We have been getting tons of rain here in NY,and now have two nice size pockets of water behind my liner.Just wondering how easy it will be to remove some of the liner from the coping to suck the water out.Are their any tricks of the trade to get the liner out easily (and back in ).Can i safely untuck a small section of liner or i run the risk of losing it?the liner is tight in the deep end where the water is , but loose in the shallow end where the other bubble is.Also is it safe to run my tigershark robot with the liner floating like this? Thanks in advance
