Hello Everyone,
I have been checking out this site for a few years now and you all have been very helpful. Been in the car wash business for almost 6 years and have learned a lot with your help. I have a 6 bay ss wash and in 1 of the bays when the spot free rinse is in use i am getting a little back flow of water (about 40psi) into my pump. I have checked or replaced check valves in the attic out by the bay and nothing seems to fix the problem. I have checked and have not found any leaks at the pump and have eliminated the weep system (down in the Tampa Bay area of Florida, don't have to worry about freeze). Any ideas of other things I might check would be greatly appreciated.
Bob
