I've been thinking about adding a bathroom to my unfinished basement. After reading the article in the latest Finehomebuilding I'm even more eager.
I have an old house with mostly cast iron plumbing with only one 4 inch vent. I'm going to have to install an ejection pump because my sewer line leaves the house above the basement floor level. I have no common wall to run a vent. Would it be a bad idea to install a boca vent for the basement system?
I'll have a toilet, shower, vanity, washing machine and most likely another sink for this system. If a boca vent will work, what size should l use?
