Steam

FWIW, I solved a similar problem by knowing that the legs of my rad were of course solid (no air/steam cavity in the legs), otherwise the condensate would not drain. So, I cut off about 3/8-1/2 in. off the legs to lower the rad and that took care of the height problem, without affecting the function of the rad.

RAISING STEAM VALVES

I have current steam radiators on top of old 3/8 flooring. I want to replace the floor with 3/4 however the valve coming up from the floor will need to be raised to match the radiator? Does anyone know how to raise the valve up without ripping up the subfloor, there is no play in the pipe to lift it up.

--- Also have the reverse problem in the bathroom, after removing the old 1 1/2" mud floor the radiator is way high once the new tile goes onto the new 1/4" hardibacker board. Can you lower the valve without any major problems? If not whats the solution to get a charlston pro and hang it on the wall like a towel warmer?

raising rads

You need a big pipe wrench, lots of muscle and a radiator full of luck. If the piping is concealed in the floor, your only option is to replace the riser coming out of the floor. Hopefully, you can get it to spin out without damage to the fitting below. Ditto for lowering the radiator. You could go to wall mount rads, but that can be expensive. Opening up the floor is certainly an option but doesn't always help as the space is usually quite limited between joists and using large tools in there can be a challenge, especially if the pipe is larger than 1".
Good luck. A job for a pro for sure.

How about if you replaced the valve with one a size larger?

Shouldn't affect the operation. Put a bushing on the nipple sticking out of the floor, that should give the required height gain. Then bush down the outlet side of the valve. Should work as long as there's room to move the radiator to the side a little.

Checkers

are great for raising a boiler as they are stackable, lowering is a bit more tricky, you can try recessing the floor so the legs sit in a slight depression. be sure the water can flow to the outlet though.
