I am tired to replace the crappy toilet fill pipe-float-valve.
They are high tech, made of minute plastic parts that get slimed and warped
in a few years. The old brass stuff lasted longer than the mortgage.
The rubber flap is another sorry thing, there must be a better type of
rubbery material that what is commonly used.

Has anyone a suggestion for suppliers of good quality tank valves?
Will a real plumbing supply have anything better or is the same HD stuff?

Thanks
