Air Under Liner

Hello,

Today I noticed the dolphin was getting stuck in a certain spot. I looked closely and noticed that there was a large air bubble under the liner.

What causes this, and what should I do to fix it?

Thanks...

This would most likely be a water bubble under the liner. It is caused by the ground water level outside the pool getting higher than the water level in the pool, causing water to get behind the liner. If you raise your water level to its normal position this should push the water behind the liner back into the ground. You may have wrinkles after this happens. You could either re-lower the water level after a period of no rain and use a plunger to try and pull the wrinkle to the wall, or you could drain the water below the wrinkle and try to pull the wrinkle out.
