Replacing an Outdoor Faucet Using Compression Fittings for Copper

copper fittingI have an outside silcock that I need to replace, so I’ve got hard copper here and soft copper below it, with no valve. So rather than soldering, I am going to give a couple of tricks. We are going to use compression fittings that do an excellent job of creating water tight fit on copper pipe. Especially with the solid copper, what we are going to do is cut out this, we are going to use these compression fittings.

I am probably going to put a valve here, so if we ever have a problem in the future with this silcock, we can shut off the water here and we can take our time to do any repairs. So if you don’t like to solder, if you don’t want to have to go through the process of doing all that, I will show you how to make a nice repair in copper with compression fittings.

And with half inch copper pipe, actually the outside diameters is five eights, the inside diameter is half inch, so when you get your fittings, you need to get five eights compression fittings for half inch solid copper pipe. So I shut off the water and I am using a mini tubing cutter and we are just going to make a couple of revolutions, then we are going to put a little turn on clockwise and then we’re just going to keep tightening and turning until we cut through the pipe.

outdoor spigotAnd this is a real easy convenient way if you have a small amount of space. These mini tubing cutters are doing an excellent job. I cut off this part and now we are just going to push out the old silcock and we are going to replace it with a new one. So this is the frost free silcock we are going to be putting in outside and it’s going to extend through the hole in this wall and here, as we connect the new pipe, we are going to put a shut off valve that has compression fittings on both sides.

Again, it’s five eights compression on both sides. We’ll slide it here, so if we ever have a problem in the future, we can shut it off inside and then we’ll connect all these with this compression fittings. And depending on your location, they should be cold in most locations, but it’s good to check. I have the compression fitting on this side of the pipe and now I am going to use a small nipple that I’ve cut to connect these two fittings and it’s very easy to connect.

I’ve put the little sleeve on first and then we’ll slide the nut over it and as we tighten this down, it’s beveled so that it cuts into the copper and it gives just a perfect water type fit. So I’ll slide this in here and we’ll tighten it down and on the other side we’ll put our nut first and then the sleeve and then we’ll tighten it down to the other side.

All the pipes are connected, we’ve got a new silcock outside, I have a little nipple in here between this and now we also have a shut off valve in case we ever need to change this in the future, it’s nice and convenient to shut off here. So these are the steps, we’ll go outside and I’ll show you how it looks. So we have a new frost free silcock and it’s a very easy repair whether it’s something like this going outside or something in the house. Compression fittings are an excellent way to connect copper if you don’t want to solder.
