There was a quick response by Tom Munton, who finished neatly to level.
Coddington then took control as James Lloyd, Josh King and Josh Johnson gave them a 4-1 advantage.
Flowserve hit back in the second-half through Callum Barnes and Daryl Price before Ashley Reed levelled four minutes from time.
However, Coddington grabbed a dramatic 5-4 victory through King, who took advantage of a defensive mistake after Lloyd’s initial effort was cleared off the line, to go fourth.
Leaders Newark Town continued their procession towards the title with a 7-0 home win against East Bridgford Rangers.
