Just be aware that the stuff that is probably blocking the elbows can be really tough to shift even with a metal wire trying to clear it. What you don't want to do is make it loose and then push it around the system where it can block somewhere else.
You have to be brave when trying to clear it with large buckets at the ready and best to replace the elbows once cleared.
