Recently we had an outside irrigation system installed. I wasnt home when the contractor did it but my daughter said he asked for a couple of slices of bread when he was closing off the water lines to install a new line going outside. Ever since, one facet in our upstairs bath just dribbles out a small flow. When I called to ask him about it, he said it was probably one of the pieces of bread (not sure what he used it for) and that once it disolves, the pressure will come back. Its been a few days now, and although we have seen a slight improvement in waterflow, its still not at the level it was before. Is he right, that we just have to wait patiently for this blockage to clear, or is there a quicker solution? Any comments would be most appreciated
