Tunze 9020: Roger Help!

Roger:

I have a 9020 skimmer than I have been using for some time now, and was having a lot a difficulty with one of the two skimmers from the start. One side is just not pumping as strongly as the other. I can tell because no skimmate reached the top of that skimmer, and the water does not flow out from the standpipe nearly as strong as the other side. I read all the threads I could find here, and took the skimmer apart and reassembled it back too many times that I have lost count. Finally I noticed that on the impeller of the weaker pump, one of the two small dark grey "brakes" is missing. By "brakes" I mean the approximately 5mm x 5mm ridged squares that I think force the impeller to spin one way and not the other. (I hope I am clear; I do not know the technical name of this part).

Do you think this missing brake would cause that pump to underperform? If so, how can I get a replacement part? If not, what else can I do? I have checked the verturi (it is fit snug for sure) and the bottom cover is seated properly, and the standpipes are not forced in too far, etc. etc. I sincerely appreciate your help. I have spent a small fortune for this skimmer (plus a lot of shipping to get it to Hawaii), and I just want it stop having to fiddle with it anymore and have it simply work.

Aloha,
Stephen
 
Yes, this missing brake would cause this, the impeller will slip and not spin as fast as it should, eventually it won't spin at all. PM me your address and I will send the parts.
