Buying Guide


Power Supply

Take a look if you have a reliable supply of electricity as the toilet stop functioning without power. If your home or building has a common power outage problem, avoid this toilet unless you have a power backup generator.

Space

If you are installing the toilet without tank in place of your old toilet system, then leakage might be a problem sometime

If you are constructing a new home check if the plumbing system in the current building is supportive enough. Check if the pipes of your home or building can withstand the high pressure. The pipes should be at least 1” in size. They might be a little expensive but serves quite well in small bathrooms as they take very low maintenance support.

How Tankless Toilets Work?

In the old toilets, when the user flushes the toilet,  the water is moved from the tank by gravity. After many decades the tankless toilets were innovated which looks clean and functions as the old tank system.

Traditional toilets need a tank to push the water quickly into the bowl, allowing the water and everything else in the bowl to be pulled into the drain. Most water supply lines do not supply water fast enough to trigger this siphoning effect. The tank is an attempt to fix this problem. It holds water so that when you need to flush, there is a gallon or so of water standing by to be pushed into the toilet. Without the tank, the water would just dribble into the bowl and not produce an actual flush.

They are of a relatively new type of toilet that does not rely on a tank, however. Instead of needing to store water separately, they receive water directly from the supply line at high pressure, allowing them to produce the flush effect. In most cases, this high pressure is achieved through the use of pumps or other additions. Some commercial buildings and apartment complexes have enough water pressure to skip on this add-on, though.

Tankless toilets need a different approach to the flushing system. It does not store water anywhere but uses the water in the pipes. An electric pump is used to power the flush instead, and no gravity or atmospheric pressure is applied. In other cases, the toilets use a special storage tank supplying water to a whole building. Those pumpless flushing systems require pipes to work properly. The basic principle of this system is that it should create a violent flow that moves the solid waste out of the siphon system at the bottom.

Tankless Toilet Pros and Cons

Pros
  • They do not require extra pumps or other pieces of equipment
  • Produce a more powerful flush than a tank toilet
  • Its increased flushing power keeps your toilet cleaner for longer
  • Fill up faster and can be flushed again sooner
  • Takes less space and have more design flexibility
  • They often reduce water usage as well
  • It is very much useful for small modern bathrooms
  • The pipes supplying water of a tankless toilet are mostly inserted under the floor or inside the wall.
  • This is more environmentally friendly because there is no water leakage
  • Take less time to refill
  • More sleek and clean in the bathroom and easy to clean
Cons
  • They depend on power. If your power goes out, your toilet is not going to flush
  • Repairs and installations are complex, requiring you to hire a professional plumber
  • They are expensive, and only a few companies make them so far, including Kohler and TOTO
  • Require a relatively wide supply pipeline in the house means you need to install new pipeline otherwise high pressure from the flush could damage your pipes

Tankless Toilets: Right for Your Residental Home?

Putting a tankless toilet into a residential home is a little more complicated. Residential homes often do not have a high enough psi (pounds per square inch) for tankless toilets to function without the use of an external pump. You will almost always have to install a pump or other piece of technology for a tankless toilet to flush properly. This can be expensive and requires an expert to install the system.

Sometimes you might need to upgrade your whole plumbing system, which can raise costs substantially. Because these factors depend on your particular house, you should check your psi and whether or not your plumbing meets the requirements of a tankless toilet before moving forward with buying one. 

If you have to install a pump, your tankless toilet will not work without power. If you live in an area that commonly experiences power outages, this type of toilet might not be for you. 

Tankless toilets work best in newer homes and for those with large budgets. If you’re a toilet enthusiast or want your bathroom to have a certain design, a tankless toilet can be useful. They also work best for larger families or those who enjoy hosting large parties. These toilets also work well in smaller spaces.

Bathroom Modifications Needed with Tankless Toilets

Installing a tankless toilet might require absolutely no bathroom modifications. If your psi (pounds per square inch) is high enough, you won’t need to add a pump or anything else. 

But, if your psi is too low, you will have to install an extra pump. This pump can be installed into your wall, so you won’t see it. It will have to be installed by a professional, though. Your plumbing stacks might also need to be relocated if they are in the wrong location. Again, a professional plumber will need to do this.
