Thanks oldognewrtick. That's a complicated one for sure. lol. We bought that shortly after the tornado and put it upstairs. It's been up there so long I had forgotten what it looks like. I do have one issue with it though, that I haven't had time to look into. When the toilet flushes the water temp rises. I got a sheet with the unit that shows how to remove/clean the Thermostatic valve, so at least I know it has one. I'm wondering if it's maybe stuck from sitting in storage so long? (about 3 years) I've never had to work on one, so I figured the next chance I get I'd just watch a couple YouTube videos. If anyone has any suggestions on what to look for, I'd appreciate the info.
