Wax problem


When you get to your car wash and you see chemical seeping out of the building it is always bad.


I swapped to this foot valve yesterday because I am going to switch tanks and apparently it does not work.  The only thing I can think of is the foot valve started a suction and kept draining the tank.  This over flowed the chemical tank and cycled on then suction all the water out again and again.  Making a huge mess.  I cut a hole in the outlet of the hydrominder hose.  Which should prevent this from happening again.
