How to Use an Internal Pipe Wrench

An internal pipe wrench can help in replacing old water pipes.

Internal pipe wrenches are a valuable tool for repairing broken pipes. Rusty plumbing pipes tend to break off, and you cannot get a grip with an external wrench. An internal pipe wrench grips the broken pipe inside to unthread the pipe. Using an internal pipe wrench requires using a separate wrench to turn it. Internal wrenches have one end that is tapered or a square knob for a wrench. The working end of the pipe wrench has circular jaws that pivot as it is turned to grip the pipe.

Things You'll Need

• Adjustable wrench

Instructions

1. Insert the pipe wrench into the pipe with the square end of the wrench pointing toward you. Slide the wrench into the pipe about 1 inch to get a good hold on the inside diameter of the pipe.

2. Adjust the jaws of your adjustable wrench to fit over the end of the pipe wrench.

3. Hold the internal pipe wrench with one hand. Turn the internal pipe wrench counterclockwise with the adjustable wrench in your free hand until the internal wrench grips the pipe.

4. Release your hold on the internal pipe wrench and continue turning counterclockwise with the adjustable wrench until the pipe comes free.
