How necessary are ice compensators in in-ground, painted or tiled concrete pools? (some painted with a tile border, some tiled throughout).
Winters here have an average of night-time low of -4C for three months, with occasional night-time drops to -10C and the occasional cold snap of -20C for a handful of days once or twice a year. Record lows of -36C have happened.
Most of the pools I've seen do not use them. All are drained a bit below the tile, except for the ones that are completely tiled of course. Do ice compensators protect the paint? I thought ice damage to paint only happened when the ice sheet moved up or down, not from pressure.
