Understanding the Difference Between Grade 1 and Grade 2 Water Efficiency Toilet

19/12/2024 | Hawkrown

Toilets are commonly used sanitary fixtures in daily life. During the purchasing process, many people are unclear about the differences between first-class and second-class water efficiency toilets. Let’s take a look.

一、Differences between first-class and second-class water efficiency toilets

Difference 1: Water consumption

A first-class water efficiency toilet has a flushing volume of four liters, while a second-class has a flushing volume of five liters. Therefore, first-class toilets consume less water and are more energy-efficient.

Difference 2: Price

First-class water efficiency toilets are generally more expensive than second-class toilets, as they typically have better performance, including aspects such as flushing noise.

Difference 3: Flushing power

The flushing power of a first-class water efficiency toilet is generally weaker than that of a second-class toilet.

二、How to evaluate the quality of a toilet

1、Water consumption:

Older toilets require a lot of water to flush away waste completely, and they consume more water compared to siphonic toilets. However,after improvements, both siphonic and washdown toilets have similar water

consumption, with the latter being slightly higher.

2、Flushing power:

Utilizing water pressure and a special vertical pipe design, theflushing power of washdown toilets is greater under the same water usageconditions, while siphonic toilets exert comparatively less. The flushingeffectiveness affects cleanliness; if the inner wall of the toilet easilyaccumulates stains, a washdown toilet may be more effective.

3、Flushing noise:

While toilets cannot achieve absolute silence during flushing,washdown toilets generally produce louder noises due to their more forcefulflushing action. Siphonic toilets, on the other hand, create less noise due to theuse of pressure and differences in water levels.

4、Pipe unclogging efficiency:

The flushing function of a toilet is not the onlyimportant factor. If the toilet’s pipe gets clogged, it can be a disaster.Washdown toilets tend to have better clogging resistance than siphonic toilets, astheir direct flushing design allows waste to be cleared effectively, makingunclogging easier.

Conclusion:

The differences between first-class and second-class water efficiencytoilets have been introduced here, and I hope this information will be helpful toyou.
