Shower use and/or bath use accounts for one fifth (1/5) of an individual's total water use. Most older showerheads use anywhere from 15 to 30 litres of water per minute or about 6 GPM. Check the flow rate of your showerhead. A showerhead with a flow rate of less than 10 litres per minute (approximately 2.0~2.5 GPM) is considered to be water efficient and meets the requirements of the plumbing code of Ontario. When your tenants are using less water in the shower or bath, not only do you save money on your water bill but you also save on your hydro or gas bill

Low Flow but High Pressure

Don't confuse a high pressure/low-flow showerhead with a flow restrictor. A low-flow showerhead is designed to deliver fewer gallons of water per minute but with the same pressure as a traditional showerhead. Your showers will be as good as those with your current showerhead. A flow restrictor, on the other hand, simply cuts back the flow without compensating for pressure. Quite often, inserting a flow restrictor cuts down on water use but results in an unsatisfactory shower.
