When you are looking for compact, economical yet fashionable looking toilet that doesn’t take much space, easy to install and looks excellent, you need a tankless toilet. Tankless toilets always have a sleek look to them. When you enter the bathroom which has a tankless toilet, you will definitely see that how much spacious it looks. This is the reason why tankless toilets are so much used these days.

When you think to remodel your bathroom just think twice to get a tankless toilet instead of the regular ones. This is the most interesting invention which has made our urban life comfortable. The most important features of the modern toilet were the waste disposal system and the different kinds of flushing system. For quite a long time this system included a tank and a bowl.

How the tank and the 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.

On the other hand, the tankless toilets need a different approach towards 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.

Advantages of the tankless toilet system

  • Tankless toilets leave a great space for you in the bathroom to customize more amenities
  • 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.
  • The system works faster as they take less time to refill. It is useful when people are waiting, especially in a public toilet.
  • It looks more sleek and clean in the bathroom and easy to clean

Guide to buy before you think of installing a tankless toilet

  • The place where the power supply is quite well, this toilet works wonderfully. 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.
  • Check the limitation of space and the perfect place to fit the toilet. If you are installing the tankless toilet 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.
