Brand new pool in box but based on instructions I’m afraid I’m missing some parts or have duplicates. I have two strainer grid pieces but no rubber washer to place against the inside of the pool next to these strainer grid pieces. Also both 2 piece strainer things look the same so am I missing an intake or an out take piece? Also, am I missing the rubber washers for inside the pool?The pool came with the hoses and filter pump. Just seems like I’m missing washers and can’t find any current videos or explanations for a 2020 Intex easyset pool this size. Thanks for ANY help!
