My DS has been squealing during shots lately, and Ive been wondering what I can do to fix it. I saw this post on HB:

"Its a simple fix. First take the valve apart, clean it, replace the seat, and adjust to the proper setting. The noise is like taking an inflated balloon and pulling the sides of the opening and letting the air out. In essence that is exactly what is happening, high-pressure water is slipping by the seat and make the noise. Some times you can fix it as simply as rotating the adjustment a couple of turns then adjust back to where it was and magically it stops."
and wondered whether its applicable. If youre reading Chris, would such an action by me void warranty on the unit?
My pressure guage shows that Im at 9.1bar at the group.
