by adjusting the valve from to pump is not the best idea.it just put extra pressure on the pump which will cause premature wear f the pump..
the herbie style is absolute quite,dead silent, and if is done correctly it is 100% safe.you need to have the emergence drain which you have.i have this system on all my systems and never had an issue,in case you have a snail trapped in the valve the emergence drain will carry the water..i have this system for 2 years and never had it clogged.and the other advantage over the dorso pipe is that you have 0 air going in the drain ,whit the dorso you have some noise from the air being sucked in the pipe..and because you have the sump in the basement it will be no noise from the pumps and skimmer..this is just my opinion.
