Tie into Main Water Supply — Installing the Bathroom's Water Supply Lines
Part of project
Bathroom Plumbing Installation: A Complete DIY Guide · Step 2 of 5
In this video
Identify the main hot and cold copper supply pipes in the ceiling or wall. Cut into these pipes at the appropriate locations using a pipe cutter suitable for copper. Use push-to-connect T-fittings to tap into the lines. These T-fittings will connect to the existing copper pipe on two ends and provide a 1/2-inch push-to-connect port for the new PEX lines. Run the hot and cold PEX pipes from the shower valve and connect them to their corresponding T-fittings on the main supply.
Goal: Plumbing Pipes Installation
- Ensure the main water supply to the house is shut off before cutting into any existing pipes.
Used in this video
- Pipe Cutter (Tool Type: Cutting Tool, Power Source: Manual) — Cutting existing copper pipes and new PEX pipes.
- Deburring Tool (Tool Type: Hand Tools, Power Source: Manual) — Cleaning the ends of both the copper and PEX pipes.

FAQs
Given the 'intermediate' difficulty and '30 hours' estimated time, is this project suitable for someone with limited plumbing experience?
This project is challenging and requires careful attention to detail and local codes. While an intermediate rating means it's not for total beginners, someone with strong DIY skills can succeed by researching thoroughly and starting with smaller plumbing repairs first. Be prepared for potential time overruns, as unforeseen issues can extend the project timeline significantly.
Are the specialized tools like the SharkBite PEX cutter and Crescent pipe wrench absolutely necessary, or can I use more common tools?
While you might be able to use a hacksaw for PEX or standard adjustable wrenches, the specialized tools are highly recommended for efficiency, accuracy, and ease of use. The PEX cutter ensures clean, straight cuts crucial for leak-free connections, and a self-adjusting pipe wrench simplifies working in tight spaces and applying correct torque. Investing in these tools will save frustration and potential rework.
The materials list mentions PEX. Is PEX the best choice for a DIYer compared to traditional copper or CPVC, and why?
PEX is generally an excellent choice for DIYers due to its flexibility, ease of installation, and fewer connection points compared to rigid copper or CPVC. It requires fewer specialized soldering skills (unlike copper) and is more forgiving than CPVC for mistakes. The ability to run long, continuous lines reduces the risk of leaks associated with multiple fittings.
What are the most critical plumbing codes or safety precautions I need to be aware of when installing bathroom plumbing?
Always shut off the main water supply before starting any work and drain the lines. Crucially, familiarize yourself with your local plumbing codes regarding drain line slope, venting, trap arm distances, and pipe sizing, as non-compliance can lead to failed inspections, health hazards, or costly rework. Proper ventilation prevents sewer gases from entering your home and ensures proper drainage.
