Gene does it have a allen wrench adjustment on the end and a little hose barb coming off the bottom of it? Some do, you can usually just adjust it in a 1/4 to a 1/2 turn. and it will be OK. My pressure pro 8gpm has the adjustment. I have had to turn it in a few times over the past couple years it finally maxes out. In a pinch you can actually run it with the water spraying out, but you may get SLIGHT pressure lose. I just put a 1/4 clear braided hose on the hose barb coming of it so the water wouldnt blast all over the maching
It can also be a bad blow off. I had one that was new and just kept blasting water I changed it and it was fine.
