I really need to move my radiator further down my wall, is there a way I can extend the radiator pipe? please see picture attached. i just want to find a way to move the radiator about 2-3 ft to the left :-(

If that's a hot water radiator, there's no problem moving it, although depending on the kind of controls you have on your system, once you move the radiator, you may have to adjust any balancing valves in your heating system.

If that's a steam radiator, I don't know enough about steam heat to answer your question. You might want to try the Terry Love Plumbing Q&A forum for that one.

I would call a plumber as he or she could make that change in a few hours would be my guestiment. Can you do it,sure. But as well as a pro, I would think not....

some radiator pipes must have a slight slope to avoid a possible air lock. Depends on the type of system you have hot water or steam

Really? If so old houses have that built in feature going for them. I always though you bleed the radiators to remove the air present in the system.

I don't know about steam, but I've never heard of sloping the pipes on a hot water heating system.

If you have hot water heating, then you have a pump that pumps the water through the pipes, and having the pipes sloping the wrong way doesn't matter.

EVERY cast iron hydronic radiator will have an air vent:

And if you have finned copper tube radiators, there will be a "baseboard tee" like this one:

at the downstream end of every horizontal radiator train for venting any trapped air as well as an air separator in the heating system somewhere.

a steam system may or may not have a condensate return pipe... commercial ones almost always do. home systems may reuse the feed line, in which case it needs a slope.

based on the plumbing I saw in the before-wife's duplex boiler and my old apartment, hot water needs two pipes, and the supply has the valve.

venting a branch is always done to eliminate air locks. in the case of a one-pipe steam system, you can develop a water lock in addition to an air lock.

if you call a pro on this, it will all be considered. if you do it yourself, you might get it right, and you might not, and you might get burned in the process.

thank you , swschrad, for clearing it up.I'm not familiar with radiator systems so I just parroted what I've seen and heard on various home shows, notably "Ask this old house " whose resident plumber has been in the business for many years, and he did mention that some homes need a slight slope for the pipe, probably for the condensate return as you suggest

Nona, sorry about my reply. You were right. Now that you mention it I did view the ATOH episode with Rich T reworking steam radiators. Slipped my mind [hard to believe] but I never see steam setups in my world..
Actually TOH & ATOH are the only two home shows worthy of their salt. IMO.
