A lot of people are finally starting to realize the impact humans have on our clean water supply and have become more conscientious about how they use water and how much water they use. One question we see frequently asked online is – can I put a brick in my toilet tank to help conserve water?
This is a valid question for anyone wanting to save water, as the toilet uses nearly 1/3 of our indoor water consumption, and technically, yes you could…but we really don’t like to recommend that. While we here at PlumbingSupply.com truly care about water conservation and try to do our part to save water and help others to save water, putting a brick in your toilet isn’t the way to do it.
All toilets manufactured after the early 90’s use only 1.6 gallons per flush (gpf) or less, with many of the newest models using 1.28gpf. Older toilets do use significantly more water, with most being 3.5gpf, but some using up to 6gpf – that’s a lot of clean water being flushed – but it’s important to understand that these toilets were specifically designed to use that much water and they typically won’t flush properly with less. And yes, we completely understand that your toilet LOOKS just like the low flow toilets…from the outside…and that this can be confusing for many people. Trust us, the inner workings can be significantly different. An extra bend or an extra inch of height in the toilet trap can mean a lot when you’re moving waste with only water and gravity.
For sanitary reasons, you really want all that waste to be disposed of properly and not stuck in your toilet trap or your home’s sewage line. So, it’s important that the correct amount of water is used to help that waste move along the sewage lines and help prevent clogging – which means you really shouldn’t use a brick, or anything else for that matter, to reduce the amount of water in your tank.
We’re aware that there are plenty of articles out there telling you otherwise – that it’s perfectly fine to displace the water in your toilet tank to help conserve and that your toilet will flush either way. Which is true, in most cases. Your toilet WILL flush, but it won’t be doing so effectively. And that opens up the potential for serious problems in your home or community sewage system down the road.
If you’re concerned about water conservation and have an older toilet with a higher flush rate, we strongly recommend you replace the toilet with a newer, water-saving model. That is the most effective method of saving water when it comes to toilets. Also, regardless of whether your toilet is new or old, making sure you check periodically for leaks and repair them quickly can also save significant amounts of water.
However, IF you choose not to replace your older toilet and you choose to use the “brick method”, it is a better idea to take a plastic water bottle and fill it up with sand or small pebbles and place that in the tank instead of a brick. Even a brick wrapped in plastic can break down in the tank, especially if you get a hole or loose seal in the plastic wrap.
