The ones you've seen in toilet tanks work at house line
pressure just fine -- only poorly adjusted or poorly
maintained ones need to be jiggled. But note the amount of
leverage on which they rely and the size of the float. The
float lever must be able to apply a pressure over the valve
opening in excess of the plumbing psi-- maybe 40-6- psi.
