This weekend I needed to cut the copper supply lines into the kitchen sink so I could install a new sink cabinet. I live in a three family building that has been converted to condos and own the first floor unit. For the hot supply I was able to shut off the feed from the hot water heater and complete the work. For the cold supply, however, I had to shut the water off to the whole building from the main feed.
I completed the work but had to turn the supply on and off several times as I tested the work.
This morning the water flow to the bathroom sink slowed to a trickle and practically stopped. All the other fixtures (tub, new kitchen sink and washing machine) in the unit don't seem to have any problems. Also, I haven't heard any complaints from the other units in the building.
Could the problem with the bathroom sink be related to the work I did this weekend or is it just a coincidence?
