Anyone else had this Fluidmaster issue? Any solutions?

On a really slow filling WC (tank fed, pathetic pressure) sometimes I find they struggle to shut off. As if they need a little bit of grunt to close. With a really namby pamby fill it just keeps creeping in....

Had a few faulty ones recently - annoying as they are usually the dog's nads. Replacements worked fine even on gravity.

Yeh, had one the other day where where if you ran the cold tap in bathroom it made the wc inlet valve run, just change the washer and all was good (touch wood)

Had two last week both on gravity, always fit brass shank fluid masters thought they were great. ended up fitting the new brass shank torbecks and all was fine, glad to know it wasnt just me. One to remember!
