Maybe.

Okay.  It looks like my first shot, at the hardware store, was more correct.  The problem, however, is beyond that.  What I had thought was galvanized steel may actually be cast iron... or very old.  Why?  Because though they really are both 1 1/2", but they don't quite thread.  It's just a touch off.  Why?  To make sure hacks don't simply connect them.  Why?  Because then they rust off so fast a construction company could be sued out of business.  That's why, I would guess.

The flange will fit though.  I will just forgo the extension.  The only thing I need from the hardware store, other than returns, is the abs/foam pvc pipe cutter for 1 1/2 inch pipes.  I simply do not wish to tinker with trying my hand at cutting a straight cut, with or without jigs.  Even jigs have to be used correctly, and take some learning.  I only have, perhaps, eleven or twelve feet of pipe.  And, yet, a few bad cuts can eat that.  I need some of that in for the washing machine drain and some for the size down and coupling under the sink.  Is it the right stuff?  It's all that I can find that fits and works... unless I wanted to completely redo the drain and other piping...  So... yeah, it's the right one!

I called to make sure.  Being this close to Christmas, it is difficult to know if the store hours are right.  Phone message systems fail, get it wrong, aren't put in correctly.  So I found an actual human with whom to speak.  Though the phone was so bad it was like talking through the old fast-food mics and hearing on those old speakers.  I "think" I heard that they are open and they do have the tool I am seeking.  However, while there, I will probably look for a few 18 tooth per inch blades for various things.  Just... in case.  *sigh*  Yeah, I... prefer to have options than just bad luck.

It's 16:00.  I have until 21:00.  I need a shower.  I just do.  Then on in.  My goal is to have all of the pipework cut, fitted, and glued tonight.  Letting it cure overnight should be enough, but I might give it two days.  I will pull some water... or just buy some as I think the sink is... it would be a mess to get water at this point.  I have a gallon of tea stored, but a couple gallons of water and milk would easily hold me over for a few days.  I just drained all my emergency water, remember, and need to clean the containers, then refill them, before I have that extra water for these things.  Ugh.

Well, I best get going.  Good afternoon.
