About us

27 years ago, Richard Wiederhold started a geyser valve maintenance business in Johannesburg. Through the knowledge and experience gained in manufacturing, Richard discovered that technical polymers are as good as brass but cost way less, and that engineering plastics is the way forward. The business evolved into Advanced Valves, which is now the largest hot water ancillary product manufacturing business in South Africa, and a “Proudly South African” member.
