I have a 6-year-old vinyl liner pool. For some reason I am getting sand and gravel in between the liner and the pool walls (you can readily feel it with your hand). Seems to get worse every year. The only thing I can think of is the winter freeze/thaw (I'm in Ontario) has separated the aluminum coping the top of the pool wall and the A-gravel under the concrete deck is getting washed between the two. However everything looks fine from the outside. Anyone ever heard of this?
Thanks,
Sean
