I think we need a new liner as the water level went down drastically over the winter. We cannot get a new one installed for 5-6 weeks. Is it okay to let the pool as is. It has no water in shallow end and water starts about 6 inches from where it slopes down into deep end. I thought you are supposed to keep water in them. But if it's okay as is then I won't bother filling only to have to drain again in a month.
