slp outputting 500psi?
So I picked up a slp pro tank/reg a few Weeks ago, the other night for ****s and giggles I hooked it to a pressure tester (asa with a gauge) and the reading was well over 450, almost 500. To check the gauge I hooked 2 other slp tanks and a shp tank and they all read the proper readings. I have read the slp is unadjustable. Can anything be done? Also the only thing I adjusted was the reg collar.
