Came home and grit my teeth, ready for a fight with WD40 and sweat and anguish to get the old fittings off, because Arizona has water so hard you can walk on it without Divine Assistance, but to my surprise, the connectors came loose easy once I had the right wrench, and I took off the old and had the new attached in about fifteen minutes. No leaks, and it's all nice and tidy under there. Unfortunately, the sink's still draining very slow, so the clog wasn't in the elbow, but it must be past there, possibly out in the yard. I wonder if there are roots in the pipes (erg). But it was a quick and cheap repair, and I'm so glad.
I filled the bird feeders, pulled a few weeds out by the alley (the rain caused the explosion of weeds along the fences and curbs here), and cleaned the living room. Now... finish the kitchen and try to find a good new place for my die-cast car collection, since the old VCR is giving up the ghost and I had to detach it from the TV last night -- I don't know what causes old VCRs to trick out the color/sound on the TV. I get a green glow and a slight buzz when VCRs get old. When it happened in my office, I thought it was the TV, until I detached the VCR, so when it happened in the living room, I knew right away what was causing it. Since I can get a new machine that's even nicer than the old 4-head at CostCo for $50, I'm not overly concerned.
