Cleaning Return lines

james_23

How could I clean the return lines in my one pipe system.
Would I have to cut them open?
Thanks..........

replace with copper pipe

you are wasting your time cleaning them. it will never happen.

I have copper return lines. By cleaning, I meant to flush out the lines so the system would perform better.
The lines currently get warm, I would guess that the returns are working. I do lose a little water in the glass though every week.
Thanks
