tanks filling up with water

[Jimmy Buffett]

I have a J Coleman pump bench. Everything but detergent and wax is now fed directly from the soap bucket instead of the tanks in the pump bench. Today most of those sections on the bench are full of wate,r I guess. There was small amounts of concentrate left in the bench but now many of them are full of red liquid. Oddly enough functions in the bay look just fine. What do I need to be looking for here? A bad check valve? but where?
Thanks

Sounds like you some foot valves bad.

Jimmy,
I am not sure about what you are explaining. If something is coming into a concentrate container then some check valve is leaking. Follow the hoses from containers to the chemical that is red. The only thing that is red in our car wash is polish wax but it is not connected to any of the functions that go through the trigger gun.

I have a guy coming by tomorrow to do some other stuff. I'm just going to have him deal with this while I'm hemoraging money anyway. I think it will be fairly simple once he figures out which valve it is.
Thanks

It does sound like you have a foot valve or check valve in one of the concentrate tanks that has gone bad. The easiest solution is to cut or drill a hole in each Hydrominder drop-tube (It must be below the disk inside the tube). That will prevent it from siphoning the mixed chemical back to the tank if the foot valve fails.
