Knucklehead Mania!!

Hello everyone! I thought I would show some work that a knucklehead did in my house at some point in the past before I lived there. Now my kitchen rad and 2nd flr bathroom rad have never operated correctly like the others in the house. Kitchen rad takes a long time to get heat, and the 2nd flr bathroom rad rarely ever heats but sometimes on a long cycle in the super cold, but not always. I do know that the kitchen rad was moved in the past. From what I can figure out is that someone remodeled the kitchen and also changed a bit of the layout. I guess when they started moving and remodeling things, there were some pipes in the way. So they rerouted some plumbing for the 2nd flr bathroom along with the steam pipe that was originally attached to the capped off run out I found off the larger main in the basement. Then they decided to use the original kitchen rad run out and connect the kitchen rad's new location with copper as you can see in the pics, along with hacking up some floor joists. To make matters even worse, they placed a copper tee in this new run out and branched the 2nd floor bathroom's rad off of this!!! So you have 2 rads on one copper run out with a smaller diameter pipe. Sounds like this guy knew what he was doing! Knuckleheads! There usually is a banging in my kitchen wall during longer cycles. Now to fix all of this I think the kitchen rad will be the easiest, get rid of the copper pipe and put in proper diameter black pipe and reinforce the hacked up floor joists. Also at this point I think I would have to run the new pipe through the hacked up joists. For the 2nd flr bathroom, not so easy, I am going to have to open one of the walls (approx. original steam pipe location) in the kitchen as well as part of the ceiling to pipe the original capped off run out in the basement to the 2nd flr bathroom rad. Now the locations of the copper run out to the 2nd flr bathroom rad and the location to where the original run out connected to the rad are different, by I would say 8-10 feet and ran up a different wall, not the original wall. So I really hope no floor joists for the second floor under the bathroom were hacked to run that copper pipe to the rad, because you can see that the kitchen ceiling was opened up at some time. Of course I would like to get this all fixed eventually because the system will never operate correctly unless it is done and my wife always reminds me that the 2nd flr bathroom is cold. I learned a lot from reading We Got Steam Heat over the course of last winter and recently @Dave0176 did see most of this wonderful knucklehead's piping job. Thankfully from what I can gather, the rest of the house's rads and original piping off the 2 mains have never been touched with 1 exception. The rad in the master bedroom was flipped to the other side of the pipe which I suspected due to it was not in front of the window and I found rad feet impressions in the hardwood flooring. Measurements confirmed this. But no problem with the master bedroom rad, it works well. So I just thought I would share this issue on The Wall for everyone to read about. Any questions or thoughts, please ask. Also please comment if you wish.
