The toilet A dual flush cistern uses 3 litres for a half flush and 6 litres for a full flush. A single flush cistern uses 9 to 11 litres per flush.
choosing a water-saving, low-flush or dual-flush version when buying a new toilet - low flush toilets use six litres of water per flush compared to nine or more litres for other toilets. fitting a variable flushing device to existing higher flush toilets - this will give you a choice of flush volumes to help save water.
Are You Using Water-Saving Showerheads? Older, regular showerheads typically use between 15-20 litres of water per minute. A 10-minute shower would average between 150-200 litres per day, 1,050-1,400 litres per week, and 5,475-7,300 litres per year.
A full bath uses up to 80 litres of water whereas a five minute power shower uses about 75 litres. So, provided you don't take too long under the shower, water can still be saved. Remember to turn off the tap while you are actually brushing your teeth. A running tap uses 6 litres of water per minute.
For example a full flush toilet uses about 11 litres per flush compared to a dual flush toilet which can reduce each full flush to 4.5 litres and each half flush to 3 litres.
Not flushing saves nine gallons of water. Most people pee 6 or 7 times a day, so if you flushed every time and each flush used 9 gallons, that could mean using around 60 gallons of water every day just to flush.
Toilet Water Saving Tips
Toilets made from the early 1980s to 1992 typically used 3.5 gallons per flush (13.2 liters) or more. Toilets made prior to 1980 typically used 5.0 to 7.0 or high gallons per flush (18.9 lpf to 26.5 lpf). The oldest toilets can use more than 8 gallons per flush (30 lpf).
The average shower duration is approximately 7 minutes and the average shower volume is approximately 55 litres. In households with a high-flow shower head the average water consumption per shower is 64.2 litres. This compares with 47.7 litres per shower for households with a low-flow shower head.
The shower
A water-efficient showerhead uses approximately 9 litres per minute. An older style showerhead uses approximately 19 litres per minute - that's 10 litres more!
If you have a low-flow showerhead installed, you can expect to use about two gallons of water per minute, equalling 20 gallons throughout a 10-minute shower. With a standard showerhead, around half a gallon more water will emerge each minute, so a 10-minute shower would use somewhere close to 25 gallons.
A 12 minute shower with a flow rate of 12 litres per minute heated by electricity from 10°C will normally cost more than $1.50 in an Australian city location. Shower Timer can halve this cost.
If your home water outlets (i.e. taps and showers) can deliver over 15 litres of water per minute, this is considered good water pressure. Between 10 and 15 litres of water per minute is acceptable. Anything below this is considered poor.
If the flow rate is less than 10 litres per minute, you have low water pressure. A flow rate between 10 and 15 litres per minute is considered acceptable but can be improved. A flow rate that is above 15 litres per minute will be regarded as good.
People should still flush their toilets at least once a day. "Things like to grow in urine and after a while the chlorine will inactivate in the toilet bowl water. It will being to bubble away and things will begin to grow. The odor will increase so it can get disgusting, smell bad and stain your toilet," he said.
Since the average person flushes five times a day, the gallons can really add up. Put a plastic bottle filled with water in your toilet tank to reduce the amount of water used per flush (if you can't replace your higher volume toilet).
Put a plastic water bottle in toilet tank.
If you take a plastic bottle, put a few pebbles or rocks in it, fill it with water, and then place it in the back of your toilet, you can save up to 10 gallons of water per day.
Four-minute shower timer
Shortening the time that you spend in the shower will reduce the volume of water that goes down the drain, as well as saving you money on the energy used to heat the water.
A typical showerhead uses about 15 litres per minute (LPM). The average shower also lasts for around 7 minutes, meaning that the amount of water is 105 litres. A standard bathtub holds 30-50 gallons which equal 675 to 1250 L of water.
An approximate calculation shows that we use between 8 and 15 litres of water per minute when showering. So,on average, for a five minute shower, we would use about 57.5 litres.
Spend less time in the shower. This seems obvious, but on average, every minute of shower time equates to 2 gallons of water, and the shower of an average American lasts 8 minutes. If you shower daily, cutting back your shower time by just a minute could save sixty gallons of water per month.
An older toilet uses 7 gallons per flush, a newer one could be as low as 1.6 gallons per flush.
FACT: WaterSense labeled toilets get the job done. Many tend to associate lower flow with lower flushing power. Not true. New technology and design advancements, such as pressure-assisted flushers and modifications to bowl contours allow high-efficiency toilets to flush better than first-generation low-flow toilets.
Too much water in the toilet tank can happen when the toilet fill valve is not properly set. A level fill valve controls how much water goes down the opening and into the toilet bowl. It also sets how much water stays in the tank. An improperly set valve forces water levels to increase beyond the recommended level.
