If you just saw a tank that said "Rinse" and "Soap" on the front, you may be confused. Many systems only draw from the hot water for soap and wax, and the actual rinse selection opens a cold water solenoid. The soap itself can be cold because only a very tiny fraction of the high pressure soap in the bay is drawn from the soap tank, so what you saw as "cold soap" and "hot rinse" is irrelevant to what the customer actually gets.Joe said:
I still think you missed the true function of the individual tanks. The soap and wax compartments are not the sole supply to the pumps when those functions are selected. Look under the tanks and you'll see very small hoses or tubing coming from the soap and wax tanks, and large hoses from the "Rinse" tank. The soap and wax mix with the hot water at the pump, with only a tiny amount of the soap or wax mixing with hot water and not enough to significantly affect the temperature. "The guy" you mentioned may not know how it works either.Joe said:I just wondered if I was missing something that I should know.
The typical setup is to have the rinse selection feed cold water to the pump via a solenoid. Unless the bays rinse with hot water, the tanks are not used at all during rinse.Joe said:They are using the water from the rinse tank to feed the soap and wax low pressure systems as well as the rinse.
