self serve bays

[bridgewater car wash]

hi

I have a self serve bay problem. i have 3 self serve bays and the middle bay is only getting to around 700psi and i cant increase it. sometimes the pressure gauge goes all over the place and then trips out, and to me it sounds like its starving of water? any one had similar issues?
cheers

Going to need more info. What type of pump and regulator? Pictures help a lot. Could be water starving, bad regulator, bad valves, and more

hi Keno

sorry forgot to say it was a mark VII aqua spray.

all good now. cheers
