well that was a waste of money.
guy comes out, very professional, fiddles around back behind the toilet, confirms the wrong fitting used, should be NPT but he could do nothing until toilet was pulled out.
I thought about this, and said no, I'll do this when I get home, since I need to carefully winterize it anyway. Turns out I had the right fitting in stock, for a pex hose, so all I have to do when I get home is pull the toilet and replace that water inlet line with enough new pex that I can hook it all up first, then install the toilet.
pretty sure they installed this toilet and then tried to hook up the water lines. And since they couldn't see what they were doing, when they tightened that connector firmly, they could not see it was doomed. Though even I can look at npt thread and see it's different than what I call garden hose thread, much finer pitch
after the tech's mumblings that this will take a couple of hours to get this out and in (@175)
basically it was do i want to spend 500 bucks on this?
no, not when I know how to fix it. Just can't do it on the road when
I really need that toilet to work.
so he handtightened the crossthreaded fixture once again, thankfully originally done with lots of teflon tape so at least some of that gummed up the misaligned threads. That original connection lasted up to Michigan and back, OBX and back and finally let loose on this trip.
out of sight, out of mind.
no more. Have pex tool, will fix.
maybe with some expert advice...
