Hello All,
In my 3 story (plus basement) 1901 townhouse the top floor radiators
are hot on the bottom half and cold on the top half.

It's a hot water system. The piping is original, the Burnham boiler
is 14 years old. It has a circulator, but no pump. In the last three
years the following parts have been replaced:
- Expansion tank
- Pressure safety relief valve (Watts Regulator)
- Feed Water pressure regulator (Watts)
- Pilot
- Every radiator valve and bleeder throughout house

That's about all the parts that can be replaced

The pressure is set to 15 lbs.
The circulator is a Taco Cartridge Circulator, 1/25 HP, 3250 RPM

Today the carpenter and I removed one top floor radiator which is
going to be relocated a few inches in about a week or two after some
remodeling. We drained about 10 buckets of water, removed the
radiator and ran a pipe between the feed and the return of the removed
radiator.

We filled the system back up, but all 3 top floor radiators won't fill
all the way. The bottom half is hot, the top half is cold. When I
open bleeder valve only air comes out, no water. How can I get the
top floor radiators full?

Please bear in mind, they may have always been like this and I'm only
noticing it now because I'm paying attention to it. Or maybe we
caused this problem by draining the system only partially. When we
refilled we didn't bleed each radiator from the ground floor up. We
bled them after it was full. Which I know is wrong to do when you are
filling an empty system, but is it ok to do it like that if the system
was only partially drained?

Either way, any tips on how to fill the system to get the top floor
radiators full? I remember when the plumber was here 2 years ago and
drained the system to replace some radiators. He said it was a real
pain in the plumber's crack to refill my system and get the top floor
bled. He had some tricks of the trade he employed to do it. I just
wish I could remember what he told me, specifically!

He doesn't work at that particular company now and I can't track him
down to ask his advice. Before I call in a plumber and cut off my arm
and leg (you know, to pay the bill , what's your advice?

Thanks,
Rogue Petunia
