Toilet Water Usage and Water Saving Options

toilet flushThere are many things in your home that use water and it could be argued that your toilet is one of the biggest guzzlers you have, especially if it’s old. If you are still using a toilet that is as old as your house (as mine was), it might surprise you to know that every-time you flush it you’re using anything from 3 to 5 gallons of water!

My home consists of two adults and two children (both of who are at the age where flushing the toilet is a source of amusement). My wife happened to mention some-time ago that our water bills were really high and she couldn’t understand why.

Now, this is where I have to confess I became a little red faced. Considering I sell bathrooms and all the fixtures that go in them (including toilets) you would think the penny would have dropped! Eventually, of course it did, and I now have new toilets in my home that don’t use anywhere near the amount of water as the previous models.


What you should know is the EPA in America has brought in certain requirements to try and help reduce the amount of water we use, and toilets have come under close scrutiny. Requirements do differ from State to State however you don’t need to worry too much when you’re looking for a new toilet because there is something called WaterSense.

Any toilet that carries this label has been deemed as a High Efficiency Toilet or HET by the EPA. Anywhere you see this label, you can have peace of mind that not only will your water bills be reduced you’ll be doing your bit for the planet as well.

How Much Water a Toilet Uses

This depends on the type of model you opt for, but most modern toilets don’t use anymore than 1.6 gallons of water per flush which is a far cry from models that were built up to the 1980’s.

Types of Toilet to Look Out For
Aside from HET toilets, look out for these.

  • Ultra Low Flush Toilets
    Many manufacturers use this technology and none of them will use more than 1.6 gallons per flush, most even less than that.
  • Dual Flush Toilets
    Dual flush toilets give you the option to use either a light or heavy flush. On light, some models use a mere 1 gallon of water, and on heavy it can be up to 1.6.

What You Can Do to Help
Of course, there are a couple of things you can do to help conserve the amount of water your toilet uses.

  • Keep flushing to a minimum where you can.
    For example, if you have your own bathroom and it doesn’t undergo any “heavy” use throughout the night, consider saving the flush until the morning.
  • Make sure your toilet doesn’t have any leaks.
    Not only does this waste water, you could end up with damage being caused to your bathroom, and in the most extreme cases other areas of your home.

I know using a toilet is an absolute necessity and I also believe that all the toilet manufacturers I have reviewed on our website are doing their best to constantly improve the way water is used. However, until we reach a point in technology where residential toilets don’t use any water (a long time coming I think), it’s worth thinking about water conservation. Not just for your wallet, but for the environment as well.
