I was one of the people who mentioned that the combo fittings looked like sanitary tees. I'm very pleased that you narrated through this configuration and identified the fittings by name on this video.
I did have other constructed criticisms of your last plumbing video, but I see nothing wrong with what you've done here.
Although I don't believe it's necessary by code, I understand that most plumbers use a 4" to 3" reducing 90⁰ for the toilet. As I understand it, it's the only place the code allows for a reduction in drain size, in the direction of flow.
I personally don't understand the necessity for a 4" pipe at the toilet, especially given the 1.6 gal flush volume of the new toilets. But, I use them because I figure there might be a reason that I'm not aware of. No plumbers ever told me why they don't bite their nails either, but that sounds like generally good advice, too.
