out of reserve and moved to Bremerton, Washington, where she began a nine-month overhaul preparatory to her return to active service. While the destroyer was at Puget Sound, the Navy adopted the alphanumeric system of hull designations, and Waters became DD-115 on or about 17 July 1920. She completed her reconditioning on 30 November and returned to San Diego at the end of the first week in December. During the first few months of 1921, she operated as a unit of Division X, a special organizational unit, to which and Dent were also attached, pending the reconstitution of Division 14 in its entirety. In January and February, she made a cruise to Central and South America. She stopped in the Panama Canal Zone on her way south and visited Valparaíso and Mejillones Bay in Chile during the first two weeks of February and then returned to Panama for nine days of battle practice with the Fleet.

Waters remained there until 21 June when she got underway north and, following brief stops at San Pedro and Mare Island, entered Bremerton, Washington, on 27 June to prepare at the Puget Sound Navy Yard for duty in the Far East. Almost a month later, she returned south to San Francisco, whence she sailed for the Far East on 21 July.

The destroyer remained in the vicinity of Luzon through most of her tour of duty in the Orient. She visited Olongapo and Manila frequently and conducted combat training and torpedo exercises off the northwestern shores of the island in Lingayen Gulf.
