Choose the Best Low Flow Toilet

Did you know if every home replaced their old toilet with a new high efficiency toilet, more than 900 billion gallons of water would be saved each year? That's enough to supply almost 10 million households, per the U.S. Environmental Protection Agency.


If the toilets in your home are from the mid-1990s or earlier, then consider installing new ones to save big on your water bills. All new models are 'low-flow' toilets ? by law they can use no more than 1.6 gallons of water per flush. Prior to 1994, most toilets on the market used at least 3.5 gallons, or about 20 gallons of water per person per day ? the most water used by any household appliance.

But while some low-flow models work well, others do not. That's because to comply with the federal regulations on toilets' water use, some manufacturers initially reduced the volume of water that discharges from the tank, without also making the necessary design adjustments. New designs have improved the performance of many models, but some still do not flush thoroughly.

Finding a low-flow, gravity-flush or pressure-assist toilet that performs well is now easier than ever, thanks to Veritec Consulting, which publishes toilet performance results several times a year in a report that has become the industry standard for rating toilets. See Half the Water, Twice the Flush in the Aug/Sept 2006 issue of Mother Earth News for Veritec's toilet performance ratings.

If you're looking for more information on upgrading toilets read Green Remodeling, a Mother Earth News Wiser Living Book. Highly recommended by the editors of Mother Earth News, 'Green Remodeling' is a comprehensive guide for green renovation solutions. For more details, see below.

    We have replaced all toilets n the last home and this one with
    1.6 gallon flush toilets. We only had a problem with one not
    flushing on the first try. We have the water setting set to low for
    each one. We also follow the "If it's yellow let it mellow if it's
    brown flush it down", theory. In addition we use the dehumidifier(
    a needed commodity in our basement) water to flush our toilets,
    wash our cars, or water plants. I have plans to make a water
    colleciton system from barrels, plans I got from a
    magazine.

    If you're not ready to replace the whole toilet yet, I found an
    adjustable flapper at my local home improvement store. You just
    adjust the flow where it only uses the bare minimum amount of water
    to make it all work.

    The One Gallon ToiletWent to the hardware store and bought 1/8
    solid tin solder wire, wrapped 10" worth around the brass vertical
    stopper wire inside the toilet. Just hold the handle down to a
    count of three or four when flushing and release. Works on most any
    toilet with a vertical drop arrangement. - submitted by Joe

    The most environmentally sound advice regards old cisterns that
    are still working, is to put a brick into the cistern to reduce the
    water volume. Oh so very cheap and you save on the landfill.

    HelloWhy not promote the Humanure no flush composting toilet? He
    has been using it for over 20 years and it works just fine. I Build
    it for less than $20. One of my friends has been using this at his
    cabin for over 3 years now (Him, his wife and kids). He will never
    bother to put in a septic system. My other friend has also been
    using this concept in his rural home for just over 2.5 years. I
    have just started to use one. Yes they work. They make the system
    work the way it was originally intended to work. Check it out.

    I have two bathrooms. My experience tells me that the 1.6 gal
    low flow toilets saving water is a great myth. Since converting to
    said toilets, instead of using the touted 1.6 gal, after two or
    three flushes, it all adds up to more like 3.2 to 4.8.

    I have a laminated sign above my toilet "If it's yellow let it
    mellow. If it's brown, flush it down." Above the toilet I have an
    article about urine's beneficial uses as a garden amendment being
    high in nitrogen and pathogen-free (unless someone has a urinary
    tract infection). When we don't have company I use a bucket and
    carry it out to a compost pile out back. I'm investigating
    composting toilets but haven't been able to commit to one model
    (although SunMar makes a hot pink one that I think looks very
    friendly and non-threatening to the squeemish. I'm not handy so I'm
    going to go with a free-standing model that doesn't require a
    basement component.

    We just this passed weekend replaced our commode in our upstairs
    bathroom. It is 1.6 gallon flush and everytime we flush it I
    smile!!! We really needed to do something. We bought a Koehler
    brand at Lowes for $225.00 and worth every penny by the way, but it
    had a description as a class V. But it will flush complete and
    quietly every time. It is amazing how much the little things in
    life can be such a blessing! Our water bill was $46.00 for the last
    time!!Cathy SimsFarragut, TN
