Recently, my husband and I were fixing some water pipes. We used white bread to stop the water when soldering. Unfortunately, after leaving the shower valve open for more than four hours, there is still only a trickle of cold water. The hot is fine, as well as all of the other hot and cold in the house. The only problem is the cold in the shower. Could it still be stuck in that valve. If so, what can we do short of digging into the wall and cleaning out the valve?
When my husband got home, we turned off the house water, hooked up the garden hose and opened the cold on the bathroom sink. It dislodged whatever was stuck (possibly a small bit of sediment). Thanks!
