Will Drano unclog the sewer line?
Take note that the sewer line is the main line from your house which is responsible for transporting the waste water from your household to the main line. It could be made from either a clay pipe, cast-iron pipe, Orangeburg, plastic sewer pipe, PVC pipe, or BAS pipe (The Spruce).
Pouring Drano into your sewer line will not unclog it but rather could harm your pipe.
The chemical content of this product could have a harmful reaction with the materials of your sewer line. Rather than using chemicals in your pipe, call a service technician to help troubleshoot the problem and fix it.
Do toilets and sinks use the same drain?
Yes, they can share the same drain. However, since they both drain at the same time in some instances, the toilet pipe needs to be large enough to accommodate the water from the bathroom sink and the wastewater from the toilet bowl.
What happens if you use a small pipe? Chances are you will end up having a leaking pipe. The pressure from the water waste is just too strong for the pipe you are using.
In a worse case scenario, the pipe would burst from pressure. To avoid this from happening, make sure that you are using the right size for the pipe – a common valve within a 1.5m radius.
Clogged pipes are the result of accumulated debris that has been built up over time.
