I was changing a valve for my brother, it was located low in the basement so to be sure there was no water in the pipe near the solder area, I used a long compressor nozzle to blow out any water in the vertical pipe.
When I removed the nozzle, it was covered in sludge.
This can't be good, or a normal thing in the potable water line?
Has any one seen this of have any ideas?
Thank you,
