Fourth, the use time should be long enough that you don't need to change it from time to time. Some mechanical floor drains use plastic as the core. The characteristic of plastic is that it will become brittle after three or five years of use, and the core of this floor drain needs high-frequency activity, so the function of the floor drain is not stable enough, and various problems may occur, which needs to be replaced. .
Fifth, the purchase of floor drains also needs to be determined according to the place of use. For example, the flushing volume of the shower room is large. In order to ensure that the water can leak down quickly without accumulating water, the drainage volume of the floor drain here also needs to be large; in addition, the instantaneous water flow of the washing machine is extremely large, and the instantaneous pressure on the water pipe is at this time. Very big. Experts suggest that if conditions permit, the best solution is not to use floor drains, but to use special pipes for drainage. If you can only choose floor drains, then it is better to install a buffer at the water outlet to reduce the instantaneous water pressure, and use a special purpose for washing machines. floor drain.
