If you live in a family home or a home that was constructed in the 1980s or before, you will see that there are certain things that are quite unique. Take a look at the sewer system, for example. It is likely made of cast iron.

PVC To Cast Iron Hub

If you want to remodel your kitchen or bathroom now, you will have to connect a new PVC pipe to the old cast iron system because cast iron is not used anymore. Personally, we would recommend that you hire an expert to do this for you because it is not something a DIY enthusiast can pull off. However, learning about the process and which hub to pick will help you make better decisions.

Why Is Connecting PVC To Cast Iron Hub An Expert’s Job?

Cast iron is a difficult material to work with, especially if it is old. There are special tools that you need just to cut it. Also, since cast iron is heavy, it is almost impossible for a single person to handle it. 

Another point that you should consider is having to tunnel down the ground because cast iron are usually down there. 

All this adds up to extensive labor and time. Unless you are positive that you can do it yourself, you shouldn’t risk it.
