So how do you replace a leaking trader valve while the system is running? You use this tool, so this is arader valve removal tool. So you have an AC that leaks and you can't find the leak, and after you test everything, you go outside to the line set. You see two shrader valves and you see the caps missing and you put bubbles on it and it's leaking well.

How do you replace this valve without taking all the refrigerant out of the system? Welcome to a Shrader valve removal tool. This is one of the best tools that I've ever used in the field. It's valuable, it's helpful, and it saves a ton of time, and of course, I'll have a video. To show you what it's like in the field, but basically the way that this works is you have a ball valve.

This is where your AC gauges go, so you can get a reading while you're doing this. This ball valve will turn off access and this will no longer go in to get access to the valve. When I open this, you can see. That the end of the Shrader valve removal tool is here. So what you'll do is you'll hook this up to the unit outside.

You'll make sure that this line is open. You push this in and you keep pressure on it because once you loosen the shrader valve that's now connected to. There you go. You'll be able to turn this, but because the line is pressurized, this will want to push out, so you have to keep constant pressure on it as you turn it.

And slowly the shrader valve will start to come out, and then you can just release the pu, the pressure of pushing, and this will push out by the pressure of the gas. So now you turn this L valve shut, and when you remove this coupling.

You now have access to the shrader valve, so you can remove this shrader valve. Put a new one on. Align this. Put the valve back into the tool. Tighten the fitting. And remember, snug not extremely tight, good and snug. Perfect. Now put the ball valve in line so the plunger can push in. And now you can see the valve.

And you keep pressure on this like you did before, and you turn this and you tighten it until it's snug, then you'll remove the tool.

You'll hear a gas release, a hiss, and then you will have left this valve into the new system. And without removing any refrigerant, you have now replaced. A shredder valve that was leaking. And I have to tell you, if you don't have this tool, it's going to usually take several hours, I would say one to four hours, usually two or three to remove the refrigerant, pull a vacuum, put nitrogen in alliance, replace this, and then go through the charging process again.

So this tool is amazing and it's inexpensive when you buy it, it will usually come in a kit in a bag like this, and in that bag you'll have a. A number of these shrader valve caps, and then you'll have a bag of shrader valves and you have to make sure that you get shrader valves that are rated for refrigerant.

And of course, that's what comes with the kit.
