To begin, prepare the copper pipe for the connection. Use a pipe cleaning tool to scrub the exterior of the pipe's end until it is clean and shiny. This removes any oxidation or debris that could interfere with the seal. Next, take a deburring tool and insert it into the open end of the copper pipe. Twist the tool to smooth out any sharp edges or burrs left from cutting. This step is critical to prevent damage to the rubber seal inside the press fitting.

Goal: Prepare copper pipe for fitting

  • The deburring step is essential to avoid damaging the rubber seal inside the press fitting, which could cause a leak.

FAQs

How difficult is this project for a beginner, and is the 4-hour estimate accurate?

This project is rated beginner-friendly, but taking your time, especially with pipe cutting and compression fittings, is crucial. The 4-hour estimate accounts for preparation, potential draining time, and careful installation, so allow yourself ample time to avoid rushing and ensure a leak-free result.

What are the most common mistakes when using compression fittings, and how can I prevent leaks?

Leaks from compression fittings often stem from not deburring pipe ends properly, misaligning the nut, or over-tightening. Ensure pipe ends are smooth and square, hand-tighten the nut, then use a wrench for another 1/2 to 3/4 turn for a secure seal, being careful not to overtighten and strip the threads.

The guide lists multiple copper pipe cutters; which one is best for this project, and is a deburring tool essential?

A close-quarters tubing cutter or an AUTOCUT 1/2 in. cutter is ideal for working in tight spaces common under sinks or behind walls. Yes, a deburring tool like the Husky 1-5/8 in. reamer is absolutely essential to ensure a smooth, clean pipe end for leak-free compression fitting connections.

What are the most important safety precautions to take during this water hammer arrestor installation?

Always shut off the main water supply and drain the lines completely before cutting. Wear safety glasses to protect your eyes from metal shavings, and be cautious of sharp pipe edges after cutting. Have towels and a bucket ready for any residual water to minimize mess.
