I have a 100 year old house with an 'S' trap in a 1st floor kitchen sink. The current configuration is the 'S' trap in a 1 1/2" line then a 3' drop to a 2" horizontal cast iron pipe running about 8' to the main stack.
I'd like to know if there are any alternatives to installing a standard wall vent and avoiding a procedure that would require extensive tear out of walls and ceiling on both the 1st and 2nd floors.
Would an air vent like those used on kitchen islands meet national code?
Can it be wet vented in the basement from just where it breaks through the basement ceiling? This would involve a 'T' into the existing drain then running a horizontal line about 7' to 'T' into the vent coming up from the basement laundry sink?
Any other suggestions? Thanks!!
