Those of you with AGP and solid ice freezing in the winter:
This is the first year we will have hard plumbed water lines going into the winter. We have hard freezes and the AGP becomes on solid block of ice. In the past, we have disconnected the hoses on the skimmer and inlet and left them open in case overflow water needed to drain. We do not remove the skimmer from the wall but do make sure it is covered by the winter cover.
How do you handle the hard plumbing lines when the water freezes solid? Do you disconnect the lines at the wall skimmer, and inlet, and leave them open/detached during the winter? We will be using a mesh cover this fall, so water might get in it. My husband and I are not in agreement but we want to make sure water getting in the skimmer will not freeze, expand, and crack the skimmer.
What have you all done?
