Soap in warm water Rinse Tank?

[MDrost1]

Folks,

Here is my confounding situation of the day. My warm water rinse tank which mixes with soap and wax for my HP soap and wax has what seems to be soap in it today. It turned out to be a very busy day.

We put this new tank in 4 months ago. All has been fine. It is a different style where the top cover prevents any condensation from coming out. The lip is on the inside of the tank. Our old one allowed water to condense out the side of the tank. Not pretty, but oh well.

The water level is not overflowing. Operating normal with the exception of the polluted tank. Cold water rinse seems fine. None of the check valves appear to be causing pulsations.

Needless to say, I am confused. Has anyone ever seen condensing from the soap tank dribble into the rinse tank and polluting it a little bit?

Any thoughts as to what this might be?

Thanks!!!!!

You've likely got one or more leaking weep system check valves.
High pressure soap and wax is pushing by the CV and you're seeing it in the rinse tank.

yep, take the weep line off of the check valves and then flip each bay on HP soap/rinse and see which one is leaking through.

It's probably not high-pressure soap going into the tank because when that it running it can only go out to the bay or (usually) out another bay through the weep. You could have a check valve at the boom on one bay letting tire cleaner or presoak all the way back through the hose, through the pump and into the tank.

Next time you see it, taste the foam and make sure it isn't salt. I've seen a softener malfunction and put brine into the lines, and it foams like soap in the tank. (They use salt foam to put a head on fake beer in TV shows)
