It got down to 26 last nite. When I went to feed and change my water I could not get any water through the hose. I have two hoses hooked together and noticed water spraying at the connection between the two. My green hose was froze solid but once I unhooked it from yellow hose before it I had all the pressure in the world. Is this a freak thing? Difference in materials making yellow hose insulate better? Does the yellow hose just soak in the sun better? I want to get to the bottom of this because if this is not a freak thing and yellow hoses are less likely to freeze or thaw quicker I will switch. Any ideas?
