Good news! I found out what was keeping water from going to Landlady's house, and it didn't have anything to do with that big broken hydrant!

Bad news! Uncle Joel must have been dropped repeatedly on his head as an infant, for that is the only rational explanation for why he forgot all about that perfectly visible valve he had to lean over to putz with the hydrant - the one that shuts off water to Landlady's house!

Good news! When I opened the valve, water immediately and copiously became available at Landlady's house!

Bad news! This was so immediately apparent because of the broken elbow that spilled that copious water all over the closet floor!

Plumbing. Winter. Sobriety. Hate them. Looks like it'll be a pretty easy fix, though. Assuming the plumber didn't use up all my fittings. Which, given my luck...
