Bitton followed up their midweek victory over Larkhall Athletic by winning 4-0 at Hallen in the Toolstation League Premier Division on Saturday.
Luke Bryan and Tom Morgan both struck either side of an Aysa Corrick double as Bitton maintained their hold on sixth spot.
Larkhall, who hadn't lost in the league until Thursday, looked set for a second defeat in three days as they trailed 2-1 at third-placed Gillingham Town going into injury-time.
However, Nat Auckland struck to earn a deserved point for the ten-mark Larks, who had earlier taken the lead just after half-time through Steve Bridges.
Gillingham levelled within ten minutes and then took the lead from the penalty spot after Steve Casey was adjudged to have pulled down a home player.
Ross Lye received a second yellow moments later but the visitors dug deep to get some reward, although they dropped to second in the table on goal difference following Bristol Manor Farm's win at Cadbury Heath.
Odd Down, who had also drawn 2-2 at Gillingham last week, suffered a 1-0 home defeat to Sherborne Town.
