I got my hot springs pulse up and running after replacing the jet pump 2 shaft seal. I noticed that some of the pump 2 jets weren't working that well. There were left and right pairs where one would work great and the other would have hardly any flow. I looked up how to remove them and I found that there were a bunch of rubber pieces clogging them. I took them out and now the jets work great.
However, I put all the pieces together into a single object, and I can't figure out what it was. Was this some rubber part to the hot tub pump system that got dislodged, or was it just some random object that got sucked into the filter standpipe when the cap was off? Album:
