My sister in law has a toilet making noise and was asking me about it. I’ve replaced several toilet parts and thought it should be an easy fix she could handle, but when nothing she was telling me was making any sense I told her to send me a picture.

I’ve never seen a set up like this and couldn’t even track it down on google.

Is this something she can handle (we don’t live in the same town) but just needs to source parts? Rip this out and put in normal stuff? Call a real plumber?
