We opened pool and was using until last week. We needed to replace skimmer faceplate. When we went to, realized we needed a gasket. So pool was off for one week waiting for part. Water was drained a couple inches below skimmer. When we try to get it up and running again it wouldn’t take prime on filter. It will backwash and rinse. It will not send water back to return lines to jets on filter or recirculate.
