In December 2022 (i.e. 5 months ago) I had a full system power flush conducted. Now the previously clear UFH flow gauges are black again. Is it possible that enough internal corrosion could have occurred in this time period?
I had a separate plumber out a month ago to test some pipework and he said it had a lot of debris in it so I am questioning if indeed a full system power flush was done as had assumed it would stay clear a lot longer than it has.
Thanks in advance
