Removing dip tube in Richardson el

Fizz

Anyone know how to remove Richardson system dip tube from return of radiator?

it should

be threaded and screw out of the radiator stub...why would you want to though?

Removing dip

Radiator doesn't heat, steam gets to valve, and occasionally will heat top of 1st section.  Have had valve replaced with Mepco orificing.   Radiator is on 2nd floor run off riser, only one heated off it.  System is running on 2-3 oz of pressure with vaporstat, but even when I had pressuretrol, still didn't heat.  converted from oil to gas, and rad has always been under performer.

Steamhead

Try

cleaning the little hole in the tube that acts as the air vent.

That was

my play, just concerned about running into any problems with removal of tube.

Fizz

Listened to return

pipe opposite supply riser using stethascope, sounds like faraway toilet or gravel sand with occasional thump or sound like muffled thud, not metalic.  Haven't removed tube yet, will do tomorrow, but had to get feedback on sounds in return.

Removed dip still no heat

Removed dip, air hole clear, didn't remove ball check from elbow,but rotated and cleaned with cloth, no residue on cloth.  Still no heat in radiator.
