Division Four East saw Gwernyfed surge eight points clear at the top of the table as their forwards laid the foundations for their 24-13 triumph at home to rock bottom Talywain.
In Division Three South East, Tylorstown made the most of appalling conditions to record a creditable 24-12 bonus point win at Brecon. No.8 and captain Steve Hogan led the way with a try while Mark Davies, Kieran Morris and Adam Thomas followed suit.
In Division Two East, Penallta's Matthew Angel was his side's saviour as his try won a gruelling contest against Rhydyfelin 5-0. The prop forward crashed over in the mud shortly after half time to decide a fierce contest in which a player from each side saw red for fighting.
Elsewhere, Mountain Ash and Ynysybwl each claimed a bonus point win against Pill Harriers and Tredegar respectively.
