Q: Reading installation instructions and then reading through the Q&A responses from Hayward here differ. So is the pool liner opening cut and then the wall saver gasket goes over the inside wall + liner, or is the gasket installed into the opening and liner is sandwiched between the faceplate and gasket? So faceplate, gasket, liner or faceplate, liner, gasket?
