You never put a valve on your drain line unless you have a back-up drain.

Whats the problem with a valve? Ive done that on plenty of tanks, works great!
If you close the valve to much = you will raise the tank level and starve the sump pump.
That might also cause an overflow in the main tank, but most sumps dont have enough water in the final baffle area to overflow the tank.
Unless you have a 30 Gal. sump on a 10 Gal. tank?
You can adjust the valve by closing it slowly until the pump starves and opening it back up until you get the desired sump level.
Either way, hope this helps.

They are only rated that way if installed vertically (bottom of tank) If you run them horizontal expect far less, like nearly half un many cases.

+1 Not to mention the constant battle against flushing and gurgling.

AAARRRGGG my old nemesis on my last 30g tank (set-up for 10 years). That thing was how I learned all the damn little tricks to lesson the noise.
