The pan outlet is about 350mm distance to the soil stack on a 90 degree bend to the left just discovered that the original new toilet i chose the pan outlet is lower than the soil outlet. It s probably best to say check the height of the spigot of the pan you intend to fit as different products do vary even if they are from the same manufacturer. Water supply lines are usually just a couple of inches higher between 20 and 22 inches from the floor and installed one to each side of the drain line.
