The water trap is one of the most commonly used drainage components in the drainage system on the same floor. Now there are two types of frontal traps that are common on the market, S-type traps and P- traps. The main function of the water storage elbow is to use the water at the elbow to isolate the odor after fermentation of sewage. It should be filled with water during normal use, so that the floor drain can be separated from the air in the sewer, and the waste water, waste, bacteria, etc. in the sewer can be prevented from being directly transmitted to the home through the sewer, which has adverse effects on human health.
