Once the installation is complete and all connections are tight, it's time to check for leaks. First, ensure all taps that you opened are now closed. Go to your main water shut-off valve and turn it back on slowly. Listen for the sound of water filling the pipes. Return to your work area and carefully inspect each of the new joints for any signs of dripping water. Use a dry paper towel to wipe the joints, which will make even the smallest leak visible. If you find a leak, turn the water off again and slightly tighten the connection before re-testing.
Goal: Verify a leak-free installation
- Do not leave the area unattended immediately after turning the water back on. Stay and observe the new fittings for several minutes.

FAQs
How accurate is the 12-hour estimated time, and what factors could significantly extend this project for a DIYer?
The 12-hour estimate is for an intermediate DIYer in ideal conditions. Unexpected issues like significant wall damage, corroded old plumbing, or difficult-to-remove fixtures can easily double the project time. Always allocate extra time for unforeseen challenges, especially during demolition.
What is the absolute first safety step, and what should I do if I can't turn off the main water supply?
Always turn off your home's main water supply before starting any demolition or disconnection. If you cannot locate or operate your main shut-off valve, contact a professional plumber immediately. Proceeding without cutting the water can cause severe flooding and significant property damage.
Beyond the basic hand tools, what specialized tools or materials are crucial for ensuring a leak-free faucet installation with PEX or CPVC?
For PEX, a dedicated PEX crimp tool and appropriate crimp rings are essential for secure connections. If using CPVC, you'll need CPVC primer and solvent cement. Always use plumber's tape or thread sealant on all threaded connections and plumber's putty for the tub drain assembly to prevent leaks.
What is the most common mistake DIYers make that leads to leaks after installation, and how can I avoid it?
The most common mistake is failing to properly seal connections or not adequately tightening fittings. Ensure all PEX/CPVC connections are correctly crimped or glued, and all threaded connections are wrapped with Teflon tape and firmly tightened. During the leak test, turn water on slowly and meticulously inspect every joint for drips.
