>>I need to install a basement sink located 4 feet from a main soil
>> basement stack. The 3" PVC main soil stack drains 3 fixtures (toilet,
>> kitchen sink, bath sink) on the above first floor. The following vent
>> configurations for the basement sink would use 1.5" PVC:
>>
>> 1. Install a (circuit) revent to stack.
>>
>> 2. Install a wet vent directly to the stack.
>>
>> 3. Install a (long) branch vent. The branch vent would have about 50
>> feet of horizontal 1.5" PVC with five 90-degree turns installed on the
>> basement ceiling. This would connect to a branch vent (1.5") PVC of
>> 42 feet vertical length that connects to the main vent in the attic
>> and through the roof. Due to the length of this configuration, this
>> vent would not have a slope, but should be dry.
>>
>> Which one of these three is best/acceptable? Thanks.
