Upstairs flushing toilet, there was a ticking sound on the roof of my house, once I was not at home,

It may be that the pipe is not connected well, there are only two ways, one is when no one uses it, see what is not connected well, the second way is: to remove the odor, buy a box of cool oil, open the lid, put it in the corner of the toilet, pay attention to the best try not to wet the water, and please use a knife to scrape off the upper layer of cool oil every once in a while, because it relies on the volatile cool oil smell to remove the toilet odor, so after the upper layer is volatilized, scrape with a knife to reproduce the lower layer. Anyway, scrape again every once in a while, depending on the situation, the main purpose is to remove odors.

It should be that the water level of the sewer well is high, and the outlet of your main pipe is blocked, and the air in the upstairs drainage pipe cannot be discharged, and it is discharged from your toilet, and you have to ask for the water from the well of the flower bed to be discharged, and your sewer pipe will be exposed to the water, and the problem will be solved.

I judge that the sewage pipe under your toilet is with an S bend, the toilet is relatively sealed after installation, the toilet has its own S bend, and the water is relatively slow when the two S bends are drained due to the internal air pressure, and it is recommended to install a vent pipe in the place where the toilet and the ground are linked, so that the internal air pressure is reduced, so that the drainage is smooth, but there is a disadvantage that it is easy to return to the smell. Some toilets have holes for installing screws on the base, and these two holes should not be sealed when installing, which will also have an effect.

This is not to say that the smell comes from the side of the toilet, their flush should be the smell of leaking from your house, you can replace your floor drain with one that anti-odor, which is also sold on the Internet.

The upstairs flushing toilet is leaking, if it is serious, you can negotiate with the upstairs residents and talk well. >>>More
