I replaced all the tile at the waterline of my pool over the summer because every time we have a really hard freeze multiple pieces of the tile are cracked by the ice that forms. Could I drain the pool enough to get the water level below the tile (and subsequently below the two skimmers) and keep the pool circulating using only the main drain at the bottom of the pool? And if I did this, would I run the risk of the plastic tubing that runs from both skimmers to the pump room bursting? If so, is there something I could do to prevent that occurrence? I assume that would be a catastrophic event.
