What should I do if the kitchen two-way sewer pipe and dishwasher drain pipe always overflow?

What should I do? What else can I do? Of course, try to block it! Since the sealing plug of the well-known brand submarine is not big enough to seal, then change the brand or change the method! Before changing the method, let's find out what a "two-way sewer" is.

Brief introduction of two-way sewer pipe: The so-called two-way sewer pipe is also a Y-shaped pipe joint, and drainage pipe joints such as "straight" or "tee" and "elbow" have different uses! "Two-way connector" is used to combine two "waterways", which is commonly known as "water contact" in our local area! And the real name of this Y-joint is 45-degree oblique tee! (pictured)

When this tee is used as the joint of double-channel drainage pipeline, when one drainage interface needs drainage, it will overflow from the other interface. Why is this happening?

The first reason is that the installation is not vertical and the inclined drainage position is excessively inclined. When the displacement of the vertical drainage body is too large and too fast, it will flow out from the oblique drainage body. The second reason is that the sealing work of the drainage pipe (hard throat) of the equipment is not good enough after it is connected to the drainage outlet, and the sealing plug is not big enough to seal it, so that when one drainage outlet drains water, most of it may overflow from another drainage outlet! The third reason is that the main drainage pipe is blocked, and there is a possibility of backflow if the drainage is not smooth enough. So, how to deal with these situations? The method is as follows:

1. Dredge the sewer: Since it is suspected that the blockage of the main drainage pipe will slow down the drainage and lead to the possibility of backflow, it is necessary to dredge the sewer first. Since the kitchen is connected to the drain pipe of the dishwasher, something greasy may be blocking the drain pipe, so boiling water can be used. Rinse with white vinegar, or use caustic soda as a "greasy nemesis" to help dredge!

2. Replace the sealing plug: If you feel that the sealing plug is not sealed enough, replace it yourself. If everything is handled after the product is sold, there is no reason to need many people to help you with unconditional service!

Visually, the 45-degree oblique tee in the picture provided by the subject is dedicated to 75 pipes, and the drain hose of the dishwasher is equivalent to 50 pipes. We can buy a 50-pipe drain hole and directly "fit" it into 50 pipes and put it on the 75-pipe oblique tee to make the drain pipe of the dishwasher more sealed! (As shown in Figure 75, the pipeline is changed to a 50-tube adapter.)

3. Thorough sealing: If the above methods are still not enough, then after the two "waterway" drainage pipes are connected, they can be sealed with sealant (glass glue) directly, so that there will be no water leakage. Are you afraid it will leak?

Yuge's home can also be "sealed" directly with sealant and glass glue, but it is more troublesome to replace the drainage hose in the future!

If it is too troublesome, you can buy various porous drainage connectors online. These little things are really airtight! And the installation method is simple and convenient, and it will be easy to see! (pictured)

In fact, it is not difficult to solve this problem. As long as the main drainage pipeline is not blocked, there are many ways to completely seal the interface without overflowing. Friends, do you find it difficult? Try it according to the method mentioned above by Brother Yu, and you will be satisfied!
