Disadvantages of Tankless Toilet

Difficult To Install

Expensive Installation

A residential tankless toilet usually costs more than a traditional model because of the additional labour involved in installing it. In addition, a flush system with an electric pump is significantly more expensive.

Creates Noise

A tankless toilet is much louder than a tank toilet when flushing. You can generally hear the noise when you flush due to the electric pump that operates.

The pump creates high-pressure water flow when flushing the toilet which causes a lot of noise. In addition to the increased water flow, there is an increase in sound from the flush.

The traditional kind is much noisier than the models that include sound insulation. There can be a significant problem with this in smaller homes especially in ones that do not have adequate sound insulation.

Higher Water Pressure Damages Pipes

There is also the issue of constant high water pressure in tankless toilets since water comes directly from the pipes and it creates the noise.

In order to provide a longer service life, it is better to use wider and stronger pipes than average pipelines that can only withstand a certain amount of pressure. It is possible for these to withstand pressure for years without cracking.

You might experience greater pressure and even cracks in your supply lines if you use the usual pipes. A tank toilet rarely experiences this problem.

You Need Water Filters

Make sure that your tankless toilet comes with a built-in water filtration system. You should also get an external filter for improved performance and cleanliness which is not an issue with a tank toilet.
