I don't know the first thing about plumbing. I am hardly even capable of unclogging my own toilet. I did watch one of my relatives add new piping in one time, and I did go with him to buy the parts that were needed.
We even had to go back because we realized we needed one more part. Check out Austin plumbers.
It was interesting watching him fit the pipes together and use the PVC glue.
I wouldn't be able to tell you what was done or do it again after it was modeled for me, however, because I'm just not a handyman, that's for sure.
