I backflushed the heater core again today, and as happened last December, I got out some junk and the heat instantly returned. Attached find a shot of my set-up. The green garden hose is the inlet, and I have a ball valve on it for local control, and the clear tube on the right is the oulet to a bucket. This time I had my 9 year old run the outlet water through a fine sieve, and the 2nd shot is the total gunk I got out of the core. It's maybe a rounded teaspoon at best - i'm surprised this could stop up the heater core, unless the tubes are corroded nearly shut.
