Re: Circa 1920 levered manual steam valve
If they're leaking past the stem, you can repack them.
Its MOUAT.
See:
2 pipe system? Looks like a regulating valve.
Mepco still makes those, be prepared for sticker shock.
You can't just swap them for a regular valve without additional work.
Re: Where to put the pump
Flow switch, @GroundUp . Pump in the house, flow switch near the boiler.
Re: Where to put the pump
I take it there is a feed line and a return line from the manifold in the house to the carriage house? Yes? Then there is no good reason why the pump controlling the circulation in the carriage house can't be in the carriage house. The only thing you would have to watch out for is the pressure drop in the feed line from the house to the carriage house, and thus the inlet to that pump — most pumps should have at least 5 to 10 psig at the inlet when they are running.
All your control wiring for the thermostat and the pump would be in the carriage house. How the boiler would be controlled is another matter — and that depends on what controls the boiler now. It could be a flow switch on the feed or return, for instance, right at the existing house connection.
Re: Help me swap my Gorton #1 main vent (with free used Hoffman 75) ?
A couple elbows and nipples will fix that.
Re: Circa 1920 levered manual steam valve
I agree, just replacing these with standard valves will cause all kinds of trouble. Use the MEPCOs.
@gerry gill is our resident Mouat guy, hopefully he will chime in.
Re: Name this fitting
probably uses a green or blue fiber washer. The washer should always be replaced when you open the connection.
It should not need any pipe dope if both surfaces are clean

Re: Name this fitting
Thanks! That helps me a lot!
I notice there's some discoloration on the part that seals. I wonder if that's some kind of contamination. These types of couplings are supposed to be strictly metal-on-metal, right?
I am tempted to try cleaning it off. Perhaps removing the corrosion on the outside upper pipe with steel wool, and using isopropyl on the mating surface.
Re: 1-column old radiator
I like the receptacle half in the convector cabinet. Cast iron and a convector on the same zone won't balance well. The wall hung radiators were very common, more so in commercial than residential. very common to see acres of them hung on walls to heat large spaces like factories or warehouses or gyms.

Re: Oil Heat Tankless boiler coil disabled and replaced with Water Heater Changeover Questions
If my most recent diagram is correct, this is the easiest way to make it a cold start boiler.
- The red wire is all you need
- Remove the wires from the L4006B
- connect the circulator directly to the 4 N/O on the SR501
- Add a wire to connect from H on the SR501 to 6N/O on the SR501
- Remove the wire that goes from L1 power to the supply switch to the L4006A (maybe R or B)
- Connect a wire from 5 on the SR501 to the wire you removed from the L4006A limit (maybe R or B)
This should be easy and you may be able to use the wires you already have from the wires you removed from the L4006B
