I am preparing to install an 84" vanity with dual sinks, and then I find out the sink drains are 34" apart. That would require individual p-traps. But when I opened the wall, the existing single sink vanity drains into a 1.5" vertical pipe. This is a 1928 home, with various remodels over the years, and there is no way to get a 2" pipe to the top floor master bathroom without tearing out floors and ceilings. When I proposed to the inspector the
method I found on these forums from Terry Love, they said it violates the code.
I don't get it. If the sinks are 30" apart, they can share a p-trap and go out the single 1.5" drain. But at 34", with a much more robust setup such as this, they say 'no'. Not only is the flow out a vanity sink small, but as anyone who has shared a bathroom with dual vanity knows, it would be rare for both sinks to be draining much water at the same time.
I don't know what I can do.
