Moved radiator. Will it bang?

GregWeiss

Had a radiator moved for a bath remodel.  The new piping doesn’t look quite right.  Can you all advise?

Fits in great with all the other piping.
Water? Steam? One Pipe, 2 Pipe, Monoflow (hopefully wasn't).

The reduced pipe size might be a problem. Can you post a pic of the radiator itself?

GregWeiss

This is one pipe steam.  The radiator always had a 1” supply coming up thru the floor.  

Steamhead

As long as the pitch is correct, it should work fine.

Why was the size reduced on the horizontal?

Hi Gerry.  I don’t know why the plumber did it like that.  Maybe they’re not familiar with steam.  I don’t recall seeing bushings in my steam pipes besides at a radiator.

It MAY be ok, but I'd rather see a Proper Reducing 90 degree elbow than a bushing. It could ship water up with the steam as it passes over that condensate puddle.  Tell the plumber rags are cheap....wipe that dope off..neatness counts!  Mad Dog 🐕

I agree with @Steamhead it'll probably be fine

I also agree with @Mad Dog_2 someone, anyone, should wipe that excess dope off. It's only going to become much harder to do after it gets hot.

Yes..Lots of unsightly piping jobs often look much worse than they actually work, including Steam headers.  Mad Dog 🐕

That runout is counterflow, or should be, so the condensate is flowing from the smaller to the larger pipe. It won't back up. That said, I would have used a reducing 90 as well.
