Re: Ever seen one of these??
was there like a drying shelf on the bottom? looks like there are lugs to hold a shelf on the bottom.

Re: New refrigerants Epa 608
Unofficial, i hear 134a works well in r290 equipment.
Way different pressures temperatures.

Re: Support steam pipe with split ring hangers
if the threaded rod is long it will work.
if the split ring is over the insulation it will work.

Re: Magnesium anode vs Electric anode vs No anode
I did use so-called black steel pipes (honestly I don't know why they call them that…they are just steel as far as I can tell)…what kind should I have used?
I have heard people say that the glass lined tanks are really more of a baked on enamel that is prone to cracking.
My favorite tank I've ever seen is the Rheem Marathon (plastic)—I wish they offered that as a heat pump unit.

ASME Code (I know it doesn't apply to residential) used to talk about "wet lay up" and 'dry lay up"
Re: Steam pressure; always amazed folks set it high
Pressure setting is way too high. That particular pressuretrol can be set all the way down to a bit below 2 psig, with a 1 psig differential — which is the best they'll be able to do.
Re: New, unused Peerless 63-04 Brooklyn/Queens area
I have put together many push nipple boilers. The only one I had a problem with was an HB SMITH model 2000 back in the 70s. One push nipple got crooked while being pulled together but we knew it wasn't going right so we backed off before any damage. Its like making on a threaded fitting you start it and you can teel if its not going right.
All the sections set on the floor with legs. One of the legs the casting was a little short on the leg so problems can happen. We got a new push nipple and lifted that section with a crowbar and it pulled right in.
The company I worked for did some work for Buderus. When they sold a CI boiler and it was going into the building with a Crane and not individual sections they would ship the sections to us to assemble in our shop.
We had 1 tech that used to oversee the assembly in the shop. The only time we had a problem was when he was out they had an inexperienced guy do it and it leaked.
Sounds like trouble but the rate of a failure is very low. Those boilers (the Buderus) had no legs on the middle sections just the front and back and they all had to be pulled together at the same time. Buderus used to ship a hydraulic assembly tool to use.
I never did one of those myself.
Re: New refrigerants Epa 608
And yet those are running similar pressures to R22 systems that used to last 30+ years.
I've heard people blame the high pressure of 410A, obviously that's not the case on an R290 system.

Re: leaky sink trap connection
Pipe dope on the plastic/nylon gaskets, tighten hand-tight, and where plastic meets plastic. No leaks.
