I have an AGP and live in a cold climate. Last week we had a period of warm weather and noticed what I thought was the water level going down. Yesterday I looked again and with it colder again there is probably about 2 feet of frozen water in the pool now.
In the fall it was my first closing but I followed TFP method to a T and followed the previous homeowners instructions on blowing out the main drain. The only thing I can think of that happened was water got into the drain line, froze and bursted somewhere under the pool. I see no water or sign of a leak anywhere near the exposed drain line or anywhere around the pool itself.
Any advice as to what I can do now or in the spring. If it's completely drained by spring is my liner ruined, etc.
