Galvanized pipe is perfect for DIY plumbing projects because it’s affordable, corrosion resistant, and easy to work with. Using galvanized pipe as a cap for off-standard PVC or copper pipe is an excellent way to protect those pipes from the elements. Follow these steps to learn how to cap off galvanized pipe quickly and easily. Capping galvanized pipe protects the plumbing from rain, snow, and other outdoor elements that can cause damage over time.
How To Cap Off Galvanized Pipe
We’ll show you how to caulk and cap galvanized pipe in 5 simple steps:
Step 1: Measure and cut the galvanized pipe.
First, you’ll need to determine the length of your pipe. You can use a measuring tape to get the distance from the center of the pipe coming out of the ground to the top of the pipe when it’s sitting on a level, horizontal surface. Next, you’ll need to cut the pipe to length. To do this, you can use a pipe cutter—a handy tool that’s designed to quickly and precisely cut through pipes. You can also use a hacksaw. If you do use a hacksaw, make sure you’re wearing protective gloves. Measure the distance from the ground to the top of the pipe, then add about 2 inches for the diameter of the rubber gasket. This will give you the length of the pipe you’ll need to cut. Remember to account for the amount of pipe that will be going inside the ground. Your total length will be the measurement from the center of the pipe coming out of the ground to the top of the pipe on a level surface plus the depth of the pipe that will be buried.
Step 2: Clean the pipe and the area around it.
Before you caulk the pipe, you’ll want to clean it. Doing so will help make sure your caulk adheres properly. There are a few different methods you can use to clean your galvanized pipe: – Soap and water: Clean the pipe with soap and water to remove dirt, oils, and other debris that can get on the pipe and prevent the caulk from adhering. – Sandpaper or a wire brush: You can also clean the pipe with sandpaper or a wire brush to remove dirt and any rust or corrosion on the surface of the metal. – A solvent like mineral spirits or acetone: You can clean the pipe with a solvent like mineral spirits or acetone to remove dirt and oils from the surface.
Step 3: Install the rubber gasket.
The purpose of the rubber gasket is to create a seal between your PVC or copper piping and the galvanized cap. The gasket will prevent water and other elements from seeping into the cap. The type of gasket you use will depend on the type of PVC or copper pipe you’re using. If you’re working with schedule 40 PVC, you’ll want to use a gasket made for schedule 40 PVC. For schedule 80 PVC, use a gasket made for schedule 80 PVC. To install the gasket, put the pipe in the cap, then put the gasket on top of the pipe. Make sure you push the gasket into the grooves on the inside of the cap.
Step 4: Apply caulk and install the cap.
Use a caulk gun to apply a strip of caulk to the top of the pipe where it meets the cap. This will create a seal that will prevent rainwater, snow, and other elements from entering the cap and damaging the PVC or copper pipe. Make sure the caulk you use is designed to be used indoors. You can use black or white caulk—you don’t need to match the caulk to the cap colour. Next, place the cap on top of the pipe and screw it into place. Tighten the cap by hand until it’s snug. Be careful not to over-tighten the cap, as this could damage your PVC or copper pipe. This is where a crescent wrench comes in handy.
Step 5: Test your work and enjoy!
Finally, test your work to make sure the caulk and cap are working properly. Take a garden hose and spray the cap for about a minute, then check for any leaks. If you see a leak, use a knife to remove the cap, then reapply caulk and replace the cap. You can also use a soap and water solution to look for leaks. If you find a leak, re-apply caulk and retighten the cap. Once you know everything is working properly, enjoy your new capped off galvanized pipe! You’ve successfully capped off your galvanized pipe, saving you time, money, and energy. This DIY project is a great way to protect your PVC or copper piping from corrosion and damage caused by rain, snow, and other outdoor elements.
