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 worst-case scenario, the pipe would burst from water 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.
