How Tankless Toilets Work

The first thing to know about the tankless setup is that they don’t have a tank! That’s right, instead of holding water in a tank like traditional toilets, tankless toilets get their water from the main water line. Most homes lack enough water pressure. Therefore, a tank is required.

Tankless toilets are a great alternative to the traditional model because they don’t require you to refill their tanks with water each time. Instead, an electric pump generates enough pressure and uses siphon action that allows waste from your bowl to flow into the drainage system without overflowing.

Gravity flush toilets are another name for tank toilets. The primary reason is that the toilet tank is positioned directly above the tank, and gravity comes into effect during flushing. There are no electric components involved in a tankless toilet, so they do not require electricity to operate.

Water is supplied through a pipe via the shut-off valve in the tank, resulting in always having a full tank of water. Traditional models used as much as 3.5 gallons per flush, while newer types have more than halved that by only utilizing 1.6 or 1.28 gallons per flush. 

A flushometer is a device used to empty tankless toilets. Every time you press the flushometer, a measured quantity of water is released into the toilet. Some domestic tankless toilets are referred to as smart because they feature automated flushing systems, whereas others rely on wireless remote controls.

There are some installations that can combine both functions. Tankless toilets have fewer leaks resulting in fewer call-outs, and are perfect for small spaces due to their compact nature.

Tankless Toilet vs. Pressure Assisted Toilet

Pressure-assisted toilets look almost identical to tank toilets, even though they do not employ the same functionality for the flush. They work by having a second tank within the primary tank, called a pressure vessel.

The water is fed into the pressure vessel through a tube; using the trapped air inside the vessel, it compresses the water keeping it under pressure within the tank.

Flushing the toilet releases the pressurized water with considerable force, making this louder than gravity toilets.

People who want to install rear discharge toilets, also known as rear outlet toilets, will benefit from pressure-assisted toilets. In contrast to the conventional toilet, waste exits from the back. In essence, the rear outlet toilet has a much shorter trap resulting in a weaker siphon action. The pressure-assisted system provides the extra power needed.

Tankless Toilet vs. Wall Hung Toilet

Wall-hung toilets, often also referred to as wall-mounted toilets, are another sort of toilet that often get confused with tankless toilets. They resemble tankless toilets but have a tank instead.

Unlike other toilets, wall-hung toilets are not placed on the floor. The tanks of wall-hung toilets are placed behind the bathroom wall.

A wall-mounted toilet uses a carrier frame to secure the tank on the wall. The toilet bowl is also attached to the carrier frame via lengthy bolts.

Usually, another wall is built to conceal the toilet tank, with the flush buttons located in a small gap in a convenient position. If you need to work on the toilet in the future, this gap provides the perfect entry point.

Tankless toilets, on the other hand, unlike wall-hung toilets, sit on the floor and do not require frames to attach anything or another wall for that matter.

Pros Of A Tankless Toilet

A small bathroom may be equipped with a tankless toilet without it feeling cramped. A tankless toilet, on the other hand, will make a little space seem larger.

Tank toilets are generally grander than tankless toilets due to the tank, which means they’re also longer. 

Rapid Flushing

Tankless toilets are always ready for use as they do not require to be refilled. They are ideal for a bathroom with many users since they don’t need to be refilled. Tank toilets require the tank to be refilled between flushes, and if the toilet did not properly flush the first time, then you will have to flush again, which means you will need to wait for the tank to fill up for a second time.

Reduce Water Bills

Tankless toilets allow a precise amount of water in every flush, reducing water wastage. They are not only more environmentally friendly, but they will also reduce your water bills as they do not generally leak.

Easy To Maintain

Tankless toilets don’t have as many moving components, and users do not have to worry about the wear and tear of the tank where most issues arise. Durable, low maintenance and longevity are just some of the benefits of installing a tankless toilet.

Easy To Clean

A tankless toilet is far less complex than a tank toilet, with little to no chance of mold or mildew building up. Tankless toilet maintenance is thus very simple and quick. Dirt has no place to hide in their bowls since they are generally completely skirted.

Cons Of A Tankless Toilet

Electricity is required for tankless toilets. If you tend to have electricity issues in your neighborhood, the tankless toilet will cause you more problems than you bargained for. This can, however, be solved by using a bucket of water or a generator. It is worth noting that the latter can be a noisy and expensive solution.

Difficult To Repair

Tankless Toilet parts tend to be expensive compared to tank toilets and are not as readily available. It is worth mentioning that a professional is recommended to deal with any problems due to the complicated nature of the setup of a tankless toilet.

High Cost

Tankless toilets, with their numerous features, cost a lot more than tank toilets. If you opt to install a tankless toilet without the bidet functions, it will be considerably cheaper.

Loud Flush

Tankless toilets use a lot of water pressure to clean the bowel. As a consequence, they are considerably louder than a tank toilet. This can especially pose a problem if you have young ones who get woken up easily or if you need to flush the toilet late at night.

History Of The Tankless Toilet

John Harington was an English poet in the 1600s who invented the first flushing toilet. It was named the Harington tub; however, even today, it is referred to as a ‘John’ in the UK.

The aforementioned WC was typical of modern flush toilets using water from a tank to cleanse waste from the bowl down the drain. However, the problem was that hardly anybody had these toilets or any plumbing to mention.

It was, however, hailed a resounding success. Harington even created a variant for Queen Elizabeth.

In 1906 the Sloan Valve Company created the first flush toilet controlled via a valve. It’s unclear when they were used first; however, it is known that Thomas Crapper designed and patented a flushing system for them in 1885.

The valve essentially regulated the flow and quantity of water, allowing sufficient water to cleanse the toilet bowl. Sloan’s original design was modified over time, and his popularity rose as indoor plumbing became more widespread. The majority of tankless toilets still use this basic architecture.

Sloan only managed to sell three toilets during his initial two years of operation. However, more and more people became interested in these contraptions, and the usage of these flush valve toilets increased in popularity right through the 20th century, particularly in metropolitan areas. Sloan’s original tankless toilet is still used in public restrooms around the world today.

In other words, you have the option of performing a standard or partial solids flush. This is a useful technology for conserving water that will most likely be available on more toilet types in the future.

Another benefit of high-performance tankless toilets is their appearance. They are often designed in a sleek, modern style that takes up less space and is less noticeable than standard tank toilets.

They are also advertised as providing better bowl cleanliness performance. In other words, strong flushes are supposed to prevent any residual waste in the bowl. They also frequently have a number of comfort features, including:

  • Air purifying systems
  • Personal cleansing
  • Spray massage
  • Warm air dryers
  • Heated seats
  • Noise reduction technology
  • Hands-free automatic flushing

In Conclusion

Tankless toilets have many benefits that make them appealing for both residential and commercial use. They are more efficient than tank toilets, and their small size allows them to be installed in a variety of locations.

In addition, tankless toilets often have a number of features that provide increased comfort and hygiene. Although they are more expensive than tank toilets, tankless toilets may be the wave of the future.
