I know there are a few knowledgeable plumbers on here. Hopefully someone can shed some light on my problem.
Last night, the cold water in my bathroom stopped working. I went upstairs to get ready for bed, went to brush my teeth, and nothing. Hot water works fine, but no cold water. Same for the bathtub, shower and toilet, but everywhere else in the house is okay.
Possibly pertinent details:
- there's no flow at all... not even a little bit. When I open the faucet, I don't hear anything; no gurgling, no flow, nothing.
- everywhere outside the one bathroom, everything works just fine: good flow on both hot and cold with no change from before.
- the house is about 10 years old, so all the pipe is copper in hopefully good shape; no galvanized or anything like that.
- it got really cold yesterday, though I don't think (or maybe "I hope" would be more accurate) that the pipe to the bathroom is in an outside wall.
- I didn't notice any water problems prior to this. Yesterday morning, I had good flow on hot and cold, but yesterday afternoon, nothing on cold.
- the shower acted a bit funkier than the other fixtures. At the sink and the bathtub, I have good flow on hot and nothing on cold. At the shower, I now have low flow on hot and nothing on cold.
- I don't think it's leaking in the walls or anything like that. There are no signs of water below the bathroom or anywhere I think the pipe might run, and with all the taps in the house shut, the water meter doesn't move.
I slept on the problem and came up with an idea this morning. Assuming that it was a blockage that might be dislodged, I closed the shutoff on my water service at the meter and drained down the water level in the cold water pipes at the basement laundry tub. Then, I opened up the bathtub faucet upstairs and opened the shutoff as quickly as I could, hoping that a bit of water hammer would work it loose - no effect.
So... it seems to me like it's some sort of blockage, but the question in my mind is what kind of blockage and what do I do about it? Has anyone run into anything like this before?
