I have an OCS Cast Ray rad being installed next week. When I got it home while rolling it upside down to move it--kind of heavy--I heard a rattling of some loose metal. One side had a circular piece near the input--probably from the threading machine; luckily it was right near the input hole and I just took it out. It was about 1.25" wide metal donut that when I put any stress on it broke in half. (See photo below.)
But on the other side near the top of the rad I've also heard the rattling. I tried to use a heavy magnet to lead it out but couldn't do it. Tried flushing. The installer will be power flushing after he installs cleaner in that zone. But my concern is if the piece is too big to pass into the 3/4" system piping through the 1.25" input/output that it will block up my entire zone --piped in series and I won't know where it's stuck and then we've got a big job! Note that this rad is 2nd to last in the zone before the final old cast iron rad then 3/4" return.
The dealer will stand by it and give me a replacement but it's frign heavy so I'd prefer not to have to do that. What would you do if this was in your home? Installer will be using Adey cleaner but not sure if that would dissolve something like this, assuming it's the same kind of piece in the photo below.
