Phew! See? Long list.
Jordan and I had to find the city shutoff within the house when we removed the old kitchen sink, and we were left with a drip, drip, drip that was filling our giant red bucket once a day. It took a week or so after that before the plumber made it in and was able to address the problem, but the good news in all of that was that we learned where the shut off was, what to do if it rusts/breaks and the phone number of a good plumber. It didn't, break, but we were told to be prepared for it.
Here's a couple of shots of the bathroom. Our pretty new plumbing, and our tub! So lovely!
