I don't know what valve he would have removed. Post a picture of where he removed it form.
If the softener doesn't use a float to shut off the brine refill water flow, then you program the control valve for the salt dose lbs. Depending on the model of control valve you have, you would set the number of minutes the Refill water runs for.
Post a couple pictures of the control valve.
Do you get a good flow of water into the salt tank during Refill?
