10' sink drain run without a vent? OK?
Posted by dj jasper on March 02, 2003 at 17:33:41:

I want to install a half bathroom in the basement. There is already a drain in the floor for the toilet. In order to tie into the stack to drain the sink, I need to run about 10' of pipe with 2 90 degree bends to follow the wall. There is no place to tie into one of the vents in the house. Will this be a problem? Should the drain pipes have standard slope? Thanks for any advice. DJ
