I have been posting on the wall on my new system. Some of the problems seem to be water hammer on a dry return. Dirty water which has cleared up. I know near boiler piping is important and was wondering what you thougt and I have been reading that a water feed should not be attached to a Hartford Loop. I included some pictures of the water feed and I'm not sure if it is attached to the Hartford Loop, below boiler water level. Also included pictures of the Gorton #2 vents that I put on the dry returns. Thanks ed
