NTI Trinity 150c and need to flush
My installer DID NOT flush the system prior to installation or during. The warranty papers from Trinity say this could invalidate my warranty. The installer said it is not mandatory but the way I read it, I think it was. Now, I just began "bleeding rads (Old cast iron) and see clear water but a lot of little flecks in the water. Is this because they did not flush and is m,y warranty in trouble? Should I do anything? If yes, what?
