OK, this may have been covered along the way by someone else, but here it is anyway. I have my XP3 all hooked up and running, but I was getting this anoying whistling sound. I checked all the connections, and finally found it was the sprayer bar. I put the jet nozzle on for now so I don't have to hear it. But I'd really like to put the sprayer bar back on. Does anyone have a solution to stopping the whitsling that comes from the sprayer bar? It does it no matter how I adjust it or the amount of pressure going thru it with the adjustment valve.:help:
