An improved sprinkler housing particularly adapted for mounting on flat terrain which permits the installer to easily adjust the level of the housing in order to suit the local terrain without changing the nipple at its bottom end. The sprinkler housing is adjusted by means of turning a rod which is pivotably coupled parallel to the sprinkler housing so that an eccentric lock connected to the end of the rod and engaged to the coupling or nipple, locks the coupling after the proper height adjustment has been completed.
