This OJT tutorial presentation is exactly how the seven to twelve-minute talkers recommend. The music was great too. I think I might wrap the valve bodies with a damp rag to prevent the imaginable from happening. Thanks for sharing. LIKED, SUBSCRIBED, & DING!!!
Kevin Thanks for your comment it is appreciated. To each his own on sweating. At 77 years old and sweating pipes more than 50 years I have hundreds of valves out there using that technique in the video never having an issue. In fact just the other day I was looking at some valves I sweated & beaded 29 years ago and they are still in excellent shape. That's a good feeling to see. Best Regards.
Solder application is not ideal but should be able to make a basic joint but the way he heats, I suspect the penetration of the solder into the joint will not be ideal but will be minimal with a risk of small gaps. A wet rag should also be used to protect the seals in the valve.
Having sweat hundreds of Gate & Ball Valves in the last 50+ years with also checking penetrations periodically I have never had an issue with my sweat joints. The key is knowing how to apply the heat properly. I maintain a Journeymen Plumbers and also have a Master Plumbing & Heating license (Mechanical Administrator) with the state of Alaska. TurtleWaxed , your comment is absolutely great and I certainly appreciate it Thank You! Also look at my other comments below.
Capillary action ... is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity. Answer: Very Easy! Google Capillary Action sweating. In our trade language its not "solder" it's sweat the pipe. Thanks for your comment!
Good Question!! As an example Hammond Valves recommends in the open position: www.hammondvalve.com/data/files/SolderingTechnique.pdf Personally, for my own reasons I prefer to sweat a Gate, Ball, or any other in the closed position.
Nakco Educational You should sweat it open Closed you could damage the Teflon bushing inside by building up pressure in the tiny space were the brass chrome ball is sitting
Good thoughts Mike, however I have been sweating ball valves closed for many years and never had a problem with them. Biggest problem I have seen open is solder going into the valve and not being able to closed it. Gate valves are famous for that.
this expands the valve, the space between the pipe and fittings increases causing it to make a water tight seal nearly impossible. unless all your work is the top side of vertical plumbing that is ;)

How hard could it be to solder a downward vertical joint?

Should the valve be open or closed?

Open is preferred, to allow gases to release immediately and excess solder to flow freely, if there's excess

You should sweat it open

Add a small wet rag on the bolt we’re the handle is before and while sweating leave it there till your don so the Teflon part doesn’t heat up as much

Some professionals will fail this becouse they said never heat valve first always heat pipe and then valve so less stress on valve component
Thanks for your comment, Joe!

Sweet
As the video says, "Thanks for Watching" & your comment!!!
this is exactly how to solder---heat valve, pipe etc evenly around entire area--NOT just on one side, let solder follow the heat--perfect.
Thanks, Jeff!
