I just started a simple bathroom makeover the other week. When I took out the toliet I found that the wax ring must of been leaking for several years prior to my owning the home.The subflooring was rotted & the rott spread under some walls. One wall is a 2X6 wall that the main drain & water supply run through (the plumming wall?). The sill plate for this wall is also rotted. this plumming wall runs paralell with the floor joist (no support other than the subfloor)so I am fairly sure that its not a bearing wall, but it goes all the way up to the second floor ceiling. My queston, is is this wall load bearing? If not would simply bracing it to cut out the sill plate & rotted subfloor be good enough?
