The product worked great. Unfortunately, I guess I was not ready for DIY plumbing, and an invisible leak led to literally thousands in water damage within one day. I wrote in with my sad story, and Tushy sent me a few rolls of TP as consolation.
Cautionary tale / tip from my plumber: 1. Make sure your renter's insurance covers water damage caused by YOU, in addition to damage caused by others. Lemonade f*cked me on this. 2. Using a piece of dry toilet paper, run it along the length of the plumbing pipes you install, and if it gets wet at any point, find that leak and tighten that nut!
