Shower Valve Replacement Made Easy (Delta 1700 Install Step-by-Step)

What happens here

Insert the new Delta shower valve body into the wall opening, connecting the PEX lines to its appropriate fittings. Before pressing, ensure the PEX lines are fully seated by looking for the black indicator mark on the fittings; this mark should disappear when the PEX is pushed in completely. Using the Ridgid RP 115 press tool with the correct PEX jaws, crimp both PEX connections. Leave the top copper connection unpressed temporarily to allow for flexibility in adjusting the valve's position.

Goal: Securely install the new valve body and connect PEX piping.

What they say

Hide

That's how they secured this thing. Yeah. We can leave those two clips in the wall, but we got that piece of copper out of there. Oh, yeah. I think that works out really well. I think that's going to work out awesome. Okay. Yeah. Look at that. Straight flush. My cut wasn't the grandest. I got it out of there. We wanted to go up just a little bit more anyway. I'm going to ProPress up here. Going to hit up the pencil reamer right here and here as well to get a little Scotch-Brite here. I will chamfer that sometimes as well. But really, with just a Scotch-Brite is going to allow for just an easy slip over. There really is no hard jagged edge on this because of that cut and then the Scotch-Brite is just going to dull it down and allow the ProPress to slip right over it. And that's nothing. It's awesome. But, I didn't 100% know what I was working with here. So, I got this as a slip coupling. That means there's no indentation, and it's going to slide the whole way up so that I could slide it down if I had to. So, with that, you want to do yourself a favor, and you want to mark the halfway spot with this. Probably easiest to do it right here. And you can look down in there and measure what the halfway spot is. Or you can measure the whole thing and split the difference. You want to make sure these fittings are pushed all the way together. They're pushed in place. And then mark this one, too. You can see that's black right now. Once we get that the whole way in, that's the indicator to tell you that your PEX is where it needs to be. I'm going to get the PEX pressed in place. We're still going to have some flexibility to move and get this lined up on the other side. So, when I shoot my screws in, this is where it's going to go.
