Toilet Flush Terminology

One of the things I hope I have managed to do when putting this website together for you, is to make sure that you’re not baffled with science. Yes! There is a certain science to toilets these days! Manufacturers are generally very good at telling you what features their models have, but because they are experts in their field they don’t always make it clear what something means. This is why I’ve added this section for you.

Perhaps you were in the middle of a review and didn’t understand what a particular type of flush means? Rather than have you go searching on the internet for the explanation, you should be able to find everything you need here.

Below are some of the more common terms you may come across when you’re looking for a new toilet.

Low Flush/Dual Flush

These are toilets that use the least amount of water. What you should know is you will generally get the option of a low flush when you buy a dual flush toilet. Still confused? Well, let’s deal with dual flush first.

This means the model you choose will have two types of flush: low and high. On low, your toilet will use as little as 1 gallon of water which is well within the legal limits set out by the American Federal Government. This type of flush is perfect if you only have some light waste to get rid of and a minimal amount of paper.

On high (or heavy flush), you will still only use as much as 1.6 gallons of water which is still far less than models that were still being made in the 1980’s. Just to give you an idea, models older than this could use anything from 3 – 6 gallons of water on just one flush!

Power Flush

To explain this fully in technical terms would mean creating a manual, and the whole point of me creating this page is so you can easily understand if a power flush toilet is what you need. Basically, the technology used with this type of toilet will allow you to easily do away with as much as 1000 grams of waste in one flush! In fact, this is about 70% more than other models that don’t have this feature.

Just to give you an idea (if stating 1000 grams wasn’t enough), some manufacturers have managed to flush away a bucket of golf balls in one go without any clogging or overflowing. In short, if you have a busy household and/or you have children that keep losing various toys down the toilet, a power flush is possibly the best type to go for.

dual flush

Gravity Flush

This is the most natural type of flush you can get, and most of the budget priced models of toilet will use this because it’s not expensive to produce. There are no “bells and whistles” here. Your toilet will simply rely on gravity to take the water from the tank through to the bowl and along into your sewage system, taking the waste with it.

For those of you that have a quiet household that doesn’t require any “heavy” toilet usage, this type of flush will suit you.

Slightly off the Subject but Still Important

When you’re deciding which type of flush you would like with your toilet, think about this. US law has stated that any toilet made these days is not allowed to exceed 1.6 gallons of water for each flush. This not only helps the planet but it keeps your water bills down as well.
