I am remodeling my kitchen and bathroom and I will be replacing the bathtub with a stall shower and moving the kitchen sink to a corner position.
The refrence books I am using refer to a vent for each appliance. My problem is as follows: the existing drain does not vent to the roof (or any place else). Does anyone know of an alternative to running a pipe from the basement though two floors of living space then out the roof. Thanks.
