I have a drain problem with two possible solutions. Any advice would be greatly appreciated.
1. Replace leaking under-slab sink drain by tearing up floor/cabinets/walls through entire length of kitchen, cut trench in concrete slab, replace broken pipe (and water supply lines in same original trench on top of leaking waste line). Patch concrete, install 300 sq. ft. new flooring, reinstall cabinets and (probably new) counters.
2. Abandon old drain in place and install new drain outside along exterior wall, properly sloped, concealed below wood deck conveniently located on other side of exterior wall directly behind the sink and at the perfect height to conceal the drain. This would run about 15' outside before turning back into the house (where there is a lower level) and connecting into the waste stack at the original location. Basically, just offsetting the pipe around the slab instead of under it.
Can anyone weigh in on code issues, freezing issues? Would I need heat trace or just insulation? It can get below zero a few times a year here in the Midwest.
