New auto fill too sensitive?

[Toxophilite]

The fill line does run horizontally into the back of the unit. On the brass units, it is also nice that the water rushes out downward out of the bottom spigot, so you also get less of a hissing noise when it fills. I noticed that the vertical arrangement does not have as many options beyond the traditional toilet float setup.

Yep! I don't have a brass alternative in hand to check dimension, but had thought if room enough I could plumb internally from the bottom up the side of can to a horizontal fitting.
