In April 2012 we bought a Stiebel under-bench water heater, which needed a Pressure Limiting Valve in the supply pipe. This is made of brass and has recently developed a pinhole leak, dripping into the cupboard below. The plumber identified this as “the Cashmere problem” and has suggested replacing it with a new plastic model. Much more expensive!
Our 50 year old cylinder has yet to give trouble. Wait and see!
We live on Hackthorne Road
Concerning the Cashmere HWC problems, I would like to have my posting removed, as the problem was not corrosion but a loose fitting. When screwed up tight, the problem disappeared. It was a very awkward place to reach with a spanner – hence the problem!
