Why can t the toilet urinal drain go down the drain?

There should be something blocked, first use a hook wire to reach in to hook out the blockage, and then use a cloth mop to aim at the water outlet and pull it repeatedly, and it will generally pass.

It may be that the slope of the sewer pipe is not enough, or the sewer pipe is blocked. Willing a lot. You call the workers to dredge ha, look.

If it's blocked, find a professional repairman to see.

It must have been a plugged toilet pipe. I guess there's something sundry.

When did it start? Is it an old house or a new house? If it's an old house, it may be caused by hair!

It's also possible that something else (like a sanitary napkin) is clogged! If it is a new house, it may be that the slope is not enough, but it may also be that the wall tiles are falling into the cement, so it is recommended to poke it with iron bars or steel wires first.

1.If there is a foreign object, find a professional cleaner!

2.If the time is too long, scale has formed, soak it in hydrochloric acid and rinse it off, or it can be used to clean!
