some of the fancy waterers can really be annoying.
i got plastic ones, as the metal ones always precipatate up real good.
at some point, i will get the waterers that DL has, the little ball float ones that the animal noses the ball down. keeps out mosquitoes and shades the water better.
i have water at 120 psi, obviously not domestic, though on pressure alone, you would need a reducer down to 60 psi for that. i put an adjustable reducer on, and squeezed it down to 20 psi so the shutoffs would work. too much pressure and they always have a small leak, which, in the barn can be kind of annoying.
