Making a few simple changes to your toilet flushing habits can make a big impact on water conservation. According to the EPA, toilets account for about 30% of indoor water usage in the US.
Using a low-flow toilet is a great place to start. These toilets use significantly less water per flush than traditional toilets, with some models using as little as 1.28 gallons per flush.
To get the most out of your low-flow toilet, try using a dual-flush mechanism. This allows you to choose between a full 1.6 gallon flush for solid waste and a 0.8 gallon flush for liquid waste.

Fixing Existing Toilets
Replacing a worn-out flapper valve can make a big difference in water conservation. This simple repair can be done by most homeowners, and it's a great place to start.
Inspect your flapper for signs of wear and tear, and if it looks worn or broken, you'll need to get a replacement. Measure how long the flapper valve chain is when extended, and make note of the make and model of your toilet to ensure you get the right one.

Replacing the flapper valve is a relatively easy process, and once you've got the new valve, simply slide it onto the overflow tube, seat it properly, and attach the chain. This will help your toilet flush more efficiently and waste less water.
If your toilet is noisy when filling or takes a long time to fill, it may be due to a dirty or damaged filler valve. A quick trip to the hardware store and some DIY work can usually fix the problem.

Replace Flapper Valve
Replacing the flapper valve is a simple toilet repair that can be done by most homeowners. A worn or broken flapper valve can cause a newer toilet to waste water, so it's worth checking.
Inspect your flapper for signs of wear and tear. If it looks worn or broken, it's time to replace it. The flapper is a thin rubber or plastic valve attached to a chain that pulls it up to open and allow water to enter the bowl.
Measure how long the flapper valve chain is when extended and make note of the make and model of your toilet. This will help you find the correct replacement at the hardware store.
Slide the new valve onto the overflow tube, seat it properly, and attach the chain. This is a straightforward process that requires minimal tools and expertise.

Replace Filler Valve
Replacing the filler valve is a relatively simple DIY task that can make a big difference in the efficiency of your toilet. It's a common problem that can cause your toilet to be noisy when filling or take a long time to fill.
The filler valve is responsible for allowing water into the toilet after it's been flushed, and if it becomes dirty or damaged, it won't function properly. This can lead to wasted water going into the overflow tube.
If you notice your toilet is experiencing these issues, a quick trip to the hardware store and some DIY work can usually fix the problem. However, if your toilet still doesn't fill properly, it's a good idea to hire a professional plumber to take a look.
Here are some common symptoms of a faulty filler valve:
- Noisy toilet when filling
- Long fill times
- Wasted water going into the overflow tube
If you're experiencing any of these issues, replacing the filler valve may be the solution you need to fix your toilet's efficiency and save water.
Problem Addressed
The toilet has remained largely unchanged since the late 1800s. According to Propelair, UK toilets use an average of 6 – 9 litres per flush.
This is a staggering amount of water, especially when you consider that toilets account for up to 70-85% of commercial water use in buildings. As water becomes increasingly valuable and costly, organizations can cut their carbon footprint and water costs by switching to a more resource-efficient toilet.
Older toilet flush valves can consume up to 14 liters of water per flush, and even one person uses a lot of water. This is especially true for families, where the toilet cistern is flushed four times a day per person, resulting in 160 liters of water used per day.
Here's a breakdown of the costs associated with flushing a toilet:
- 160 liters of water used per day, which costs around EUR 0.68 net per day
- This translates to EUR 248.20 per year
- The cost of wastewater is an additional EUR 2.00 net per cubic meter, bringing the total cost to EUR 3.80 net per cubic meter
These costs are not only financial but also environmental, as precious drinking water is wasted with every flush.
Upgrading to Efficient Toilets
Upgrading to efficient toilets can make a significant difference in water conservation.
A dual-flush toilet can save up to 67% of water compared to some older models. This is a great option if you're looking to upgrade your current toilet.
You don't have to replace your entire toilet to save water, though. A dual-flush toilet conversion kit can be a game-changer, allowing you to choose between smaller and bigger flushes and saving you 40% or more water than conventional toilets.
Using a modern flushing tank with low water consumption is another option to consider. These tanks can save a lot of water, especially if you use them with a timely and efficient water supply.
For example, a tank that consumes only three to six liters per rinse can make a big difference. If your family flushes 16 times a day at five liters per keystroke, you can save up to 80 liters of water per day.

This may not seem like a lot, but it adds up over time. In fact, if your family pays around 88 EUR per year for their toilet flushing water consumption, you could save around 100 EUR per year by making this change.
It's also important to clean and descale your water tank regularly to keep it working efficiently. This will not only save you money but also help minimize the risk of leaks and wasted water.
If you notice that your toilet is noisy when filling or takes a long time to fill, it may be due to a faulty filler valve. Replacing this valve can solve the problem and save you water in the long run.

Understanding Water Usage
Water usage is a significant concern, with the average American using around 80-100 gallons of water per day. This includes water used for drinking, cooking, and personal hygiene.
A typical toilet flush can use up to 3.5 gallons of water per flush, which can add up quickly. In fact, the EPA estimates that toilets account for around 30% of indoor water usage in the US.
Conserving water is crucial, especially in areas with limited water resources. By taking simple steps like fixing leaks and installing low-flow fixtures, we can make a big impact.

Invest in Low-Flow
Investing in a low-flow toilet can make a big impact on your water usage. Low-flow toilets use gravity or pressure to push waste into the pipes, giving them an edge over older models.
You can save as much as six to seven gallons on every flush compared to older toilet models. This is a significant reduction in water waste.
Low-flow toilets must use 1.6 gallons of water or less per flush to qualify, according to the EPA. Some toilets even use as little as 1.28 gallons per flush.
Older toilets, on the other hand, use between 3.5 and 7 gallons per flush. This is a lot of water, and making the switch to a low-flow toilet can make a big difference.

Flush Water Usage
Older toilets can be real water guzzlers, using up to 14 liters of water per flush.
This can add up quickly, especially in households with multiple people. In Germany, a family of four people uses their toilet 16 times a day, consuming 160 liters of water daily.
The cost of this water usage can be significant, with a price tag of around EUR 0.68 net per day, or EUR 248.20 per year.
Low-flow toilets, on the other hand, can save up to six to seven gallons of water per flush compared to older models. They use gravity or pressure to push waste into the pipes, making them a more water-efficient option.
To qualify as a low-flow toilet, it must use 1.6 gallons of water or less per flush, according to the EPA. Some toilets even use as little as 1.28 gallons per flush.
