Hello,
I've gathered a lot of info from this site, but this is the first time posting on here. I couldn't find a direct answer to my situation so I wanted to get some opinions.
I am having a sewer line replaced in my basement, that is under the concrete floor. While it is being replaced I figured I would replace all the existing pipes from the utility sink and upstairs sink leading to it with ABS. I also wanted to add a standpipe for the washing machine instead of just having it drain into the sink as it currently does.
I watched this video from this old house on youtube that seems to be very similar to my scenario (although I already have the sink). But I had a few questions.
THIS VIDEO IS INCORRECT. NONE OF THIS WILL EVER PASS A PLUMBING INSPECTION
1. They use a WYE fitting to add the sink and standpipe, it would seem like I could just put in a sanitary tee above the cleanout on the vent pipe to the right and it would be easier and still work correctly. The vent goes up into the first story of the house and tee's into the kitchen sink drain up there. So believe my venting situation is slightly different then in the video since there is no drain coming in from above it.
2. The pipe being replaced in the ground is 3", and the current piping above is 1.5" is there any benefit for me to enlarge all the piping above to 2" (of course the vent and drain coming from the first floor would be attached with reducing couplings and remain 1.5")? I just assumed the larger pipe would be less likely to have blockages from the utility sink and washing machine.
Thanks for any insight.
