Half of it, and the more difficult half I think.

It's not just turning things to tighten threads, or sizing, or cutting, or taping.  Sometimes it is doing those things upside down because it is the only way to do them.  Then going into a closet, then shrinking the closet to half, then quarter, size.  Taping, and twisting, and measuring, and pushing, and holding, and... it gets to you.  But I didn't want to stop until it was done.  I know what that means for me... it can kill a project.  So I finished.  I put a bucket under there, just in case, and pulled almost a gallon of r.o.  At that moment, and for a few moments after, all seemed good, and dry.  Who knows.  I won't for days, and I won't be more sure for an half hour.  I am now going to drink that water.  Thirsty!

I really think the washroom plumbing will click together in a hurry.  No fittings to screw in, no tape to wind, only one set of bolts on the flange to secure.  The rest is just cutting to length, and really that is extremely variable, almost more to my taste than to real world demands... mostly.  A few cuts, a dry fit of the whole thing, then disassembly, cementing, refitting, and then just letting it cure for the next two days.  I think I can, finally.  If I've got this, I might actually call in a plumber to help select, then install, a high kitchen faucet, take a look at the drains to see if there is a problem or minor fix that could help, check the water softener.

One thing at a time.  Only so much I am willing to do.  Sometimes pay, sometimes diy, and I'll get further along through these things.  A few more pain killers, but no more until I am back to work.  If it hurts, I either get to ignore it or take a nap through the worst of it.  But it does look like I will get the piping done.  Not the leveling, but, one a day for the days after Christmas.  Until I get them, then just... time off... a week, or really as much as I need.  Quite a run.  I honestly hope I can get back to work very quickly and keep at it for... a longer period then since before I was ill.  The goal, pretty much, is to get back to doing what is needed, when it is needed, at a much quicker pace, success rate, and all such.  Who ever knows though.  Later.
