We done it on a big rig one time we used a rod about 1 1/4 and made it where we could drop the hdpe down the hole and winch that monster up. It was around 17 ft . But we dug quick in sand withouta lotta jug mud the sandy layers dropped in at times so the 17ft of metal dropped in through it like a missal .
