No, nothing has changed
Re-checked it all this morning, had to leave it all unplugged lastnight, same thing, dang tank fills right up to the lip and I have to unplug the pump Grrrrrr LOL too weird. The pump has evolved
I may have to cut in a valve and open it up half way or something to match the drain. Could I do this without damaging the pump?
If it's possible, the removal of silicate within the impellor/area may have allowed the pump to increase RPM's??
It is the only thing that makes sense !
