There were rats in the kitchen drain, and it felt like it was the source, and it was bitten off the

Impossible, the inner wall of the water pipe is so smooth and vertical that rats can't get up. You check it out and it must have come from somewhere else.

A layer of stainless steel cup-shaped net is set inside the sewer pipe, and the upper perimeter is wrapped with glue, raw meal tape or tape to plug and fix it tightly, so that the rats cannot go up. You can still go into the water normally, but after a period of time, it may be difficult to drain due to garbage such as food scraps, so you can clean it up regularly. Ground sewer pipe with "flange upgrade rodent-proof net, sewer pipe strainer, anti-clogging sink strainer net, round hole net".

And the part connected to the kitchen sink drain is "kitchen sink drainer single tank lengthened drain pipe wash basin stainless steel drain anti-rat bite sink fitting".

You're stupider than you see with your own eyes the kitchen drain and crawl out.

My washing tray drain pipe was also bitten open by mice, mice also came into the room from the sewer, I didn't say anything, the sewer entrance that it bit open was blocked, the doors and windows were closed, since it came, don't go, go out and turn right to buy a bottle of 502, go back to the left turn and pick up the big raccoon cat of the grandmother's house next door, hehe. Go home and pet the cat! Petting cats!

Peeled the garlic, put on cowhide gloves to put the cat, the raccoon dog spent a while to force the guests in the corner in a daze, reached out, stroked, turned over the garlic and stuffed it into the asshole, while the asshole was still open, poured 502, slightly dry and threw back to the sewer, the forehead sewer seems to have a lot of mice fighting, ignore, wash your hands, feed the cat! Petting cats!

Fill it with hot water, or put a sticky rat board at the outlet, I have to say that the sticky rat board is very effective.
