Final Water Line Connection — Installing the Bathroom's Water Supply Lines
Part of project
Bathroom Plumbing Installation: A Complete DIY Guide · Step 2 of 5
In this video
With the system fully assembled and mounted, the final connection to the house's water supply can be made. Ensure the main water is shut off. In the trench, use a pipe cutter to cut the existing main water pipe (in this case, a black poly pipe). Clean the ends of the pipe. Connect the new copper pipe assembly from the filter system to the main line. This is done using transition fittings that adapt from copper to poly pipe. Crimp the press-fit fittings on the copper side and securely attach the fittings to the poly pipe, completing the plumbing connection.
Goal: Connect the filter system to the house's main water supply
- CRITICAL: Ensure the main water supply to the entire house is shut off before cutting the existing pipe.

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.
