How much water?

One pipe steam system. 1year old burnham boiler. Water line drops approx 1" every 2 weeks. 3 of my radiator valves have slight leaks.

Is this a normal ammt of water to add? Obviously I need to fix the valves.

    It's not that evil...

    but it is more than it should be if the system were tight.  I wouldn't be that surprised, though, if fixing the leaks on the valves made a big difference.  Surprising how much water a "slight" leak really is!
