it it was me, id be questioning an
ATO at 55feet away, thats a pretty long way.
You'd want a pretty hardcore doser.
A simple flood & drain network system would be a cheap option. a pump in the
RO vessile, 2 floats, high & low in the end capture container so its primes itself near the tank. Then allow your
ATO to handle the duty from there as its more incrimental.
