Well,haven't been on here in a while.My liner ripp'd over the winter.So I drain'd the water in the spring&didn't do anything with it.Well,thinking about replacing the liner.Concern'd with the hard rain's we have had.Noticed the cove of sand is down.I'm thinking of just sweeping up the floor&going for it.I had such a bad experience the last liner replacement I did.Had alot of liner lap over on 2 side's of the wall.The bottom has a few low spot's in it .Should I just start from scratch with a level&some wood&rework the bottom.Any suggestion's.Also had a bead'd receiver.How hard is it to go with a pull over liner??Took a couple pictures.Thank's for any info
