:huh: I am trying to add a second bath to my home. For the first time Im planning to carve up a section of the concrete block slab and dig down three feet to my sewer line made of pvc to tie into. I intend to use a skilsaw with a diamond tip blade and sledge hammer the concrete out after that to save from hiring it out. My questions would be: Can I tie into the existing sewer line with a 90 degree angle without back up troubles? When I cut the floor will I hit rebar and I assume its ok to cut through it? Is the concrete about 4 inches thick like I think it is? And is it ok to have such a steap slope from the new bath toilet flange down three feet over a six foot distance across the room. Can I tie in the toilet new sewer line and the new shower drain line both at that 90 degree curve down in the floor at the main sewer line three feet under ground:huh: Or should I Y them off farther above that point? Help!!
