to turn a 20 minute tank fill valve and flapper replacement into a 45 minute job.

Something always has to come up to increase the hassle/degree of difficulty. Last go-round I evidently put too much pipe sealant crap on the plastic threads and getting the plastic nut off was a nightmare. Of course it's on the left side of the toilet and I have to use a wrench almost the whole way. Didn't help my case of tennis elbow much. At least I got it done and the toilet isn't leaking anymore.
