What to Look for in a Toilet with Strong Flushing?

There are some fantastic high-power toilets out there that use less water, but the entire bowl gets cleaned with one flush only. Sounds amazing, right?!

There are 6 factors that impact the flushing power of a toilet.

  1. Type of Flushing System
  2. Water Consumption
  3. Size of the rough-in
  4. Wall mounted vs floor mounted Toilets
  5. Round vs Elongated Toilets
  6. One Piece vs Two Piece toilets

5 Types of Flushing Systems

Choosing the type of flushing system is paramount when looking out for a toilet that can easily flush everything in one go.

After all, the performance of a super flushing toilet depends on the flushing technology that it uses.

Here are the
5 flushing technologies you’ll find in modern toilets:

1. Gravity flush

Gravity flush toilets are the most common and cheaper option you’ll find on the market.

The cistern doesn’t have any special valves, or the bowl doesn’t have any extra holes.

The power of the flush depends on gravity only.

The weight of the water results in pressure, and water flows down into the bowl, cleaning it.

These toilets aren’t that powerful when compared to other technologies, but they give a quiet flush.

2. Siphon jet flushing

Some of the fastest flushing toilets use siphon jet flushing for maximum cleaning.

There is a siphon jet pocket inside the toilet that holds some water.

When the lever is pressed, the water inside the siphon pocket along with the tank’s water comes out with immense pressure to clean the entire bowl.

Usually, brands like Kohler and Toto use Siphon jet flushing technology in their fast flushing toilets.

3. Dual flush

Dual flush toilets have two buttons, one for flushing the liquid waste and one for the solid.

These toilets are garnering a lot of popularity as they save a lot of water.

4. Pressure-assisted flush

Pressure-assisted toilets are a bit similar to gravity flush, as the weight of the water is responsible for its flow.

However, there is an air valve fitted inside the tank, so the air also puts pressure, and the water flows quickly inside the tank.

These rapid flush toilets are powerful and can clean the entire bowl efficiently in a single flush.

5. Double cyclone flush

Toilets with double cyclone flush have bigger nozzles across the toilet’s rim.

These bigger holes let more water flow through them, and it results in the formation of a cyclone inside the bowl.

The cyclone takes away everything with it down the drain.

After deciding which flushing type is the best, it is essential to consider some other factors as well in order to make an informed decision.

Go For Low Water Consumption

It is essential to buy superior toilets with low water consumption, to save water, and to keep the water bills under your budget.

Most of the modern flushing toilets use less water and still have powerful flushing.

You can choose from single or dual flush toilets depending on the water holding capacity.

Make sure to choose a branded toilet that comes with some water-saving certification.

What Size of The Rough-in To Pick?

The rough-in or trapway is a part of the toilet that fits with the drain pipe.

Most of the toilets have a 12-inch rough-in as it’s the standard size.

However, there are some options available with smaller trapways as well.

Be careful when choosing a toilet Or, if possible, measure the size between the wall and the drain pipe to purchase a perfect toilet for your bathroom.

Round vs Elongated Toilets

Choosing the right bowl shape is imperative if you don’t want the door to bump into the toilet.

Modern toilets come in two shapes: round and elongated.

Round toilets are compact, and they can fit even in the smallest bathrooms with limited space.

On the other hand, elongated toilets look great, but they occupy a lot of space.

Wall mounted vs floor mounted Toilets

wall-mounted or wall-hanging toilets are popular because they consume less space, and that’s why they are fit for commercial use.

The tank fits inside the wall, and the only visible part of the toilet is the bowl.

On the other hand, floor-mounted toilets are easy to install as there’s no need to fit the tank inside the wall.

These toilets are ideal for use at homes and commercial buildings.

One-piece vs Two-Piece Toilet: Pros and Cons

It can be daunting to choose between one-piece and two-piece toilets.

Both of them look almost the same, and that’s why people find it hard to choose one from the list of most powerful flushing toilets.

To make things easy, we are here with some pros and cons of both toilets so that you can make an informed decision.

Pros of one-piece toilets

  • Easy to install as the tank comes connected to the bowl
  • Highly durable and lesser chances of any damages while installing
  • Easy to clean due to fewer edges around the rim
  • Requires less maintenance
