So. Things I have learned today include the fact that neither of the two stopcocks with which I am familiar affects the running of the outside tap. There may very well be a third, but I have no idea where to begin looking for it.
Which means that if I am to change the washer on that tap, I am going to do it wet. Wet and cold. I know this is possible, for I have seen it done; just, not in three feet of snow. Brr.
I am quailing a little, I confess. I have the tools, I have the knowledge; I have less than an hour's daylight left. If I'm going to do it today, I need to do it now.
Or I could just leave it till tomorrow. Or the next day.
Except that last night it was really getting to me, lying in bed listening to the sounds of water in the pipes. Mostly I listened to the cricket, but I could still hear the water underneath.
The good householder ought not to put things off. And I'm going to have to do it sometime; might as well be now as then.
Um.
[ETA: Damn. I was overconfident. I either lack the tools or the skillz: it's a manky old tap, and I can't shift the valve. Not with my cheap adjustable spanner, at any rate. Grr...]
