The Bitter Mod
Is there any harm in restricting the output of a Mag7? I was thinking of putting a ball valve on the return line from sump -> tank.
Youre partly correct! If you restrict the pump on the intake, that is when you are making the pump work to hard and it will have a shorter life. Restricting the output is just as stated above, mechanically adding head pressure.hng said:I would think that restricting the output would shorten the lifespan of the pump and cause more heat output. I could be wrong though, cause I've never done it, but it seems like that would make sense
