With the elements in their favour, Pencoed dominated the opening quarter territorially but had to wait until the 26th minute before opening the scoring at Cwmavon.
Full back Ryan Russell broke down the right evading a couple of home defenders to feed wing Jamie Dyer, who did extremely well to squeeze in at the corner flag.
The Pencoed front row of James Tredray, debutant youth hooker Zac Taylor, and Brandon Nelson were in the ascendancy and several dominant scrums approaching the interval kept Pencoed on top, however the score remained 0-5 at the break.
Pencoed then got an early foothold in the home 22 on the resumption of play and a couple of effective carries from prop Nelson set up the second try, supporting second row Ricky Somers unselfishly providing the try scoring pass to David Young who ran around behind the posts, Jamie Pensom adding the extras.
Cwmavon then went on to enjoy their best period of the match with the changes to their pack giving them impetus at the set piece.
Going into the final 10 minutes, the home side were camped on the Pencoed try line but a superb committed defensive effort from Pencoed denied Cwmavon a score.
Keeping their line intact during this onslaught was to ultimately win them the match, with one hit from centre Lloyd Bargery deep in his own 22 typifying the Pencoed resolve.
This much-changed youthful Pencoed squad deserved this hard-fought win and will look to consolidate their top half of the table position over their remaining games.
On saturday Pencoed host Nantymoel at the Recreation Ground in Division 2 West Central, 2,30pm ko.
