On these valves, the seals can be replaced, by removing the
spindle. Just checked with Pegler, £1.34 per O-ring! I have
several old valves to maintain. Does anyone know of any similar O-
ring that may work OK? - I don't know the exact size. I would not
think the material is that critical, only water and Fernox in the
system. Any advice much appreciated, thank-you.
