We talked to PB about the rough crete on the polymer walls under the liner. One place, about a 3 ft section is extremely bumpy. It is about 2 to 21/2 ft below skimmer.The pool will have to be drain about 3 to 3 1/2 ft for the PB to get to the very rough poolcrete or concrete (could be, since the PB put some in the bottom, before the poolcrete was installed) that was spashed or spilled on the walls. I hestitate to let the PB remove the liner pass the returns, light, and polaris port. I am afraid that the liner will not fit correctly back in place, and will leak around these areas. Yet, the crete is very rough, and I don't like it, either. Any input? Thanks to all of you, who take the time to share your knowledge and experiences.
