–Turns out Grace’s faucet installation by Ross Broadley was kind of rushed. He had the escutcheons on backwards (mine too) and hadn’t tightened one of the fixtures sufficiently, so it rotated. I fixed it all up. Sure hope those valve seats (which he didn’t replace on the shower) weren’t needed.
–Took Grace for big shopping ($200) at Bel Air.
–Went to re-pot a new sage/rosemary/thyme plant from Bel Air and noticed that the sprinkler valve was dripping, around once/second. Spent a while trying to figure it out–got one of the caps off-but gave up. Too old/unfamiliar/painted over. Called a guy I got from nextdoor.com and he’ll be over tomorrow to replace the valve for $185. Expensive, but super-quick, and I should be able to learn all I need to know for the other two valves.
