Slab leak fixed. With a lot of help from a friend (thanks!), I dug the “pilot hole” for the plumber to tunnel under the house to fix it without destroying the tile in the kitchen. This saved us a few hundred dollars. Then it rained, so yesterday I had to get most of the water out of the hole with a bucket, rope, and a heavy rock. Then I replaced some of the dirt (they replaced most of it), which saved some more money. So that’s more physical exertion in the past three days than I’ve done in many years.
