Source of water leak at unsoldered joint at male adapter connection to spout at three handled tub/shower valve. Remove Tub spout, tubing and fittings. Furnish and install all new material. Noted severe resistance on operation of recently new diverter stem assembly installation. Remove trim and back off packing nut. Apply silicone lubricant and reinstall packing nut with enough resistance to prevent water leaking through this packing. Continuation of existing warranties on both repairs.
