It was Chorlton however who started brightly in the 2nd half and pulled a goal back, albeit somewhat fortunately directly from a cross.
After South grabbed a third, Chorlton pulled one back a minute later to set up a nervy last 20 - but South held on to get the all-important three points.
South Manchester joint-manager Neil Collins said: "The boys showed great strength to hold out and get back to winning ways after a tough beating last week.
"Credit to the boys, they were a shining light for others to follow and we look forward to our final game next week before the Chanukah break."
