What does this debris look like to you? Discussion Thread
We've recently done a power flush on a system that's already been power flushed twice within the last 5 years. System boiler with an unvented HW cylinder and 3x UFH manifolds. Quite a large house. Strainers installed before each manifold - fully clogged.
The stuff we got out of it looks like in the picture below. My guess - the green/yellow stuff is bacterial growth, but some of it feels like sand, which I can't explain.
What does that look like to you?
