LF Opinions on ATO Units

[gregzz4]

I've been using 3155s for over 7 years without issue. I've only ever had issues with 1 unit and the controller was swapped for a new one @ the place of purchase. Unit would freak out, even plugged into a surge protection circuit.
Replaced and problem went away.

I have 3 of these units and all are reliable as all get out. I keep a spare or 2 pumps around just in case. I got 5 years from a pump before deciding to replace it due to some noise, but it kept working right up until it was replaced.

In 7 years on 3 units I've only replaced 1 pump so far.

I do NOT use Kalk in my ATO - only RO, and never let my pumps run dry.

I installed a relay circuit to protect my pumps becoming dry.
