The Studor AIV needs to be accessible, so if you do not wish to install an access panel then the vent pipe has to be extended into the attic for access. Because of the way an AIV works, they should not be installed on every pipe in a house. At least one pipe, preferably the one farthest from the sewer's exit from the house to the street, should penetrate the roof as a conventional vent. Not doing this would create a situation where, under the right conditions, none of the drains in the house would work. Having just one vent out the roof, however, will not completely prevent some drains from draining properly under certain conditions, depending on the exact piping layout of the residence.
: I'm building a small house and the kitchen and bath share a wall. The lav sink and kitchen sink are on that wall, but the toilet is not. I was looking on the Studor website and their diagrams still show a pipe to roof even with Studor valves??? Will I still need a pipe thru the roof using Studors?
