The simple décor, hygienic serene, and the warmth of your loved ones are some of the best thrillers in a great home. And above all that, an awesome odor free, clean, stylish, and properly set toilet.

The Main Types of Flush System Toilet

Because toilets are an investment, you want to put your money in the best use. Therefore, you should understand the main types of flushing systems that you can choose from. Here are the major options;

1. Gravity Flush Toilet

Probably the cheapest flushing toilet, the gravity flush relies on the water in the tank to create pressure when the water from the tank is released to the bowl. Basically, it applies the siphoning action to clean the bowl. It is one of the timeless technologies that are used in many toilets even today.

2. Pressure Assisted

Second one; the gravity flushed toilet is the pressure assisted one. This model relies on pressurized air and ideally water from a separate tank to force the waste out of the bowl. Because of the pressure released by this kind of toilets, the toilets can often get clogged. They can also be very noisy. But what’s the worry if you don't mind?

3. Dual Flush Toilet

These are rather new to the market. Even so, they have been increasingly embraced today. It allows the consumer to choose a full or partial flush in order to save so much water. The partial flush option can be used for liquid waste and the full flush for the solid waste. It's great for a budget.

4. Double Cyclone

The double cyclone flush toilets are not so common today. They are a good alternative to the dual flush but are rather pricey compared to the other models. They use a far much smaller quantity of water for each flush and are the right water saver. If you want a low bill and don't want the dual flush, this is your best option.

3 Common Terms to Know When Buying the Flushing Toilet

Often when reading the top rated toilet reviews and also when describing toilet features, you will find out that there are a number of terms used to describe toilet features. They include some of the following;

When a toilet complies with ADA specification/ recommendations it means that it is designed to specific sets of specifications usually based on the 2010 ADA Standards for Accessible Design that demand the toilet seats to always be no less than 17" from the floor and no more than 19".

In addition, it expects that every toilet must have a lever flush mechanism.

2. Round/ Elongated Bowl

Ever wondered why some toilet bowls are round while others are elongated? The names come from their shapes. The round bowls take less space as compared to the elongated bowls.

Elongated ones are often much more comfortable. Because of this, round-bowled toilets are good for minimum spaces as compared to the elongated shapes.

3. Water Sense Technology

The Water Sense Technology encourages every toilet manufacturer to keep water conservation at the back of their minds. To get accredited for the Water Sense, a toilet has to be verified as being on the least, 20% more efficient than the average product.

The standard rate is 1.6 gallons per flush. So to meet this test, a toilet has to use 1.28 gallons of water per flush or less.

Common Problems that Flushing Toilets Face

Like any other product, flush system toilets also have their challenges. This is especially true if you have chosen the wrong product if the toilet experiences high levels of wear and tear, and above all, in case of poor installation. These problems include the following.

Random Flushes

Sometimes, your toilet can flush randomly without having to prompt them. This can be worrying and can also lead to so much waste of water. It is often caused by water leaking into the bowl due to a perished or damaged valve. The valve can always be replaced to restore efficiency.

The Weak Flush

Even though it is good news that most right flush system toilets today use the Water Sense Technology, this technology can sometimes leave you with a weak flush. This can often come as a result of poor installation. Hence, it is always advisable to follow every instruction when installing the toilet.

Overflowing Toilet

Overflowing toilet means that the more you flush your toilet; the water keeps rising instead of flowing out. This will signal only one thing; a clogged or backed up toilet.

This is often caused by sank drainage system, burst up drainage pipe, clogs from non-toilet friendly materials such as hair, wipes, diapers, and toys. In these cases, always call a plumber to help.

Running Toilet

Running toilets are usually a bother. They cause very annoying noises and wastes so much water too. This problem is often caused by a flapper valve that doesn’t close properly. Always check if the valve is stuck with anything such as mineral deposits. If not, you should replace the flapper valve ASAP.

Dripping Tank

Water dripping from the toilet tank is another sickening problem. It could look really simple, but it could also mean worse. It could signal a cracked tank, and more importantly, a pointer to greater water wastage. In case of a dripping/ leaky toilet water tank, look for an expert plumber to help out.
