* Per ASTM standards, 6" Schedule 40 PVC pipe can vary significantly in the inside diameter (up to .090") compared to the better precision of a good casting (.010"). Additionally, pipe from various suppliers can vary significantly within that range. Generally, most suppliers try to make the pipe wall as thin as the specifications will allow in order to save material.
