Dear Readers,
My locality recently switched to the I.P.C. I want to tie in a washing machine on the basement floor to the 2" drain/vent for my kitchen sink. Can I re-vent the washing machine (basement) above the drain for the kitchen sink (1st floor) and be OK with code or will I need to put another hole in my roof? Thanks for any insights. It seems like reventing above the drain should be fine, but it's not very clear to me.
