Why do people buy expensive ATO?

[Paul B]

I don't know what any of those commercial ATOs are. I use gravity and city water pressure, so I use no pumps and so far gravity hasn't failed me. :beaming-face-with-smiling-eyes:

Asks if people use an expensive ATO... uses a $600+ Neptune Apex system for ATO ;)

Haha, fair point! Guilty as charged. But honestly, the Apex was already there pulling other duties—I just DIY'ed the ATO instead of dropping another $200+ on top of everything else. And let’s be real, I wish the damage was just $600! I’m genuinely curious if I’m missing something magical , so I figured I’d ask.
