Re: How Do I Connect This Wire?
Nice job @EdTheHeaterMan good info.You can use the search feature above and look for "How do I connect that wire" and you will be able to find this discussion... even after I'm one of the Dead Men
Maybe Erin can scoop this up and keep it somewhere where it can be found like in a file. Don't know how you would organize the different drawings though.
It is definitely a good idea with all the Nest questions we get. There are probably 2-3 every week.
That's why I started it, just so I can find it easily
Re: Caleffi Idronics milestone
I was up to date on the downloads but that was a couple of years ago. Will check
Thanks they are a wealth of information

Re: Old Toledo 1-A pipe threader
Never seen a Toledo 1-A so don't know how they work. But no the pipe threads never changed
The only variation when hand threading is how tired
the operator gets.

Sitting at home, when it is minus 34 C (Damn cold F) my bare feet on the tile floor, am feeling very grateful to the people here.
Eight or nine years ago, started hanging out here, learning & studying space heating. The knowledge gained and assistance/advice is directly responsible for giving us a very comfortable home. Learned how to do a load calc, learned about insulation and hydronics, and some interesting work processes along the way.
Thank you so much.

Re: Inquiry sent to Xylem today - Update with new circ (Grundfoss Alpha)
Thanks for all that detailed information @hot_rod.
To be clear, I have not associated any noise with the valve itself.
Instead the noise seems to be a local vibration in the boiler loop that is transmitted throughout the system piping.
In my case the noise is present when the valve is completely closed, then lessens as the valve starts to modulate, and once it's completely open at 141F the noise is gone.
When I said that I cracked open a bypass, what I meant was that I slightly opened a valve that allowed some of the return water to flow directly back to the boiler, instead of going through the Caleffi valve.
I believe that opening this bypass slightly increases the head enough so that the FPS falls below 5 and thus the noise disapppears.

Re: How Do I Connect This Wire?
One of my favorite wiring diagrams comes from @EBEBRATT-Ed
How to wire a RIB U1C relay to be used as an isolation circuit. It is generic and shows a thermostat that requires a C terminal connection, and the NO contacts of the relay to operate the boiler, but the NO contacts from the Yellow and Orange wire can operate a zone valve, or furnace, or switching relay, or what ever needs operating that the direct connection is having problems with.

Re: Weil McLain glass tube (site) replacement
Thank you both so much for the speedy responses! I will make sure to follow the rules in the future.
Re: Old Toledo 1-A pipe threader
I used to thread pipe 10 hours a day, 5 days a week. Borderline OCD about it and every single one had to be perfect. When I started I compared my results to a domestic factory made nipple and domestic fittings. It is usually 2.5-3 full rotations you can do with just your fingers. I carry only SIAM made imported fittings, and they too are only 2.5-3 rotations. It varies more once you get into the cheaper imports.
Your tool is fine it seems. 4-5 is pretty high, would definitely aim lower. Unless you're talking about full grip hand and going as much as hard as you can without a wrench, but even then I'd want it at most 3.5-4. This also means you are thinning out the pipe that much more at the tip.
I use a ridgid 300 and 1224. Should never follow their guide lines. not accurate whatsoever. I'm always above or below the line a little. I can adjust it maybe 1/16" and its a difference of the nipple going all the way inside a fitting without resistance, only going half a turn, and just right. So your teeth wearing out even a little can make a huge difference.

Re: Replacement Vent for old convector copper fin style radiator?
This is a good option. It is both a manual vent and an auto vent. You can also unscrew the top part for service or replacement. It has a ball check on the bottom part to allow removal without losing pressure or water. 1/8” NPT.

Re: Weil McLain glass tube (site) replacement
We can't talk prices on this forum. Not allowed. You can buy the parts online at supply house.com if you can change it yourself. They usually need to be changed every 5 years or so.
If it wasn't leaking before the service, I would call them and try and get some credit. They may say no but it's worth a try. Maybe when it was serviced he took it out to clean it and reinstalled it. The glass can break pretty easily.
