About us

32 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 geyser ancillary product manufacturing business in South Africa, a proud platinum member of IOPSA, and a “Proudly South African” member. 

In 2023, Advanced Valves was voted IOPSA’s Manufacturer of the Year by members of the plumbing industry.
