Why Traditional Houses Should Avoid Using Siphonic Toilets

Common toilets generally fall into two categories: siphonic toilets and washdown toilets. However, many homeowners choosing to renovate old houses prefer washdown toilets. Why is it that old houses are not suitable for siphonic toilets?

一、Why Old Houses Cannot Use Siphonic Toilets

Due to the fact that siphonic toilets were not popular in the early years, most old houses have installed squat toilets or washdown toilets. To ensure that the toilets can drain smoothly, the drainage pipes in old houses typically come equipped with a trap (anti-siphon) bend. Unfortunately, drainage systems with trap bends are not suitable for siphonic toilets.

Most siphonic toilets come with a built-in trap bend. If the trap bend in the bathroom drainage is connected to the siphonic toilet, it can lead to poor drainage or clogging during flushing. Therefore, when renovating old houses, it is generally not recommended to install siphonic toilets; instead, it is best to opt for washdown toilets. In modern new houses, there are no such restrictions, and homeowners can choose either type of toilet freely.

一、Advantages of Siphonic Toilets

1、Siphonic toilets are known for their quiet operation during flushing, thus they are often referred to as silent toilets. Additionally, the flushing power is relatively strong, which makes it easier to wash away stubborn stains on the inner wall of the toilet.

2、Siphonic toilets are typically equipped with a trap bend, which can retain more water. This feature effectively isolates unpleasant odors from the toilet pipes, improving the overall air quality in the bathroom. Moreover, siphonic toilets generally use less water compared to washdown toilets, contributing to water conservation.
