Reconnecting radiator - 1in stretch
The plumber renovating our 2nd floor bathroom (doubt if he knows anything about steam) disconnected the radiator prior to redoing the floor. I dont know if he supported the riser in any way but it doesnt seem like it - and now I moved the rad back I see a 1-1.5in diff presumably because the riser has dropped a bit under its weight. I would guess this is normal when a rad is disconnected but would like to confirm.
It kinda makes some sense as we have also noticed a bit of water hammer in the ground floor bath's rad - and these are the only two feeding off this short main. So probably the whole thing is sagging under the weight. Unfortunately we just finished the basement reno and the main is soffited away next to the beam... so I cant be sure if it had anchors - or check if it really has poor pitch.
Pipes are (I presume) original to the 1930's house. Do you think it's safe to get him to lever/jack the fitting up to reconnect the rad (and hopefully correct the main pitch... and maybe anchor main afterwards if I can get access) - or are we likely to shear something off and are better just extending? I saw a similar thread a while back but no conclusion.
Thanks for any input
