The PVC sewer pipe is broken. If it is glued on, how many years can it be guaranteed not to leak?

It is best not to use special PVC glue. Although it is a sewer pipe, there is no doubt about the pressure, but in nine cases out of ten, it will crack because of the expansion of heat and contraction of cold in Leng Xia in winter. Some users can use it for several years or even longer, but you are not a temporary resident, you have to live for decades. In order to avoid future troubles, I suggest you change it. Before you decorate it.
