Ok, I have 2 jandy valves on this pool. One is on the line for the main pump going into the filter. The other is in front of the salt cell. The one in front of the salt cell is currently turned counter- clockwise. This is allowing water to flow through the salt cell but i have NO returns!. If i turn the valve all the way clockwise, I have returns but then you can tell theres no water flowing through the ssalt cell. Pool turnd green over the weekend. I have both skimmers and main drain valves wide open. Any Help??
