Removed insulation from any pipes. Remodeled the basement. Or changed anything in the basement. Is it a single or 2 pipe system.

The main 2 inc pipe is insulated, only one pipe is doing the knocking, I am going to see which radiator it feeds and make sure the radiator is on a slant towards the pipe. It's a one pipe system.
