So, I wanted to pay less while conserving water and energy... but how?
Well, we did it by installing a low-flow showerhead that reduces the amount of water being used. Some low-flow shower heads claim to cut water use by 50% to 70% while delivering a vigorous flow. Besides reducing water, it can also cut down on your water heating costs (electric or gas).
There are many styles and options to choose from like this one: Delta Faucet Showerhead
We didn't notice much difference in our shower, but our water bill showed us the difference and I love saving monthly on water bills.
