My 'Anderson" valve was leaking recently. It was at the threaded joint behind the valve where the selector valve is tied across to the water heater bypass valve. I had to take off all of the water tubes at the rear, and then take the valve out from the back. I remade the joint using PTFE tape, and now all is fine. It was awkward working behind the valve, but I marked every line with a code so that I wouldn't get them crossed when I reconnected them. If you do this, take care to ensure that the rubber washers inside the female portion of the tubing connectors don't fall out when the tubes are taken off.
