Option 2: bad

Please explain why is it good, or bad?
if your return STOPs cause of the valve... the tank basically reacts the same was as a "power out" scenario...
if your overflow stops cause of the valve... you sump is pumped into the tank and onto the floor...
You can and should put a strainer on your return pump input which eliminates "stuff" from clogging on the valve...
You should not put and typically dont put a strainer on your overflow (a fool-proof one) which means it's typically possible for snails / hermits to go down.. and get caught up on a 1/2 closed valve.. bad mojo (see above).
or a fish (happneed couple times) lol
Well if you would elaborate on the setup then it can either be good or bad... If there is only one valve in the setup then it's bad because it is putting stress on the pump by holding back its full capabilities. Now if you were to " T " off the return line and have one valve returning into your sump then that is OK because you can control how much flow you want to the tank by adjusting the sump valve accordingly... If that makes sense ?!
Im sure these new pumps on the market can handle the pressure
we should ask the pumps compagnies what they think about the subject

Reeflo told me, when I was designing my closed loops, if you put restriction on the input side of the pump you'll burn them out quickly. It was recommended that I put the valve(s) on the output side.
One more thing, going to a digital pump is an even better solution... Dial down the horse power and the wattage, instead of choke it back with a valve. I've been eying the blue ecco pumps myself...
OOOOOOOOO, AHHHHHHHHHH! I know what I whant for xmas :)
