OK-- I will try to keep this short, but I need some advice, *please*! I have a 3 story townhouse. This morning when I got up (at around 5 AM), there was no water. Unfortunately, when it gets really cold, on rare occasions, the pipes freeze. Clearly this is a huge drag, but I hopped in the car, zipped over to BF's house, showered, and still got to work relatively on time. Unfortunately I had OR all day so I couldn't sit around and wait for the management company to come earlier. This afternoon, I called the management company and asked them to take a look at the pipes; it hasn't been much above 0 today so I figured they were still frozen. I got home around 5:30 and YIKES there is water everywhere on the first floor-dripping from my ceiling, down my walls, even in my garage. Amazingly, despite the fact that the rugs are wet, somehow nothing of any value got dripped on (my new Miu Miu and BV shoes were spared, thank goodness). On the second floor, my kitchen sink had overflowed and was pouring water all over my kitchen, into the living room and dining room, and I guess to the ceilings below. So the property management people came over and investigated--it doesn't look like a burst pipe because the water is working fine and once I emptied the sink, things were better; they think some back pressure forced the sink valve open and the water on (??is this possible? I don't know!). I already called the insurance company, and took pictures; as I said, the vast majority of the damage is limited to the house, so I'll probably need some ceilings and wall drywall replaced and repainted, but my things (except a leather sofa) are all OK, for the most part. And the mitigator people (people who dry water up for a living) are coming over tonight as well to fix this up--apparently this takes 3-5 days. Has anyone had this happen to them? Do I need to do anything else? Should I be more worried? Should I call a plumber? I'd prefer not to since I don't want to pay for them when there is no broken pipe, but on the other hand, I don't know what the problem is or how to fix it. I know I didn't leave the kitchen sink on, because I left the hospital at 1 AM this morning and just climbed into bed (and the water was working, so I would have heard that running--random water running drives me crazy). Please help! I need some advice. The insurance company says it will be fine, but we all know they're FOS. What about when I sell the house? Do I need to disclose this? Thanks in advance. Please feel free to keep me company while I dry out.
