The idea was that on March 11 each year, everyone should stop and think about what plumbing does for them. It improves their own health, and way of life. All over the world, countries are doing this all day long. World Plumbing Day was created to help us appreciate the many roles of pipes and plumbing in our lives. Take a little time to think about the role plumbing plays and as we do, it only makes us more grateful for what they do.
