I'm new to the above ground pool thing. I've watched many videos on how to install the hayward skimmer but they've all been on round pools. I'm not sure where the skimmer should be placed on the pool and how high the water should be as I place it. On my pool the top bars bow inward until the pool full. I'm nervous that if the water level is not where it's supposed to be and I install the skimmer, once I fill the pool up it will stretch and leak....please help!
