Do Low flow shower heads save money?
Do Low flow shower heads save money? Low flow showerheads reduce both water and energy usage, since reducing the amount of water used by the shower will also reduce the amount of energy used to heat it. In doing so, low flow showerheads also reduce the amount of money spent on utilities. Are Low flow […]
