We have lost them due to last night backup power dry run activity. Personally I would say our system are very flexible under any power outage situation.
However, when humanity is involved, the thing will screwed up easily whereby during tightening up a pvc pipe from main tank to the taller tank, the impatient old fart(which is i) had not follow the proper procedure PERIOD
And this is unacceptable... TOTALLY... ULTIMATELY.... Or PUT YOUR FAVORITE WORDS HERE...
