Aaaaaand HOooOooRRAaaY! That was it! After days of worry, the leak is fixed!
So leak update: so far there's a cracked poly pipe elbow about 8 inches from the actual water meter, out by the front fence. You couldn't write this! Fingers crossed it's the only leak, they think it is...

Hooray, the plumbers are here to search for the leak! Fingers crossed, everyone, please ...
