Hi all - I hope someone can help. I have a roughed in bathroom in my lower level (concrete slab floor). There is a tub dap out (horizontal 2" in a 9"/12" hole in the slab). Whirlpool drain will be about 3 1/2 ft. from the hole in the slab. Is it within code to raise the whirlpool about 6" (on concrete - so a trap will fit), trap directly under the tub waste outlet, then run horizontal 3 1/2 ft. and connect down into the hole? The run will be under the tub deck, so I can support it any way I need to. There is also a 5" or 6" (big) vertical drain pipe about 2 ft. from the tub waste opening, where all the upstairs (2 full baths) drain into, it also vents out the roof. If I can't connect down into the hole, can I use the same setup as above and tie into the vertical drain (tee or wye). For either, will I need to vent it separately.
House was built about 9 years ago with a toilet, the tub dap out, and a vertical vanity drain/vent (in addition to the one for upstairs - 2" drain 1 1/2 " vent). As a last resort could I break out concrete (ouch) from the old tub stub out to where I need the new one and run a horizontal 2" and trap right into there? Again, would I need to vent this separately?
