Water used in daily life such as toilets, bathtubs, washbasins and kitchen sinks is processed through drain pipes. PVC pipes or cast iron pipes are used as drain pipes. There is a high level of dissatisfaction. The noise between the upper and lower floors of the building is too high and the noise is getting higher as it goes down to the lower floor. Recently, the government has set the level of the noise below 50㏈, adding to the burden on the construction industry. Among them, the noise of the toilet and the noise of the water falling from the toilet are at their peak, causing problems that are annoying to life.

Examples of new products used in toilets in recent years include a toilet dedicated pipe LS100 (P.V.C), a low noise triple elbow (P.V.C) for a toilet, a low noise curved pipe (CC, CP; cast iron pipe), and the like.
