No. The salt is not causing the edema but it might be contributing to the drinking. Try taking the block away and just putting 2 oz of salt in the bottom of her feed tub every day. If that doesn't resolve the drinking and urination issue it might be a sign of uncontrolled PPID. Need to make sure the ACTH is controlled. The usual procedure is to get them up to 1 mg/day then retest in 3 weeks.
