How to Permanently Cap Off a Water Pipe

Here are the steps to follow when permanently capping off a water pipe:

Step 1: Turn Off the Water Supply

The first step is to turn off the water supply to the pipe you want to cap off. You can do this by locating the main water valve and shutting it off. You can also shut off the valve that leads to the pipe you want to cap off.

Step 2: Drain the Pipe

The next step is to drain the pipe. You can do this by turning on all the taps connected to the pipe and waiting for the water to drain out completely. You can also use a bucket to collect any remaining water.

Step 3: Cut the Pipe

Using your pipe cutter, cut the pipe at a point close to where you want to cap it off. Make sure the cut is clean and straight.

Step 4: Clean the Pipe

Use your emery cloth to clean the end of the pipe you just cut. This will help the cap fitting fit snugly on the pipe.

Step 5: Attach the Cap Fitting

Slide the cap fitting onto the end of the pipe and make sure it fits snugly. You can use your wrench to tighten it if necessary.

Step 6: Flux the Cap Fitting

Apply flux to the cap fitting to make it easier for the solder to flow around it.

Step 7: Solder the Cap Fitting

Using your torch, heat the cap fitting until the solder melts and flows around it, sealing the fitting onto the pipe. Make sure you apply enough heat to create a strong connection. Once done, let it cool and check for any leaks.
