In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have a 12 storey apartment building with 1 pipe steam, I have to replace the pipe work between the radiators and the risers. Originally it was 1 1/2" , I don't see a problem changing to 1 1/4" - does anyone else see a problem with this? All the run's are less than 8 FT from the riser to the radiator.
