This item works for light cleaning. But if you have gunk use other stronger products .

Drained and filled with water, added 2 bottles. Ran for about an hour, drained and added water. Got some trash out of the system. It didn’t get it all clean, I still got some trash in the expansion tank after the system was all refilled and ran.
