aboveground pools with decks makes it very hard to change liners unless your pool has a hung liner. over the wall liner requires removal of top rails and caps. impossible with above the rail decking and extremely difficult/impossible with below rail unless a large enough gap is left to pull liner over wall, install coping and replace rails. having done hundreds of aboveground pools and half as many liner changes, I either turned the job down when there's a deck, removed enough decking to do my job, or if there is enough room to get to liner changed, *****ed and moaned the entire time I'm crawling under the deck, getting buzzed by wasps, banging my head on deck supports and swearing that was my last liner change with a deck. I don't do those anymore. above ground pools really need decks but plan ahead for liner changes. if your pool uses a hung liner, disregard all this and go for it. BTW, a hung liner has a bead on the edge that rides in a track around inside top edge of wall so top rail doesn't need to be removed for liner change
