VALVE MAINTENANCE
Hard water conditions may results in scale deposits causing
binding of internal parts in extreme cases. Cleaning the internal
parts will usually restore the valve operating conditions. In
some cases it may be necessary to replace the lower assembly.

assembly, diffuser and spring.
WARNING
Do not use solvents or scratch metallic / Teflon
coated surfaces.
4. Carefully remove any scaling (calcium deposits) or
foreign particles from valve seat and other internal
parts. Use vinegar to remove calcium. Soak parts until
calcium becomes soft and can be scrubbed and
washed off.
5. Replace cleaned spring, diffuser and lower assembly
following instructions below or use new replacement
kit assembly.
