Busted!

Welp, here's the culprit in the living room waterfall:

A blowout in the pipe under the floor in the upstairs bathroom.

The sink was taken out weeks ago and the flooring had to be taken up to access the pipe.

1st Day, 1st Disaster

In a 176 year old house, you don't know quite what you're getting into. No idea what works, what doesn't. This being the first full weekend with the house, a number of basics needed tending to, including turning on the water. And everything was just fine for about 20 seconds. Followed by modest waterfall cascading from the living room ceiling. 

 It would appear that after 2 years of sitting vacant there are a few broken pipes that need some attention. Best guess: that wooden beam conceals a pipe leading to the bathroom directly above and is obviously no longer in tact. And that wasn't the only leak. Plumbers will be called in the AM.
