In 1922–23, the club found itself with sufficient players to establish an “A” (2nd) XV. The same season, after having played matches at Singleton Park, the recreation ground and St. Helens, the club obtained the lease on a pitch near The Bible College, Derwen Fawr, where they continued to play until the outbreak of World War II, although some matches were still played at St. Helens. In 1928, proposed by Pontardawe RFC and seconded by Pontarddulais RFC, the club applied for membership of the Welsh Rugby Union and at a meeting of the W.R.U. on 13 September 1928 this was granted.
