We had two hurricanes come through in the past two years (Irene and Sandy). Both Hurricanes brought a lot of rain. We bought this home in 2011 and have since noticed a floating liner issue. I have had to drain the water out from behind the liner at least 10 times since we move here due to heavy rains.
Originally the pool company we hired to come look at the job said they wanted to do a well to help alleviate the water issue. However once they broke ground on several different spots they concluded that tapping the wall in a few spots would solve the issue. They thought we may have an underground swell, but when they dug the soil was not as bad as they thought. We live in Delaware, so we have a lot of clay.
His idea is to fill in around the colar with gravel and a preferated pipe. Have the perferated pipe poke through a few spots under the liner so that water can escape rather than be trapped. He also wants to put preferated pipe along the inside corners of the wall, but he said he may not have to do that. He thinks the wall taps will be enough. Due to the elevation on the right side of the pool we may still need to do a well over there, but the left side seems to be ok with a gravity drain due to the pitch.
I just wanted to throw this out on the forum to receive some feedback. I want to make sure we fix this right the first time. We are having them install the drain/well now so we an monitor it over the winter and spring before installing a new liner.
