We have 1 1/4″ valve on an old steam radiator system. The new valves are made so the housing is smaller than the old ones. So many times they do not fit. Can I shop around to find a bigger one? Or do we have to exted the pipe with a coupling? This would mean that we have to make a block to set the radiator on, right? Or should we rebuild the valve?? Help!
Are you talking about the angle radiator valve, you mean it is 1″ and your pipe is 1-1/4″. if that is case then you would have to use 1-1/4″ by 1″ reducer and a nipple, you would have to cut pipe. But if you can get below in base ment then take out 1-1/4″ pipe and put in acast iron bushing and run 1″ up to radiator valve, on heating you should use castiron fittings. To sole this go to plumbing supplyhouse and get a valve the right size, you can repack the old valve and buy washers for it at supplyhouse.
No, the pipe is all 1 1/4″. The valve casting itself is actually shorter, so the feet of the radiator are jammed into the floor. For example if you replace legs on a chair with shorter legs, your chin will hit the table, even though the legs are the same thickness. And if we add a coupling to extend the feed pipe the radiator will be too high and it will float in the air. This problem must happen all the time….
