| Re: adding another sink in bath Good morning Brad, Yes to both questions. For the water you will need to change out the old compression angle stops to 1/2" compression angle stops with double 1/4" compression outlets. Keep the old 1/2" compression nuts and reuse them. For drainage you will need a continuous waste to tie the two lavatorys together and discharge into your existing "P" trap Hope this answers your question. More questions? I'm as close as a click. Cheers, Tom |
