I am new to the forum and looking for advice on sealing my toilets while away from my homes for 6 months. I have two homes and the temperature is controlled to prevent freezing (above 55 F) in one home while we are away in winter, but our winter home can reach temperatures above 100 F when we are away in the summer. The water has evaporated from the bowls and grown algae in the tank upon our return. I have tried a water balloon, but it leaks after one month and fills the bowl and the seal is broken. I have tried sealing the tank and bowl with cling wrap without complete success. I have read about adding mineral oil in the bowl to reduce evaporation, but I am not sure it will last 6 months. I am curious about an inflatable test plug. Can this be inserted into the bowl and into a round straight portion of the toilet that would create a seal? Any thoughts or ideas would be appreciated.
Thanks
