Frustrated with Vortech

[kwirky]

sounds like manufacturer defects. I'd recommend taking it back to whoever sold it to you or deal with the manufacturer if there's no in store warranty.

I screwed up my vortech's impeller because I ran it on the wrong glass thickness. An exchange of the impeller/prop part got it working back to normal. (ran it on 1/4" when it was 3/8" glass or whatever is the next largest thickness)
