So we're going to start with the water connection. Now any plumbing fixtures you have a separate service shut off, we're going to install one like this right on this pipe. But right now we have full water pressure behind that pipe so we don't want to cut it yet. What we need to do is to shut the water coming into the house. Line over that is. Go do that, great. All right Richard, I've shut off the main and opened up all the sinks upstairs. All right. So let's open up this faucet right here. Some of the last of water will drip out but we won't get all of it. So there's still going to be some water right here so when we cut it, we'll catch it in the shallow pin. Now before we cut it, I always like to clean the pipe first so this is an emery cloth. All right, that looks clean enough. Now we are going to install this shut off and if it's a solderless connection, there's a nut right here we'll tighten up and they also have this nice chrome flange. So we actually want to cut the pipe off right about there. Good. Okay, here it comes. Not too bad. Now we put our discussion plate on and now this is our compression stop and the connection is made up of a nut, a brass ring that goes over the copper and the fitting itself. So there's the nut, the brass ring goes over the copper and now as we tighten up this nut, it'll actually deform that brass ring right down onto the copper so tight that it makes a watertight connection. So we snug it up by hand and finish it off with two wrenches. All right, so the water's back on, our shut off is holding tight.
