It has come to our attention that there are Companies selling recycled PVC liners. PVC liners cannot be recycled, these so called recycled PVC, is in fact old Advertising banners that are collected and joined for use as liners. Banner material is not manufactured to last or be used as liners. They have a short lifespan, and can leach chemicals into the water.
