I guess it's Hans... you bring up a good point about the expansion of tubing and hoses, We tighten hose clamps "cold" which when they get hot the constant tension clamps squeeze into the hose. I've never thought of that until your post... Thanks,

I just wished that I was aware of the heat shrink clamps when I completed my water system. The first opportunity that I need to drain the radiators, I'll look into the heat shrink clamps. Typically how much can they shrink, 10%, 20%?

Thanks,
