Hi, I am in the process of adding a basement utility sink and I would greatly appreciate if someone could sanity check my drain plans. There is an existing upper level kitchen sink on a 2" vented drain that drops down into the basement with about 20ft of horizontal which taps into the main 3" which runs out to the septic. The no trap/no vent utility sink pump will discharge into a 1-1/4" 6' vertical and about 10' horizontal and then tee into the 2" downstream of the kitchen sink. My logic is that this is downstream of the vent so there is no risk of clearing the kitchen trap. Is this correct?
Attached is a diagram of the proposed layout.
Thank you.
