Hey all, Redoing my laundry stack, fixing all of the previous owners mistakes. House was built in 1959 with a cast iron p trap buried under the concrete. It’s eroded, leaked, clogged, and causes the washer to overflow. Plan is to cut out the old p trap, use a fernco to a long turn 90 to get vertical. From there use a sanitary tee to go back horizontal, using the top of the tee as clean out access. That will go back to a 45 like there is now to get parallel with the wall. See any major issues or changes for the better in the way the rest of the drain/stack is put together now? Suggestions? Thanks!
