While a Trelino can be used in any weather, there are some tips we recommend for differing temperatures. In very hot weather, toilets should be emptied more often as they can become more prone to smells. In very cold temperatures, our toilets should be given more opportunities to air out. The difference in temperatures between the contents of the toilet and the colder weather can cause condensation and slow down the composting process. To help air out your toilet, you can install a vent attachment or take it outside to breathe with the lid off periodically.
