Hello, everyone, I'm Joshua Clement with Lighty Contractors. And today, I'm going to talk to you about how to install a union on your copper plumbing. Now, there's two different kinds of unions. One, you actually have to solder in two different pieces and join them together with threads. The other, which I prefer, is a Quick-Connect. The reason I like this is because all you do, is push your tube pipes into each side and the job's done. You don't have to go and do all your welding, deal with the torch and all of that. And the price difference isn't very much. When you're installing one that you actually have to solder in, you'll need a torch, flex, solder, something to put your flex onto your pipe with, and an emery cloth. Now, we will not be doing this method. Reason being, it takes a lot of time and materials and time is money. So, we will be using the faster method with the Quick-Connect. This Quick-Connect is just a pressure fitting system. It has these little tubes that you take and slide in there. And there's teeth on the inside that grab onto your pipe and won't let it go, unless you pull this back and pull it out. To keep it from doing that when just water's running through it, they have these stops. After you put it onto your copper, you take this stop and slide it right down, over that. That way, it can't be released and pop off on you. So, we'll take the plastic tube, insert it into the Quick-Connect. Grab our copper plumbing, make sure that the plastic tube goes through the inside of the copper plumbing and just press it on. Then, we'll do the same thing to the other side. Now, we have a nice, tight fit that's not coming off. If you want to change something up, all you have to do, is pull it together, press on this little plastic piece on the end and peel it off. You can see where the teeth have grabbed onto that copper. And it won't let it go until I depress the plastic piece that allowed the teeth to slip off. I'm Joshua Clement with Lighty Contractors, thank you all for watching and good luck with this project.
