Adding a slip tee to copper water pipe takes a some knowledge, the right tools, and a little bit of your time. Since most houses commonly use copper piping for their systems, it is not uncommon for home owners to take on simple copper piping projects, such as this one.
Step 1 - Gain Access
If you are doing a remodel, the first thing you need to do is gain access to your existing copper pipes. This often includes getting rid of any wall coverings at this point.
Step 2 - Clean
Take your steel wool and clean all parts of copper pipe inside and out. All parts you will be working with need to be cleaned until they shine like a brand new penny. Doing this will ensure a proper application of solder.
Step 3 - Measure, Cut, Test
If you have a pipe cutter, your cutting will be a lot easier, and leave your ends a lot smoother. However, if that is not an option, you can use a hack saw. A hack saw will cut through copper pipe just fine. It does, however, leave quite a rough edge on the end of the piping though.
After you have cut the pipe to the correct measurements, go ahead and test the pieces out to make sure they fit together nicely. If they fit together, then take them back apart, and do one more quick cleaning.
Step 4 - Apply flux
After you have made sure that all the debris is removed from all pieces you will be working with, it's time to apply the flux material. Using your flux brush, swipe some flux material over the joining surfaces. A light coat is sufficient, as this material works very well with just one small coat.
Step 5 - Put Together Again
Take your pieces and slide them together, just as you did when you tested them out. Use nail clamps to hold all joints together if needed.
Step 6 - Heat Things Up
Before you attempt anything with a propane torch, make sure you are following all safety precautions. Safety goggles and gloves are always recommended during this step.
You will first want to heat up the pipes and fittings using your propane torch. Use a back and forth motion until you see the solder start to bubble, and smoke a bit. When you see this happening, you know for sure that the solder is applying well. Keep doing this procedure until all is applied. You will then take the end of the solder and put around the whole joint making sure it is one hundred percent filled.
There you have it. You followed the steps, and the safety precautions, and the pipes turned out great! Good job.
Repeat this step for any additional joints that there may be.
