valve box. If not, good luck it is in your line somewhere. I think I remember you saying there were no wet spots.....hmmm.

The end cap adaptor and the liquid to air heat exchanger for my test sled both arrived yesterday and I will be installing the heat exchanger today.
