It turns out the plumbing problem was both inside and out, but mostly within the house, so I called the warranty folks before the job was finished, he told them what the problem was, and they'll pay above the co-pay amount. The plumber didn't write that he also ran the line outside to the street so they wouldn't quibble (since I have to scan the invoice and send it in). Nice of him!

Now to mop the laundry room floor (I ran the washer as he ran the snake and it flooded again before the job was finished). A pro tip for future maintenance - he said run hot water in the kitchen sink for a few minutes then put a big squeeze (~ an ounce) of Dawn dish detergent in and let it run a little longer before turning off and letting it stand in the pipes for a while. The heat and the soap will keep a grease buildup out of the line. (Repeat a few times a year.)

The dogs were in the backyard for this service call, so as the work moved to the side of the house they could see us through the back gate and set up a ruckus. I explained to Randy the plumber that if we said hello they would settle down, otherwise they'd bark the entire time. They were thrilled to meet someone new, he likes dogs so gave a couple of pats through the gate, and they quieted. It's their job to watch the house and yard, so the courtesy of an introduction acknowledges their work and they know I'm safe.

Now I have some laundry to take care of.
