So I've finally got around to landscaping around my 27' pool that was installed in July of this year. Throughout the summer I was adding a great deal of water. Expected to find a leak over the winter but the water level has stayed perfect since covering for the winter. I didn't want to put anything against the pool if the liner was gonna have to be replaced but now I know for sure it's safe to move forward. 1-2 times a year we see standing water in our backyard. It has become a stream during continuous heavy rain. We explained this to the installer and he suggested a retaining wall and a French drain to ensure no water runs under or against the pool. My question is do I install this French drain setup right against the base of the pool? Or should I place it in a trench a little bit away from the pool? Thanks in advance!
