Do you know that there is an adjustment in the water volume of the toilet flush? I learned that when our toilet flush stopped working. The plumber replaced with a new one and asked me how much water I would like for the flush. He taught me how to adjust the volume of water. Isn’t it a big savings even if you lessened the water in the toilet flush by just one glass? Especially when there are many who are using the toilet, that one glass saved would mean a lot.
