In this video

Place the pipe cutter around the pipe where the cut is desired. Tighten the cutter's handle until the cutting wheel makes contact, then give it an additional one-eighth turn. Rotate the entire cutter one full revolution around the pipe. Tighten the handle another eighth of a turn and rotate again. Repeat this incremental tightening and rotating process until the cutter slices completely through the pipe.

Goal: Cut the pipe to length.

  • Do not over-tighten the cutter handle at the start or between rotations, as this can damage or break the cutting wheel.

FAQs

What type of torch is best for soldering copper pipes, and how do I know I'm applying enough heat?

The K Tool International Self Igniting Propane Torch Head is sufficient for most residential copper pipe soldering. You'll know you're applying enough heat when the pipe and fitting are hot enough to melt the Oatey Safe Flo Lead-Free Solder *by touching the pipe*, not the flame. The solder should then be drawn into the joint by capillary action.

What are the critical safety precautions I must take when soldering pipes indoors?

Always have a fire extinguisher nearby and remove any flammable materials from the work area, especially when using a torch. Ensure good ventilation to disperse solder fumes, and wear safety glasses to protect your eyes from splashes or heat. It's also crucial to turn off the main water supply before starting to avoid accidents and ensure pipes are dry.

Is it really necessary to deburr, ream, and thoroughly clean the pipes before soldering?

Absolutely. Deburring and reaming with a tool like the Husky 1-5/8 in. Inner/Outer Reamer ensures a smooth pipe interior for optimal water flow and prevents solder from being blocked. Thorough cleaning with sandpaper and applying Oatey H-20 Flux are critical to remove oxidation, allowing the solder to properly bond and create a strong, watertight seal.

What are the most common reasons a soldered joint might leak, and how can I avoid them?

Leaks often occur due to insufficient cleaning, inadequate heat application, or not using enough solder. Ensure pipes are shiny clean before applying Oatey H-20 Flux, heat the joint evenly until it can melt the solder, and feed enough solder to completely fill the joint. If a joint leaks, it must be desoldered, thoroughly cleaned, and resoldered.

Insert a length of pipe into the tristand and yoke and tighten the yoke handle. Slide the pipe cutter onto the pipe and tighten it just one eighth turn after the cutting wheel makes contact with the pipe. Do not over tighten it or you can ruin the cutting wheel. Rotate the cutter one full turn around the pipe and then tighten the handle an additional one eighth turn. Continue this until the cutter slices through the pipe.
