Re: What's a good humidity meter?
Sling is probably cheaper and accurate. Humidity is always a moving target.
Re: Myers C48D53B86 jet pump- Help
I['ll bet it is an 1/8 npt if you take the brass out? A basic 1/8 radiator bleeder, ball valve, etc.

Re: Myers C48D53B86 jet pump- Help
How far could it have gone ?
Is the bleeder Petcock thread into the casting 1/8" pipe thread ? Maybe just put another valve on it.
Re: Radiators make my apartment unbearable during winter
IMO, the problem here is you don't have a thermostat in YOUR apartment. The thermostat controls the level of temperature it senses. If the thermostat is cold, it's telling the system to add more heat.
If the thermostat senses too much heat, it tells the system to stop sending heat.
Thermostatic radiator valves would do what you want, but the landlord won't provide them, and you can't.
So, YOU need to be the thermostat. If the radiator valves won't close, you can cover the radiators so they emit less heat, and/or open windows to get rid of the excess heat.
Re: Old copper pipe smaller than todays 1/2"
Regular domestic water plumbing is measured by it's ID and refrigeration tubing is by OD. So, someone may have used 1/2" OD in lieu of 1/2"ID especially if that person was in the refrigeration or A/C business. Try going to a refrigeration supplier and buying couplers for 1/2"OD and see if that works. 1/2" copper for domestic water has an OD of 5/8" while 1/2" refrigeration tubing has an OD of 1/2". So, for example, 5/8" refrigeration tubing is the same as 1/2" nominal domestic water tubing. I said nominal since the actual ID of domestic water tubing changes with the grade of the tubing being M, L, or K, while the OD remains the same.

Re: New steam boiler - newbie help
What was your total EDR (sq. ft. of steam)? Avoid working in BTU, it's a recipe for confusion
Re: New steam boiler - newbie help
Look for a steam boiler with a "Sq Ft of Steam" rating of 300-330. Always round down to the smaller boiler if you land between two of them. Others will disagree with me on this, no doubt.
Re: Adjacent bedrooms. ERV / Mini split setup
I have no idea what the ERV is for. It won't accomplish anything. However, you can get some air movement with two vents, as noted above — and with a fairly powerful fan in one of them. A bathroom fan is nowhere near big enough. I'd try it without any ducting first.
Fans are noisy.…
Re: What's a good humidity meter?
Bacharach Sling Psychrometer is the standard for measuring relative humidity
https://www.grainger.com/product/BACHARACH-Sling-Psychrometer-6T173
As far as a "humidistat" to operate a humidifier or dehumidifier is concerned, there are many different models that can be employed. I have never found any of them to be that accurate. Calibration is the key to proper humidity control. A standard combination Thermometer/hygrometer for measuring temperature and humidity with an analogue dial readout can be purchased for less than $10.00 on amazon. Likewise the digital version is also available for under $10.00. For accuracy, you can calibrate any device when you place it in the room you want to measure for 24 hours, then use the Sling Psychrometer to measure the accurate RH then set the inexpensive dial meter to the proper RH based on the accurate reading measured by the professional instrument.
