Copper pipes are unrelated to environmental hormones and possess many special qualities used for welding, hygiene, cost, anti-corrosion, anti-freezing, anti-earthquake purposes. The European countries have long known about these superior qualities and have thus employed them as the piping material for hot and cold water. Even in Japan, most of our hot water pipes are either made of copper or are plated with copper.

However, the use of copper pipes in cold water is still limited, due to the availability of cheap plastic pipes and misunderstandings stemming from fear of the toxicity of patina.

These days, in high-rise buildings with direct water supply, light-weight and malleable copper are highly suitable for use in cold water pipes. By using copper pipes for both hot and cold water, one can also expect an increase in efficiency.

This page is meant to be a reference for those of you who are involved in waterworks and attempts to look at the issue of copper pipes from various angles. It is our pleasure to use this opportunity to introduce to you the superiority of copper as a piping material for water.
