At a certain temperature all the soaps would freeze. I mean, not become solid like water to ice, but they would become thicker and gel-like and they wouldn’t pour. At 29 degrees i had to unscrew the cap to the laundry detergent because it would just barely trickle at all from the dispenser. At 29 degrees, with 4 minutes of hot water in the tank, i had to unscrew the cap and get the shampoo in my hand ahead of time and then take a military-style shower where i turned the water off to soap up and turned it back on to rinse. Below 32 degrees none of my pumps worked to dispense the products they were designed to.
