The Pros & Cons of Installing a Low-Flow Toilet

Low-Flow Toilets

Low-flow toilets: we’ve all heard of them, but what do they do exactly? Most people’s two main assumptions about low-flow toilets are that a) they are good for the environment and b) they make it harder to flush. But the truth about this kind of toilet is a little more complicated than that. Keep reading to learn the pros and cons of installing a low-flow toilet from our experienced plumbers at Carter Quality Plumbing.

The Pros of Installing a Low-Flow Toilet

Water Savings

It must be said right off the bat that the biggest advantage of low-flow toilets is how much water they save—in small increments and over time. Gravity and pressure-assisted models both reduce the amount of water required to get rid of waste, which is good for you and for the planet. In fact, the EPA has estimated that switching to a low-flow toilet can cut down the average homeowner’s water bill by as much as $110.


While the initial estimate of installing a low-flow toilet may be significant, these units tend to be a great investment, as they can last up to 30 years and may actually increase your property value.

Rebates May Be Available

Low-flow toilets are also a great choice for new construction projects. Some cities and states even offer rebates for replacing your current toilet with a low-flow model.

The Cons of Installing a Low-Flow Toilet

May Require More Than One Flush

It is true that because of their water-saving power, low-flow toilets do not always flush away waste as effectively as traditional models. They have gotten more effective with recent innovations, but you may still need to flush a low-toilet several times to completely get the job done (though the cumulative amount of water used in these flushes will obviously be less than what you would be using in a standard model.)

Installation Limitations

It can also be difficult to install a low-flow toilet with your existing plumbing system, depending on how old your home is. Because low-flow toilets function by using pressure and gravity, the pipes they connect to have to be positioned in a very specific way. With older homes, you may need to replace more of your plumbing system to properly upgrade to a low-flow unit.

Bottom line: if your house was built sometime in the last few decades, you probably won’t have a problem putting in a low-flow toilet. However, the older your home is, the more expensive it is likely to be to switch to any low-flow fixtures.
