 put it all back together again, it worked perfectly the first time, and I'm totally good to go. So I think proactively replacing the toilet tank valves is really a smart thing to do. And when you use the Everything Toilet Tank Repair Kit, basically, you know, you're going to have everything you need. $30, I was done, no chance of leaking, we're good to go. Is any of it like a tough job, or can anybody tackle this project?
