About Pubco

The Pubco flush valve was manufactured in Australia from 1932 to 2019 and was designed to be long lasting and very suitable for high intensity use. Red Brass castings with 85% copper and 6% maximum zinc content were used to achieve the longest possible service life.

Many Pubco installations are very old and have been maintained by servicing and in some cases rebuilding or replacing some valves over the years.

Consideration should be given to upgrade or progressively upgrade to more modern products at many installations
