I am losing <1" per day,maybe 3/4max, but definitely more than evaporation. I will try the bucket test to get an accurate measure. I will plug the skimmer and drain and see how that affects the loss.

Have you ever heard of leaking through the gunite wall (without the notice of an actual crack visible)?

Also, do you know how small the leak can be to cause this water loss? (should I be looking for something very minor)? When i hear losing 3 -4 inches plus / day, that is much more than our pool is losing.

But, up till last week, the level did not change at all (except minor evaporation)... But over the last week or so, i need to add 1"+ / every other day.

Thanks,

John
