So I didn't get to fill my rink this year until Thursday night / Friday morning due to 6 day work weeks and hockey games. I expanded it to 48 feet this year and moved it to where a swing set was. That gave me only a 5" pitch which is fantastic. Night was in the low teens but due to the slow flow of my outdoor hose it didn't get filled until close to 1 AM. Went to sleep with it already glazing over. There was a 40% chance of snow and sure enough about 6 AM there was a coating on it and ended up with about a 1/2" by 9 AM when it ended. Snow caused it to start have holes and wet spots. When I was finally able to get the snow off I was left with a lower level and about an inch of ice and no water underneath the ice. I know the weight caused problems with it freezing by insulating it and pushing down on it. Am I looking at a hole in my liner?? Or did the weight of the snow force the water out and how? If I had a hole in the liner it had to be small enough that the fill was faster than the leak?? If I try and fill again am I looking at it leaking out again if I don't see a visible leak which I didn't or was it the snow?
