I have a liquid levelers hydro pump that I am rebuilding, new O rings, replace broken vac. Gauge. I found in one of the boxes of spare parts a bag with some very small ball bearing between 1/8” - 1/4” in dia. I haven’t found any of these installed during the tear down. So I am wondering where exactly they are used? Perhaps as part of a one way check valve? Any information would be appreciated.
