Update on my end. I had accumulation for the first time this year on monday. The morning had showers then was sunny in the afternoon. Then today was more sunny than monday with clouds in the morning but no rain but accumulated less than monday. Im wondering if the extra accumulation had something to do with the water drops on the roof. Needless to say things seem to be working as expected.
I’m glad it works. Perhaps the rain has cleaned it. You need to keep it sparkling clean for it to work.
