It may have an adjustable differential

remove the cover (WITH THE POWER TURNED OFF) take a picture and post it here. 

I generally

drill and tap up to 1/2-inch pipe thread. Drilling becomes very unwieldy in larger sizes, so we call in the welder for these.

Anything lower than halfway down

will allow water to back up in the vent piping. See my signature pic for an example.

I'd be looking at

@ June 14, 2014 12:12 PM in Hoffman Boiler Feed, persistent trickle feed and overflow

changing back to gravity return. 90% of the condensate tanks I've seen are unnecessary. This would not only get rid of the pumps, but also any F&T traps that were added.

Here's one we installed

which is controlled the same way yours should be:

My usual phone

does take better pics- this is an older one that I keep for vacations, when I only want certain people to be able to call me. Next time I'll have a real camera with me.

I'm told there are certain places on the Net where that term could make me a LOT of money......


The Lovely Naoko just rolls her eyes, but she knew what she was getting into and married me anyway. I must be doing something right, since we just had our 10th anniversary.

Well, that's the best reason

@ June 13, 2014 12:49 PM in Name this part

that it's no longer in service.

See if you can find a name on it. Maybe you'll get lucky and discover it's a Breckenridge!

Is the leak

@ June 13, 2014 1:08 AM in Princess Model

at the joint between two sections? If so, all you probably need is to replace the push-nipple that joins the sections.

I got the tour

@ June 13, 2014 12:41 AM in Steam-Heated Hotel!

this system once heated the entire hotel but now covers only the public areas, and the head of maintenance is trying to talk the owner into completely tearing it out.

The boilers are a twinned pair of Dunkirks, badly piped as usual. There is the usual unnecessary boiler-feed tank and extra F&T traps that add moving parts to the system. The tank has only one pump feeding both boilers so there are probably water-level issues as well.

I was not able to get to the ends of the steam mains to see if they are vented. They couldn't get a hold of the keys to those rooms.

The manager I talked to, one of the family that owns the hotel, is not opposed to restoring the system. He says he will have us come up later this year, and this time we'll have full access.

I saw an old chain wrench hanging from a cut-off pipe in the boiler room, and took a couple pics of it.

The last pic was taken from our room, which looks out over the valley where Uniontown is. The sun was trying to break thru the fog that resulted from an earlier  severe thunderstorm.

I hope we got to this in time.

It's a very old main vent

@ June 12, 2014 11:01 PM in Name this part

which uses a carbon post as the expansion member.

You say it "was" on a return line?

This Plumber

@ June 11, 2014 5:32 PM in What are the implications of reducing radiator count on a one pipe steam system

sounds like he's creating more work for you to pay him for, either because he hates steam, or just to make more money.

Keep the steam in those rooms.

Steam is also a great way to heat an addition. We've done a few this way and are working on a small one now. I'll post pics when it's done.

You got it

@ June 11, 2014 5:24 PM in Radiator identification needed to get EDR.

and you can find them in Dan's book "E.D.R.".

Got a couple pics

@ June 11, 2014 5:00 PM in Steam-Heated Hotel!

just off my cell phone, so they're not great, but here goes. These are two of the radiators in the lobby. Manager isn't around, doubt if I could get a boiler room tour this time.

Anyone else know of a steam-heated hotel?

Steam-Heated Hotel!

@ June 10, 2014 6:33 PM in Steam-Heated Hotel!

at least partially- our room has one of those wall-shaking PTACs. The Lovely Naoko and I are on a short vacation and we stopped here- there are some glorious (Richmond?) ornate one-pipe steam radiators in the lobby and other common areas:

I'll get some pics if I can. 

That's a new one on me

@ June 10, 2014 11:27 AM in Ever seen this rad?

can you get a close-up of the valve?

The first two

@ June 8, 2014 12:56 AM in Radiation Identification

are probably National Panel radiators. See page 152 of Dan's book "E.D.R." for dimensions and ratings.

The third is made up of several standard wall radiator sections, which appear in the same book.

That boiler

@ June 8, 2014 12:41 AM in Wife HATES old steam radiators. Don't care for covers. Alternatives?

can be fitted with a probe-type low-water cutoff that doesn't need to be flushed- just needs to have the probe pulled and cleaned once a year. You'd have to move the pipe connection to the indirect tank, but that's no big deal. Here's a pic of one of our W-M Gold installations with a probe-type low-water cutoff and a Carlin gas burner:

Once they are stripped and painted properly

@ June 8, 2014 12:08 AM in Wife HATES old steam radiators. Don't care for covers. Alternatives?

they'll look fine. You can also detail the elevated parts of the cast-iron in a contrasting color to make them really look sharp.

You will NEVER be happy with "scorched-error". Keep the steam.

What make and model is your current boiler?

If they're getting that hot

@ June 7, 2014 6:58 PM in Wife HATES old steam radiators. Don't care for covers. Alternatives?

the system may be running too much pressure. Have it checked.

Are you having a gas conversion burner installed or going with a completely new boiler?

If you can't find MILVACO's diagram

@ June 5, 2014 5:16 PM in Does anyone remenber the Milwaukee Valve Company

don't sweat it. If your system is like other MILVACO installations I've seen, it's pretty much standard Vapor, similar to Dunham, Webster etc. using an Air Trap and Return Trap. 

On this one

@ June 1, 2014 1:06 PM in One of the worst-maintained oil-fired boilers we've seen

there were several options for domestic hot water. We went over each one and this was what they went with, even though it cost more. I think they expected this equipment to last as long as they were in the house, and of course they had several future teenagers so abundant hot water at less operating cost was key.
