Spare Part to replace your old worn or damaged washer
THESE ARE THE NEW STYLE WITH THE EXTRA RIM ROUND THE BACK
Replaces the diaphragm washers from the SV81767 & SV80367 Inlet Valves
Once this washer wears or splits it will cause the valve to malfunction, either stopping it from filling up, not shutting off or filling up very slowly.
A new inlet valve can be costly so why not try a washer first?
