My house is about 80 years old and is full of galvanized plumbing that for the most part is in pretty good condition. Alot of this plumbing leads to nowhere though, which for this project is very convenient. Im looking to put a laundry sink in my basement and the hot and cold water pipes both have pipes that lead off of them and are capped at the ends. Im wanting to tie into these and us PVC to plumb my sink. They are 3/4" dia. and that caps look fairly new. Does anyone have any advice for doing this?
