Welcome to homeownership

We have had an exhausting and emotional day today--it was moving day, plumbing day, appliance delivery day, and cleaning/unpacking day. Jason and I spent almost all day at the house and we actually got a lot done. Now we have more empty boxes than full ones! And so far, all of our stuff is accounted for.
We had a traumatic welcome to homeownership. Last night when we were at the house unloading boxes, we noticed a leak from the ceiling into the middle of the great room--a pretty steady leak. We turned off the water, poked a hole in the bubble that had formed, and forced all of the water out, then went home to cross our fingers until morning. This morning, our plumber told us that the only way to a) diagnose the problem and b) fix it, would be to rip open the ceiling to get to the pipe. My jaw dropped. I was afraid to even think how expensive that would be. But after turning on all the faucets and flushing all the toilets, the bubble wouldn't leak at all, so the plumber recommended that we just forget about it until it happens again. Then he went in the crawl space and found $1200 worth of repairs, including a broken regulator and a cracked pipe that was spraying water everywhere.
After he did his work, he came back to look at the bubble some more. It still wasn't leaking, and he went outside to look at the side of the house. He noticed that the dryer vent had pulled away from the siding of the house and that it was directly across from the bubble in the ceiling inside. So, it looks like probably the problem came from water leaking into the gap between the vent and the house and seeping into the ceiling. That is very, very good news, because we just have to silicone seal around the vent and hopefully that will be the end of it. I hope it is
