My home renovation master made the drain pipe in my kitchen like this? Could it be a problem? Unders

If you don't do such a waterproof bend, you can't drain the water at all because of the large amount of drainage.

It must be made like this, this is a sink bend, the main function is to prevent other smells of the pipe from the kitchen, if you use it often, you should block it for more than half a year, mainly for long-term use, the oil sticks to the pipe to make the pipe flow slowly, and it is good to flush it with hot water for a period of time

I've never seen a water trap like this!

It's not the problem of garbage blockage, but the pipe resistance is too large, four or five 90° elbows toss back and forth, even if there is no garbage, the drainage will not be smooth, if the drainage is large, it is likely to cause the drainage to overflow from the interface!

Let him do it again, how can this be.

It is rare to make such a reverse bend, and the reverse bend is generally made to the hose part of the vegetable basin drain, mainly to prevent bad smell and at the same time to be easy to clean and maintain.

If you must make it look like in the picture, it is recommended that the two 90-degree elbows on the upper part should be the kind with access ports for easy maintenance.
