Results from low flow, or flow restricted, shower heads and flow restrictors will vary, but you could reduce consumption by up to 60%. It all depends on the flow rate - which is the volume of water that passes through per second, or minute.
Install Flow Restrictors
Flow restrictors belong on all bathroom and kitchen faucets. Each one can save you up to 5,000 gallons, or about $10 every year.
In applications where a large volume of water is used, such as showers and water filtration systems, a flow restrictor can save you money on your water bill each month. Flow restrictors can be applied to all bathroom and kitchen faucets, and they must be used for reverse osmosis filtration systems.
A standard 2.5 GPM shower head uses 2.5 gallons of water each minute. That's 25 gallons for a 10-minute shower. VS. A low-flow 1.8 GPM shower head uses 1.8 gallons of water each minute.
A flow restrictor will increase the pipe pressure on the upstream side of the restrictor. The increase in back pressure, coupled with the decrease in orifice size that the water can come through, results in a decrease in flow rate output (gallons per minute) but an increase in the flow speed and force.
Removing the water restrictor from your showerhead can also improve water pressure. Removal might also clear out mineral build-up around the restrictor. It's fine for you to remove one if you live in an apartment unless otherwise stated. Note that your water bill may increase after removal.
After all, it needs certain amount of water to remove the soap, that is physic. Studies have shown that 1.8 gpm is the minimum flow rate to have a good enjoyable rinsing, so the common 1.75 gpm models, is somewhat good enough for a decent shower. To save water further and still have a full enjoyable rinsing experience.
If you're looking for the most pressure, go for the 2.5 GPM Flow Rate, unless you are restricted because you reside in California, Colorado or New York. Again, this has been the Maximum Flow Rate since 1992.
High Pressure Shower Heads Can Save Water
If you generally get low pressure water at home, you'll probably notice that your water bill is on the higher end. However, eco-friendly shower heads that also have high water pressure ensure that you save water even as you enjoy your spa-like shower.
The average bath uses about 80 litres of water. Over the course of four minutes a normal shower head produces about 36 litres.
Saving Water Saves Money
With a 2.5 gpm showerhead, you'll soak up nearly 440 gallons of water in one month from shower use alone. With a low-flow showerhead, 175 minutes of showering uses just 262 gallons of water. Which means you save about 60 percent every month.
The average family could save 2,700 gallons per year by installing WaterSense labeled showerheads. Since these water savings will reduce demands on water heaters, they will also save energy. In fact, the average family could save more than 330 kilowatt hours of electricity annually, enough to power a house for 11 days.
Shower gallons per minute
The average American shower uses 17.2 gallons (65.1 liters) and lasts for 8.2 minutes at average flow rate of 2.1 gallons per minute (gpm) (7.9 lpm).
That's why it pays to invest in a quality low flow eco shower head that not only saves water but does it without making your shower feel like a drudge and no fun at all. A well-manufactured shower head from a trusted brand will reduce water consumption by up to 60%, which is a big saving year on year.
A low-flow showerhead, on the other hand, can help you conserve water and energy, helping the planet and saving you money on utility bills. Showers are responsible for, on average, 17% of household water use and 50% of hot water use.
A high pressure shower head sprays out water with more force, maximizing the water flow, giving you a more complete cleaning experience, but using more water and energy. A high pressure shower head provides a spa experience with natural massage therapy and different spray patterns that is beneficial to your wellbeing.
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.
Efficient shower heads use at least 1.5gpm. Taking the same amount of time in the shower uses only 15 gallons of water. The water savings amount up to 65 gallons of water!
If your water pressure seems low, the first step should be to test how much pressure you're actually getting from the shower head. A typical home's water pressure should be somewhere between 45 to 55 psi (pounds per square inch).
Also known as “flow rate”, GPM is a measure of how many gallons of water flow out of your shower head each minute. Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute.
Areas indicating a maximum flow rate of 4.0 gallons per minute or more are generally satisfactory for running 2 showers at a time with standard showerheads.
Two big reasons: To help lower utility bills -- and to conserve water. According to the EPA, the average family could save 2,700 gallons per year by installing WaterSense labeled showerheads. Since these water savings will reduce demands on water heaters, they will also save energy.
