Hello awesome folks of AutoCareforum,
It seems like every month I need to change the little plastic O ring on the high pressure valves on only one of my pumps since it keeps loosing pressure (this morning it was about 900 psi vs Normal of 1200psi) and also vibrate a little bit. First I thought the high pressure seals need to be changed but as soon as opened the high pressure valves saw that all the O rings are broken. So changed the O rings and BINGO back at 1200psi. But why this pump keeps breaking O rings?
This might help to answer this problem: Pump pressure is at 1200psi when the handle is squeezed, but when the handle is not squeezed the pressure is on 1500psi. to me this is a big difference, and perhaps trying to tell me something.
