Is it safe to drain RO waste water into it?
What is this open pipe? Guess it must be a vent? There is bathtub on the back of wall. https://preview.redd.it/nfm4r4my7j4f1.jpg?width=1800&format=pjpg&auto=webp&s=739cb5ff85e73629aa540e992f03813c943d81ab https://preview.redd.it/6ex91vu18j4f1.jpg?width=1800&format=pjpg&auto=webp&s=281cae59001af4ba69d2ae3bc5e7b29fe5a15bb8 Trying to install a RO but couldn't locate a good spot on the sink drain line for RO waste water, which specifies to be above the P-trap. Is it a good idea just to put the RO drain into this open pipe? submitted by /u/AFeiQ [link] [comments]
