What causes a pool liner to float?
A vinyl pool liner can "float" if it is not installed properly or if water has come between the liner and the pool wall. Often, this will begin with large air pockets or bubbles on the liner wall. If these are not corrected properly, the liner can detach from the walls and padding and float in the pool. The original source of this problem is usually a hole or a leak in the liner. The best option when this happens is to drain the pool and repair or replace the liner as quickly as possible to avoid further damage to the liner or collapse of the pool walls.
