@ April 10, 2014 4:05 PM in Thanks,Dan H.!

It was a nice surprise. I really enjoyed being with everyone last night.

Thanks, guys!

The future's so bright,

@ April 3, 2014 4:55 PM in Vents spraying water

The water got contaminated during the work and that's creating wet steam.

One-pipe often has a wet return.

@ April 3, 2014 3:55 PM in Vents spraying water

Or the main continues back to the boiler, where it becomes a wet return. Is this a counterflow system? The mains just end?


@ April 3, 2014 2:29 PM in Vents spraying water

On the end with the squirting radiators, does the end of the main drop to the floor at that point and return to the boiler below the boiler waterline? 

Couple of questions

@ April 3, 2014 11:56 AM in Vents spraying water

How long is each piece of the new pipe?

What size is the pipe?

What is the pitch of the pipe? How many inches pitch over 10 feet?

What size is the radiator?

What type of radiator is it? Can you take a photo of it?

What size is the supply valve at the radiator?

Thanks, Jammer.

@ March 21, 2014 8:09 PM in Pump with integral air vent

B&G had what they called their Air Control Booster Package when I was starting out. The impeller spun the air to the putter edge of the volute and a volute-mounted vent spit it out. The price was too high and they discontinued it. Neat idea., though.

Everything old is new again.

That's the air going back into the system. Steam systems breathe, just like us. When steam forms, it expands 1,700 times, pushing the air out of the vents. Then the steam condenses and shrinks, and the air comes back in. Happens on every cycle.

Ray's book is great.

I've moved your post to this section.

@ March 14, 2014 5:34 AM in Steam boiler questions

It's a high-pressure boiler, used to make heat, to iron clothes in this case. You can't use it on a heating system for a building because its steam nozzle is too small for low-pressure steam. It's a used boiler and worth whatever someone is willing to offer you. It would help if you posted the location of the boiler. Thanks.
