Dual-Flush Toilets: Another Great Green Plumbing Innovation

Wednesday, February 2nd, 2011

If you’ve traveled to Europe or Australia, you’ve probably seen toilets with two buttons instead of a single flush handle. Pressing one button flushes the toilet lightly to remove liquid waste, and pressing the other produces a higher-volume flush to remove solid waste.

Originally designed for drought-prone Australia, these water-saving toilets are becoming increasingly popular in North America as well.

Standard 1.6-gallon toilets are a great improvement over older toilets, which used 3 or even more gallons per flush. But dual-flush toilets are even more water-efficient. A “full flush” uses 1.53 gallons per flush, and a “half flush” uses only 1.02 gallons per flush. The result is a reduction of up to 68% in water usage over a conventional toilet (and even more if your conventional toilet is old and leaky).

Of course the savings vary from person to person, but if you use the toilet an average of 5 times a day, you’ll save close to 600 gallons of water every year. For a family of four, that works out to a total savings of 2400 gallons annually. And, since toilet usage typically accounts for roughly a quarter of your water bill, you can end up with a monthly savings of close to 17%.

Another benefit of dual-flush toilets is that most models have a larger trapway for removing waste than conventional toilets – which reduces the likelihood of a clog.

Finally, dual-flush toilets look great. They are sleek, modern, and European-looking, and they perfectly complement a high-end bathroom.

WaterSense Labels

Friday, January 28th, 2011

Many people know about the EPA’s EnergyStar certification, which is a third-party certification system that verifies manufacturers’ claims about the energy efficiency of home appliances. The EnergyStar label has helped hundreds of thousands of consumers choose high-efficiency, cost-effective appliances for their homes.

The EPA has also developed a certification for plumbing fixtures, called WaterSense. WaterSense labels can be found on a variety of products, including:

  • Bathroom sink faucets and accessories
  • Showerheads
  • Toilets

While there are specific guidelines for each category of plumbing fixture, in general, the WaterSense label indicates that the product is at least 20% more efficient than conventional products in its category, without sacrificing performance or comfort.

The goal of the WaterSense guidelines is to make a real difference in the amount of water consumed in the U.S. – and the numbers bear this out. Let’s take a look at what would happen if every household in the US installed WaterSense products in their bathrooms.

If every household in the U.S. installed WaterSense bathroom sink faucets, it would save 60 billion gallons of water and $600 million in water heating costs. If every U.S. household put in WaterSense showerheads, the US would use 250 fewer billion gallons of water annually and save $2.5 billion in water heating costs. And if every household in the US upgraded to a new, efficient WaterSense toilet, it would save 640 billion gallons of water a year.

More realistically, even if only 1 in 10 U.S. households upgraded to WaterSense products, we would save about 74 billion gallons of water a year and $1.5 billion on our water heating bills.

Like EPA EnergyStar products, WaterSense products can be found at most plumbing retailers.

The WaterSense label can also be applied to entire homes. Homes that have the WaterSense label have:

  • Efficient hot water systems that deliver hot water quickly to minimize waste and waiting
  • WaterSense plumbing fixtures
  • EnergyStar dishwashers and clothes washers
  • Regionally appropriate outdoor landscaping that requires minimal maintenance and watering

In addition, landscaping professionals can apply for WaterSense certification to show that they have training in water-efficient irrigation system design, installation, maintenance, and auditing.

Green Your Plumbing

Monday, January 24th, 2011

These days, “green plumbing” is getting increasing attention, especially in dry areas like the southwestern US.

“Green plumbing” helps the environment by doing one or more of the following:

  • Saving water
  • Saving energy
  • Using environmentally-friendly materials

There are a wide range of green plumbing products that can make a big difference in how much water and energy your home uses. They range from simple accessories that cost less than $20 to major home remodels. Here are a few of them, ranging from the simple and immediate to larger investments with a longer-term payback.

  • Low-flow showerheads and faucet accessories (often called “aerators”). Check the side of your current faucet and showerhead to see if they use more than 1.5 GPM and 2.0 GPM, respectively. If they do, you can benefit from an upgrade. Look for the EPA WaterSense label to be sure that your new showerheads and faucet accessories are water-efficient.
  • Hot water heater blankets and pipe insulation.You don’t need to insulate your hot water heater and  pipes to prevent freezing, but doing it will save money, water, and energy, and (as a bonus) you’ll enjoy hotter showers in the winter. This is a simple DIY job and the materials are extremely affordable.
  • Touch-free faucets. When you’re not actively using them, touch-free faucets shut off. According to industry estimates, the result can be a water savings of up to 70%. Touch-free faucet technology has improved greatly in recent years, and sensors are now very reliable. If you like your current faucet and want to keep it, there are also touch-free faucet conversion kits.
  • Dual-flush toilets. As the name suggests, these toilets have two different flushes: a “half-flush” for liquid waste, and a “full flush” for solids. Dual-flush toilets are standard in many European countries and are becoming increasingly popular in the U.S. because of their water-saving potential (up to 68% over conventional toilets) and sleek styling.
  • Tankless water heaters. Unlike conventional tank heaters, which use energy constantly to maintain a reserve supply of hot water, tankless heaters only use energy when hot water is needed.  Tankless water heaters are not quite “instantaneous”, as some manufacturers claim, but they provide hot water within a few seconds. Good quality heaters can provide hot water to multiple fixtures simultaneously.
  • Sprinkler system upgrades. Much of the water from spray sprinkler systems evaporates. Trickle and drip irrigation systems can improve water efficiency by delivering smaller amounts of water directly to the base of the plant. Other products, such as pressure regulating spray heads and rotors and automatic rain sensors, can also save thousands of gallons a year. Another option is to re-use laundry waste water by diverting it into the garden. This can be a DIY project or can be built directly into your plumbing. Check with your local authorities to find out if this is permitted in your area.
