I wanted to add a toilet in my basement. I already removed the cement and I also cut the pipe (its an old house so the original pipe was made of hard 4" metal pipe). I got the PVC pipe installation but I am not confident of the connection I made between the PVC pipe and the original metal pipe (I used rubbers but it doesn't look solid and might be leaking). These are the rubbers:
So I was wondering if you can help me out with this. Is there another way to connect the PVC connection to the metal pipe? I can't move the metal pipe around so it's a tight fit as you can see in the picture I posted below.
