Faucets and toilets in any home should have a copper pipe stop valve. These allow you to make easy repairs to your toilet without getting covered in the muck, “mud” and other disgusting things that would otherwise come out while working on your pipes. Installing one of these is not a difficult task but you will probably end up working in very cramped quarters. In the following we're going to cover how to install one of these and the tools that you're going to need to do this yourself. Doing this is going to allow you to work with these pipes much more easily in the future, that way you don't have to do anything like this again. First things first. A good place to start would be to start with your tools.  

Step 1 - Buying

When you're going to buy your materials, you want to be sure to buy the correct valve. That means that the inlet of your valve needs to be accommodating to the size of pipe which extends from your wall. This is usually about a half an inch, but sometimes it's three quarters or three eighths. First thing that you're going to want to do is make sure that the threaded spout matches the supply tube's size, which will most likely be either one half an inch or three eighths of an inch. This is going to allow you to install a compression or a sweat-able valve.

Step 2 - Preparation

Next on the list of steps is make sure the water in your house is turned off. The last thing you want is to be sprayed by anything coming out of a pipe while you're working on this. Make sure to get a bucket or towel to catch debris as well; once again, you're making sure that you don't get pelted by anything nasty. 

Step 3 - Cutting

You're going to want to cut the copper pipe by using your tubing cutter; if you don't have a tubing cutter to use you're going to want to cut very slowly and softly with a close work hack saw. The hack saw however is a back up plan. If you can, make sure to get your tubing cutter.

Step 4 - Sanding and Cleaning

Next you're going to want to sand outside of the cut pipe with the combination wire brush that you prepared, some emery cloth or sand paper. Do this until it's shiny. Finally, slide a nut and ferrule on the pipe. Now believe it or not you're done, and you're going to be able to work on piping from now on without any further problems or sprays. Just turn your water back on and go about the rest of your day.
