No. It's a steel fire-tube boiler.

We need sss - size, spacing, species of the joists. Trampoline floors are common. You can have a beam added to cut the span in half. There'll be much less bouncy-bouncy. If it even bothered me, I would just put a pad or thicker tablecloth under the dishes.

That's a bit early to declare a New Yorker boiler to be crossing the threshold to eternal rest. I don't see any from the 1970s anymore, but plenty from the next decade still working fine. Your tech might be doubling as a commissioned salesman - very common in these parts. They're a very simple, basic boiler that's very easy to service. Although New Yorker was bought by Dunkirk, parts are readily available. The most common problem is the domestic hot water coil gaskets always crack, leak and need frequent replacement. Then, the techs don't properly tighten the bolts. If you want to replace an oil-fired boiler with another oil system, there will be no significant increase in efficiency. The only advantage would be getting the right size boiler for the home. Almost all of them are oversized. The installer upsizes it to avoid possible call backs for cooler showers when the system is working hard during really cold weather.

It looks like a copper stub-out elbow, specifically for transitioning to PEX.

Joe, reread the other replies. They're clearly discussing the lever is for the combustion air damper, not the damper in the flue.

Occasionally, I'll see stainless steel piping.

They do. The holes are for inserting the tools that agitate the dirt.

It's where they inserted the "pneumatic agitation tools".

I don't understand GREEN. Are they Hunter Green, Forest Green, Chateau Green, Mint Green, Emerald Green, Empire Green, Pastel Green, Evergreen, or Veridian?

You guys must be talking about static pressure. Not as useful as measuring flow rate and flow pressure ( =capacity at point of use ).

A hose bib can be as low as 8 PSI if it supplies a minimum of 5 GPM during "peak demand".

Without seeing it in person, poking and probing, I couldn't offer a guess at a cost.

'Cuz you didn't read it. 😄

Looking at small pics on my phone, I'll bet the sills have issues and not the brick foundation.

That's not what I wrote but I will clarify. Cattle and goat hair was just more widely used and much more of it was readily available. Horsehair was much less common in plaster and was more desirable in other products.

Very, very unlikely that it contains any type of asbestos. It's more likely to be in newer plaster (the type that's been applied over rock lath) and joint compounds used in the '40s through the '70s. Cattle hair and goat hair is the most common fiber in 18th, 19th and early 20th century plaster.

I don't keep a count, but I'm sure I've checked thousands. They're extensively used in the types of buildings I inspect. Office buildings, (including every server room ever) retail, restaurants, old buildings with multiple additions and historic buildings that ducted installations would cause irreversible damage. I also have a friend who owns a top HVAC firm for almost 40 years that was one of the first to import ductless systems. The estimated 20 year lifespan is conservative. Some have made it to near 30. These were all manufactured in Japan. Now there's been a change. Over the last 4 or 5 years, the systems have all been manufactured in Korea or Taiwan (even Mitsubishi). There is no way to decipher the age from the serial numbers on these recent systems. I also don't yet know the life expectancy of the new heat pump systems with inverters.

In addition to the R22 issue, contractors will insist both sections need to be replaced to meet the minimum SEER. Split ductles systems are consistantly lasting to about 20 years - except for the circuit boards.

Usually, the 11th digit is the year it was manufactured. Could be '83, '93, '03 or '13. If it's after they were taken over by Bosch, it's a longer number sequence with no date code.

I remember back when homes had shady front porches.

Wow, that's an amazing building. I recently checked out a large 4 story lift - original to the 1870s building that was a carriage factory.

Katen's got a forearm like Popeye.

Perpetual whack-a-mole as new spots will appear. Why the screws? The gaskets are likely going to fail soon. The major advantage of selecting standing seam is the elimination of exposed fasteners. I would advise applying a preservation coating system. http://preservationproducts.com/roofing-systems
