Soap in spot free rinse?

[Mark]

I have a three bay ss with one IBA. I'm getting soap in the spot free rinse in bay three when bay two is on high pressure soap. Also when using spot free rinse in bay one or three, there is also spot free running in the opposite bay, but not in bay two. The IBA doesn't effect any of this. Any ideas were to look? Thanks!

Your check valve is stuck on bay 2 at the "t" where the spotfree ties to main pressure hose.

Agree with ratfink, you have at least one open check valve in your system.
