Hi y'all put in a used 30 foot round pool when putting in j hook liner seams small but got about 6 in of water in it and needs to stretch to contact the wall ? Is if I can push it out with my feet to the cove and wall will it have no problem stretching it self to that? Seems like is got like 7 in to stretch to reach the wall but like I said I can push it out with my leg to make it toch the wall just wondering if this is ok?
