Cutting a tee is a basic plumbing task that can be easily accomplished with the right tools and a little know-how. Whether you are a homeowner looking to make a simple repair or a plumber in training, understanding how to cut a tee is an essential skill. In this article, we will provide a step-by-step guide on how to cut a tee, including the necessary tools, safety precautions, and detailed instructions. By following these steps carefully, you can ensure a clean and precise cut that will result in a secure and long-lasting plumbing connection.

Before we begin, it is important to gather the necessary tools for the job. You will need a hacksaw, a miter box, a pencil, a ruler or tape measure, and a deburring tool. A hacksaw is a type of saw that is used for cutting metal pipes. A miter box is a tool that helps to guide the hacksaw and ensure a straight cut. A pencil is used to mark the cutting line on the pipe. A ruler or tape measure is used to measure the desired length of the cut. A deburring tool is used to remove any sharp edges from the cut pipe.

Once you have gathered the necessary tools, you can begin the process of cutting the tee. First, use the pencil and ruler or tape measure to mark the desired cutting line on the pipe. Next, place the pipe in the miter box and align the cutting line with the saw blade. Hold the pipe securely in place and begin sawing slowly and carefully. Once the cut is complete, use the deburring tool to remove any sharp edges from the pipe. Finally, insert the tee into the cut pipe and secure it with the appropriate fittings.

Selecting the Right Materials

Tools

Choosing the appropriate tools is crucial for a clean and precise cut. Here are the essential tools you’ll need:

Scissors: Invest in sharp, high-quality scissors designed for cutting fabrics.
Measuring Tape or Ruler: Ensure precise measurements for symmetrical and even cuts.
Marking Tool: Use chalk or fabric markers to temporarily mark the cutting lines on the fabric.
Iron and Ironing Board: Pressing the fabric before cutting helps to remove wrinkles and ensure straight cuts.
Pins: Use pins to secure the fabric layers together before cutting to prevent shifting.

Fabrics

The type of fabric you’re working with will influence your cutting technique. Consider the following factors:

Weight: Lightweight fabrics like silk and chiffon require more delicate handling than heavier fabrics like canvas or denim.
Texture: Textured fabrics like corduroy or velvet may require special scissors or cutting techniques.
Grain: The grain of the fabric refers to the direction of the threads. Cutting with the grain ensures a more stable and less likely to fray.

Additional Considerations

Beyond tools and fabrics, here are some additional considerations for selecting the right materials:

Pattern: Refer to the pattern instructions to determine the specific materials and cutting requirements.
Interfacing: Interfacing can provide stability and support to certain areas of the garment, such as collars or cuffs.
Thread: Choose thread that matches the fabric weight and color for optimal stitching results.

Marking the Pipe

Before cutting, you need to mark the pipe accurately to ensure a precise cut. Here are the steps involved:

1. Measure and Mark the Cutting Point

Using a measuring tape, determine the desired length or location where you need to cut the pipe. Mark this point clearly with a permanent marker or a scratch awl. Ensure the mark is perpendicular to the pipe’s axis.

2. Determine the Centerline

Finding the pipe’s centerline is crucial for marking the angles accurately. For round pipes, use a T-bevel to mark a horizontal line through the center of the pipe at the cutting point. For square or rectangular pipes, mark the center points on each side and connect them with a horizontal line.

Alternatively, you can create a “trammel” using a piece of string and a pencil. Tie the pencil to the string and hold it taut while wrapping the string around the pipe. Mark the intersection point of the string on opposite sides of the pipe to form the horizontal centerline.

3. Extend the Line for Angle Measurement

Extend the horizontal centerline past the cutting point by at least 3 inches. This extended line will serve as a reference for measuring and marking the angles for the tee connection.

Marking Method	Description
Permanent Marker	Use a waterproof, permanent marker to make visible marks on the pipe.
Scratch Awl	Mark the pipe by scratching it with a sharp awl. This method is less noticeable than using a marker.
Center Punch	Create a small indentation on the pipe using a center punch. This method is more permanent compared to other marking methods.

Cutting the Pipe

To cut the pipe, you will need a pipe cutter. A pipe cutter is a tool that is used to cut pipes. There are different types of pipe cutters, but the most common type is the manual pipe cutter. A manual pipe cutter is a handheld tool that has a blade that is used to score the pipe. Once the pipe has been scored, you can break the pipe by bending it back and forth.

Tools Required	Purpose
Pipe Cutter	To score and cut the pipe
Deburring Tool	To remove any sharp edges from the cut pipe
Measuring Tape	To measure and mark the pipe before cutting
Safety Glasses	To protect your eyes from flying debris

Scoring the Pipe

To score the pipe, place the pipe in the pipe cutter and tighten the cutter until the blade makes a deep score in the pipe. The score should be about 1/3 of the way through the pipe. Once the pipe has been scored, you can break the pipe by bending it back and forth. If the pipe does not break easily, you may need to score it deeper.

Breaking the Pipe

To break the pipe, bend the pipe back and forth at the score mark. The pipe should break easily at the score mark. Once the pipe has been broken, you can use a deburring tool to remove any sharp edges from the cut pipe.

Deburring and Cleaning the Pipe

Once the cut is complete, it’s important to deburr and clean the pipe to remove any sharp edges or debris. This will help prevent scratches or damage to the pipe when it’s inserted into fittings or other components.

Tools and Materials:

To deburr and clean the pipe, you’ll need the following tools and materials:

Deburring tool
Sandpaper (120-grit or finer)
Pipe cleaner
Rubbing alcohol or acetone

Steps:

Deburring: Insert the deburring tool into the end of the pipe and rotate it to remove any burrs or sharp edges.
Sanding: Use sandpaper to smooth the edges of the pipe. Start with a coarse grit (120-grit) and work your way to a finer grit to ensure a clean finish.
Cleaning: Use a pipe cleaner to remove any debris from the inside of the pipe. Dip the pipe cleaner in rubbing alcohol or acetone for better cleaning.
Drying: Allow the pipe to dry completely before proceeding with any further steps.

Deburring Methods	Description
Reaming	Using a reamer to smooth and enlarge the inside diameter of the pipe end.
Filing	Using a file to manually remove burrs and sharp edges.
Rotary Burring	Using a rotary burr tool to quickly and effectively remove excess material.
Beveling	Creating a slight angle (bevel) at the edge of the pipe end to reduce stress concentration.

Securing the Tee with Solvent Weld

Solvent weld is a chemical adhesive used to join PVC pipes and fittings. It works by dissolving the surface of the pipe and fitting, creating a strong bond when the pieces are pressed together.

Step 1: Clean the Tee and Pipe

Using a clean rag and solvent cleaner, remove any dirt, debris, or grease from the surfaces of the tee and pipe. Allow the surfaces to dry completely.

Step 2: Apply Solvent Weld

Apply a thin, even layer of solvent weld to the inside of the tee. Use a brush or applicator to evenly distribute the solvent. Avoid using excessive amounts of solvent, as this can weaken the bond.

Step 3: Insert the Pipe

Insert the pipe into the tee, ensuring that the pipe is fully seated. Press the pieces together firmly for several seconds. Hold the pieces securely in place while the solvent weld dries.

Step 4: Inspect the Joint

Once the solvent weld has dried, inspect the joint for any gaps or leaks. If any gaps or leaks are found, the joint will need to be redone.

Step 5: Cure Time

The solvent weld will typically take several hours to fully cure. During this time, avoid applying any pressure to the joint.

Step 6: Additional Tips

For best results, follow these additional tips:

Tip	Description
Use the correct pipe size	Ensure that the tee and pipe are the correct size for the application.
Use a clean brush or applicator	A dirty brush or applicator can contaminate the joint and weaken the bond.
Allow the joint to dry completely	Applying pressure to the joint before the solvent weld has fully cured can weaken the bond.
Store the solvent weld properly	Solvent weld should be stored in a cool, dry place. Avoid exposing it to heat or direct sunlight.

Threaded Tee Installation: Preparing the Pipe

7. Threading and Deburring the Pipe

Once the pipe is cut to length, it’s time to thread it. This is done using a pipe threading machine or a manual pipe threader. The type of threading machine you use will depend on the size and thickness of the pipe. Once the pipe is threaded, it’s important to deburr the ends. Deburring removes any sharp edges that could damage the threads or cause leaks. To deburr the ends of the pipe, use a file or a deburring tool.

Pipe Size (IPS)	Die Size (IPS)
1/2″	3/4″
3/4″	1″
1″	1-1/4″
1-1/4″	1-1/2″
1-1/2″	2″

To determine the appropriate die size for a particular pipe size, consult a pipe threading chart. The chart will indicate the correct die size to use for each pipe size. Once you have determined the correct die size, install the appropriate die into the threading machine.

To thread the pipe, insert the pipe into the threading machine and secure it in place. Start the threading machine and slowly feed the pipe through the die. As the pipe is threaded, the die will cut threads into the pipe. Continue threading the pipe until the desired length has been threaded.

Threaded Tee Installation: Applying Pipe Dope

Applying pipe dope to a threaded tee before installation helps to create a watertight seal and prevent leaks. Here’s how to do it properly:

Clean the threads: Use a wire brush or a piece of sandpaper to clean any dirt or debris from the threads of the tee and the pipe nipples you’ll be connecting to it.
Wrap the threads with pipe dope: Apply the pipe dope in a clockwise direction, starting at the base of the threads. Use a sufficient amount to cover the entire length of the threads, but avoid over-applying.
Tighten the fittings: Hand-tighten the tee onto the pipe nipples until you feel resistance. Then, use a wrench to tighten the fittings further, but don’t overtighten.

Applying Pipe Dope to Threaded Tees

For a more detailed explanation of applying pipe dope to threaded tees, follow these steps:

Select the correct pipe dope: There are various types of pipe dope available, each designed for specific applications. Select the one that is appropriate for the materials and the purpose of the installation.
Clean the threads: Remove any dirt, debris, or burrs from the threads of the tee and the pipe nipples using a wire brush or a piece of sandpaper.
Apply the pipe dope: Apply a thin, even layer of pipe dope to the male threads of the pipe nipples. Wrap the pipe dope in a clockwise direction, starting from the base of the threads and working towards the top. Avoid applying excessive amounts of pipe dope.
Tighten the connections: Hand-tighten the pipe nipples into the threaded tee until you feel resistance. Use a wrench to further tighten the connections, but do not overtighten.

Pipe Dope Type	Applications
Teflon tape	General plumbing applications, including potable water lines
Pipe dope with PTFE	Gas lines, hydraulic systems, and applications with high temperatures or pressures
Anaerobic pipe sealant	Metal-to-metal fittings, applications with vibration or shock

Threaded Tee Installation: Tightening the Tee

9. Tighten the Tee:

a. Once the tee is properly aligned, carefully tighten the pipe with a pipe wrench or other suitable tool. Avoid overtightening, as this can damage the tee or the pipe.

b. Use a torque wrench if available to ensure the tee is tightened to the proper specifications. Refer to the manufacturer’s instructions for recommended torque values.

c. If using a pipe wrench, hold the tee firmly in place with one hand while tightening the pipe with the other. Apply an even force around the circumference of the tee to distribute the pressure.

d. Keep checking the alignment of the tee as you tighten it. Minor adjustments may be necessary to ensure the tee is properly oriented.

e. Continue tightening the tee until it is secure and there is no longer any movement or leakage.

Pressure Testing the Tee Joint

10. Leakage Inspection

Once the weld bead has completely cooled, it’s time to inspect the joint for any potential leaks. This can be done by pressurizing the Tee joint with water or air. Here are the steps for conducting a pressure test:

Connect a pressure gauge to the Tee joint.
Slowly increase the pressure inside the joint until it reaches the desired test pressure.
Monitor the pressure gauge to ensure it remains at the desired pressure for a specified amount of time (typically 15-30 minutes).
Inspect the Tee joint thoroughly for any signs of leakage or deformation. Look for water seepage or bubbling if using water, or listen for air escaping if using air.
If no leaks are detected, the joint has passed the pressure test.

The pressure test is a crucial step in verifying the integrity of the welded Tee joint. By applying pressure and inspecting for leaks, you can ensure a reliable and safe connection.

Additional Tips for Pressure Testing

– Use a pressure source that can maintain the desired test pressure for an extended period.
– Apply a soapy solution or leak detection fluid around the weld area to help identify even the smallest leaks.
– If leaks are detected, mark their location and proceed to repair the joint.
