A water-efficient toilet works by using less water per flush than traditional models, typically 3β6 liters compared to older toilets' 9β13 liters. Most water-efficient toilets have a dual flush button that allows you to choose between a small flush for liquid waste and a large flush for solid waste. This system significantly reduces your water consumption without compromising on functionality.
What is a water-efficient toilet and how does it differ from regular toilets?
A water-efficient toilet is defined as a toilet that uses a maximum of 6 liters of water per flush, while many modern models manage with only 3β4 liters. Older toilets from the 1980s and earlier can use up to 13 liters per flush, which makes a dramatic difference.
The basic technology behind the water-saving feature is based on improved flush geometry and optimized water pressure. Water-saving toilets have specially designed porcelain bowls that channel water more efficiently, larger water traps for better flow, and improved flush edges that ensure the entire bowl is cleaned with less water.
Modern water-efficient toilets also use gravity systems or pressure-assisted flushing to maximize cleaning power. This means you get the same or better performance with significantly less water consumption than older models.
How does the dual flush button on water-saving toilets work?
The dual flush button system gives you two different flush options: a small flush, which uses approximately 3 liters for liquid waste, and a large flush, which uses 4β6 liters for solid waste. The smaller button or a shorter press activates the small flush, while the larger button or a longer press activates the full flush.
The system works by regulating how much water is released from the cistern's two chambers or by controlling how long the flush valve is kept open. When you press the small button, only part of the outlet opens, while the large button activates the entire flush mechanism.
This system is more water efficient because most toilet visits only require a small flush. By using the right flush for each occasion, a family can save up to 30-40% water compared to traditional single-button flushing. The smart design allows you to easily adjust water consumption according to your needs.
What are the environmental and economic benefits of water-efficient toilets?
The environmental benefits of water-saving toilets are significant, as toilet flushing accounts for approximately 24% of total household water consumption. A family of four can save up to 15,000 liters of water per year by switching from an old toilet to a water-efficient model.
From a financial perspective, water-efficient toilets reduce both your water bill and sewage costs. The savings depend on local water rates, but many households see a reduction of SEK 200β500 per year from toilet use alone. The investment in a new water-efficient toilet often pays for itself within 3β5 years.
The long-term impact on household water consumption becomes particularly noticeable over time. Lower water consumption also reduces the burden on municipal wastewater treatment plants and contributes to sustainable water management. This is particularly important in areas with water shortages or high wastewater treatment costs.
What should you consider when using a water-efficient toilet?
For optimal use of water-efficient toilets, select the correct flush for each occasion β use a small flush for liquid waste and a large flush for solid waste. Avoid flushing unnecessarily or holding down the button longer than necessary, as this consumes extra water without improving cleaning.
Maintenance tips to preserve the water-saving function include regular cleaning of flush edges and checking that the flush mechanism is working properly. Check that the dual flush button system activates the correct amount of water β if the small flush uses too much water, adjustments may be necessary.
Avoid using the toilet as a wastebasket for sanitary pads, condoms, or other items that may cause blockages. Water-efficient toilets are designed for toilet paper and bodily fluids, and foreign objects can disrupt the optimized flush geometry and require unnecessary extra flushing.

Frequently Asked Questions
Can I install a water-efficient toilet myself, or do I need a plumber?
Although it is technically possible to install a water-efficient toilet yourself, we strongly recommend hiring a professional plumber. Installation requires proper connection of water pipes, adjustment of the flush mechanism, and ensuring tightness. Incorrect installation can lead to water leaks, poor flushing performance, or damage to floors and walls.
What happens if the small flush is not enough to clean the toilet properly?
If a small flush does not provide sufficient cleaning, this may be due to incorrect adjustment of the flush mechanism or that the toilet needs cleaning. First check that the flush edges are free of limescale and dirt. If the problem persists, the flush system may need to be adjusted by a technician to ensure optimal water pressure and flow.
How long does it take for a water-efficient toilet to pay for itself?
A water-efficient toilet usually pays for itself within 3-5 years, depending on local water rates and how big the difference is compared to your old toilet. A family that switches from an old 13-liter toilet to a 4-liter model can save $20-50 annually on water costs, which means that the investment quickly becomes profitable.
Is there a risk that water-saving toilets will clog more often than regular toilets?
Modern water-efficient toilets are designed with improved flush geometry and larger water traps, which actually reduces the risk of blockages compared to older models. The problem usually arises when users flush items that do not belong in the toilet. Follow the instructions for use and avoid flushing sanitary pads, condoms, or large amounts of toilet paper at once.
Can I upgrade my existing toilet with a dual flush button instead of buying a new one?
In some cases, existing toilets can be upgraded with new flush mechanisms that have a dual flush button function. However, this requires that the toilet cistern is compatible and that the installation is carried out correctly. Contact a plumbing technician to assess whether your toilet is suitable for upgrading or whether a complete replacement is more cost-effective.
Which brands and models of water-efficient toilets do you recommend?
We work with several well-known brands such as Gustavsberg, IfΓΆ, and Duravit, all of which offer high-quality, water-efficient toilets with dual flush systems. The choice of model depends on your bathroom, budget, and specific needs. Our technicians can provide personalized advice based on your circumstances and help you choose the most suitable solution for your home.
