Our four-story apartment building does not have a shut-off valve for each individual apartment. Whenever we need to fix something we need to turn off the water main. Afterward, the water is always dirty. Is there a simple way to flush out all the dirty water by turning on only one unit instead of flushing all the units? My logic says I should flush from the bottom unit. But it did not work.
Thanks.
