In a previous thread (https://terrylove.com/forums/showthread.php?37280-Help-With-Adding-A-Vent) Terry said that “Whenever you go from vertical to horizontal, it needs to be a wye fitting. (combo or wye with 45)”
In checking the plumbing under my house I see that all the vertical drops make a 90 before entering the main drain line horizontally. For these horizontal connections they have used a mixture of santees (in the 1978 part) and combos (in the 1991 addition). Does it make any difference under UPC if a connection in the horizontal plane is made with a santee or a combo? What are the rules for the use of each type? Just curious.
